Outdoor Airflow Measurement System Engineered for accuracy, applicability, durability and simplicity in HVAC air systems
Model OAFE-1500 Outdoor Airflow Measurement System
T
o meet ANSI/ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality and the energy efficiency requirements of the “green building movement”, Paragon Controls Inc. developed an AMCA certified outdoor airflow measurement system (Model OAFE-1500) that is capable of producing an overall ±0.5% accuracy through the velocity range of 200 to 1,200 fpm and ±5% accuracy at 100 fpm.
The Environmental Protection Agency (EPA) reported that, “the economic losses to the nation due to indoor air pollution are in the tens of billions of dollar per year,” and suggested that “modest investments toward improved indoor air quality would generate substantial returns” (Energy Cost and IAQ Performance of Ventilation Systems and Controls, EPA, January 2000). Since the OAFE1500 accuracy of ±0.5% is AMCA certified, specifying engineers can be assured that ANSI/ASHRAE Standard 62.1 will
be met and that “returns due to improved air quality” may be gained.
Use of the OAFE-1500 can reduce HVAC operating costs and potential liability resulting from indoor air quality problems. The EPA further reports that, “the energy required to run the HVAC system constitutes about half of a buildings’ energy cost. Since energy efficiency can reduce operating costs and because the burning of fossil fuels is a major source of green house gasses, energy efficiency has become an important concern to the building industry and the promotion of efficient energy utilization has become a matter of public policy.” Refer to the OAFE-1500 technical data sheet for detailed information on product features, specifications, AMCA test results, dimensions, installation guidelines, and ordering information.
U.S. Green Building Council LEED® Green Building Rating System The Leadership in Energy and Environmental Design (LEED)® program objective is to encourage the design and construction of buildings that have little or no negative impact on occupants and the environment. The LEED® Green Building Rating System is based on a series of prerequisites and credits. The OAFE-1500 can be used to fulfill Indoor Environmental Quality (EQ) Credit 1: Outdoor Air Delivery Monitoring for non-densely occupied spaces. EQ Credit 1 requirements state, “For each mechanical ventilation system serving nondensely occupied spaces, provide a direct outdoor airflow measurement device capable of measuring the minimum outdoor airflow rate with an accuracy of plus or minus 15% of the design
2
minimum outdoor air rate, as defined by ASHRAE 62.1-2004.” Because of the exceptional accuracy of the OAFE-1500 it can also be used to minimize the additional energy consumption associated with higher ventilation rates (30% above the minimum rates) on projects seeking to obtain 1 point for EQ Credit 2: Increased Ventilation and on projects seeking to obtain 1-10 points for Energy and Atmosphere (EA) Credit 1: Optimize Energy Performance. In addition, the OAFE-1500 can be used to measure the required air volume (14,000 cu.ft. of outdoor air per sq. ft. of floor area) during building flush-out on projects seeking to obtain to obtain 1 point for EQ Credit 3.2: Construction IAQ Management Plan.
Energy Cost Savings Based on Accuracy The below tables show the yearly and 10-year energy cost savings due to the higher accuracy (0.5%) of the OAFE-1500 in comparison with the 15% accuracy required for LEED® EQ Credit 1 and the reported accuracies of competitor products. Based on the yearly energy cost savings, the OAFE-1500 capital cost could potentially be returned within the first year of operation and the return on investment is significant over a period of 10 years.

About PCI Primary Sensors
P
aragon Controls Incorporated (PCI) Primary Sensing Elements are designed for use in HVAC airside systems or industrial process control loops. They provide output signals readily convertible to air velocity, air volume, and differential pressures by devices such as indicating meters, transducers and controllers to meet the needs of all commercial and most industrial applications. PCI has been designing and manufacturing primary sensing elements since 1984, and they are now installed worldwide as a part of systems requiring continuous signals for HVAC or industrial automatic control, alarming, and process indication. All PCI Primary Sensing Elements are multi-point self-averaging devices. The output of the duct-mounted FE-1000 & 2000 series Primary Flow Measuring Elements is differential (velocity) pressure used to indicate airflow quantity at the point of measurement. PE-5000, 6000, 7000 & 8000 Series Primary Pressure Measuring Elements are duct or space mounted, and their output signals are the actual static pressures at the element locations. The accuracy of PCI’s families of FE & PE primary sensing elements has been independently qualified in accordance with the Figure 7 testing procedure of ANSI/AMCA Standard 210-85. However, it is more important to note that the stated accuracy of all PCI devices is constantly being field-validated by independent test and balance firms. Their Balance Reports document conformance to specification and confirm the superior operating performance of PCI commissioned systems.

Airflow Measurements
Operating Principles of FE and PE Series Sensing Elements The FE-1000 Series units are aerodynamic head devices which generate a differential (velocity) pressure output signal. The FE-1000 Series output is similar to that of an orifice plate, venturi, flow nozzle, or other head-producing primary elements, in that the differential pressure produced by these devices is related to the air quantity passing through the measurement plane. The basic design of the flow sensing element is a “cylindrical tube within a cylindrical tube” that permits the simultaneous measurement of both impact (total) pressure and static pressure. The total and static sensing port design eliminates the need for air straightening based on a known pressure distribution over a cylindrical surface and the incorporation of multiple impact (total) and static pressure sensing ports strategically located along its length provide comprehensive averaging of the velocity variations within the duct. The inner tube is an isolated chamber serving as a manifold for the impact (total) pressure sensing ports. The pressure within this manifold is influenced by the internal movement of air between the multiple ports that occurs because of their pressure differences. Similarly, the outer tube is an isolated chamber serving as a manifold for the static pressure sensing ports. The offset static sensing ports are located at the critical angle of the cylinder’s surface where there is no influence of dynamic (velocity) pressure when the element is inserted perpendicular to flow.
4
The static port design of the FE-1000 Series permits flow-angle variations of up to ±20˚ to occur without affecting the output value due to the linear characteristic of this portion of the pressure distribution curve. As the flow-angle changes from nominal, one static port is exposed to a higher pressure and the other static port is exposed to a lower pressure of equal value. The pressure within each manifold is sent through signal ports to become the output source of FE-1000 Series units. Total and static pressure outputs are transmitted through interconnecting tubing as primary input signals to a differential pressure measurement device (gauge, transmitter, etc.) for flow indication, alarming, data logging and/or feedback control purposes. The PE-5000 Series ductmounted Primary Pressure Sensing Elements are similar to FE elements but are furnished with static pressure ports only. The cross-sectional views shown in the adjacent figures identify the distribution of pressure around the cylindrical surface of the FE-1000 Series flow sensors in a moving stream of air or gas. These figures illustrate the innovative “Double-Hollow” FE-1000 Series design, the implementation of existing pressure measurement fundamentals and the ability of the flow sensing elements to measure true air velocity in moderately turbulent flow conditions. Multiple FE-1000 Series elements are required for most applications. Application and configuration tables are found in the Data Sheets of the individual FE-1000 Series airflow sensing products, and were developed to comply with the guidelines for Pitot-tube traversing of air ducts as published in the ASHRAE Fundamentals Handbook.

Pressure distribution on the surface of a FE-1000 Series unit when inserted nominal to the direction of flow. The impact (total) pressure sensing port is located in the center of the positive pressure portion of the cylinders surface. The static pressure sensing ports are located in the same plane and separated by about twice the critical angle, and one is centered in each of the two neutral pressure portions of the cylinder’s surface.

The impact (total) pressure port remains within the positive pressure portion of the cylinders surface. The effect of one static sensing port entering into the positive portion of the cylinders surface is offset by the other static sensing port entering into an equally negative portion of the cylinders surface.
The Model FE-1000 air flow sensor is available in (from left to right) stainless steel, aluminum, or PVC.
FE-1000 Airflow Sensing Elements Model FE-1000 units are primary airflow sensing elements designed for quick and easy installation through small cutouts in new or existing ductwork. They are true value-added products ideal for retrofitting (upgrading) existing systems with flow measurement capability. They are cost-effective replacements of failed or unreliable existing airflow sensing devices, and a design consideration for new systems and for applications requiring frequent sensor inspection and cleaning. Multiple FE-1000 elements are required for proper duct traversing in most applications, and their external total (high) and static (low) output ports are then field-manifolded for a single high and low connection. Each element is furnished with mounting hardware, sealing gaskets and signal connection fittings. Application information for circular, rectangular, and oval duct configurations is included in the FE-1000 Data Sheets. Standard construction is anodized aluminum that is suitable for most applications. FE-1000 units are optionally available in Type 1 PVC plastic or Type 316 stainless steel for corrosive atmospheres and Type 316 stainless steel for high temperature air or gas.
FE-1050 Fan Inlet Airflow Sensing Elements The FE-1050 units are airflow sensor assemblies specifically designed for installation in the inlet cone(s) of centrifugal fans or inlet bell of vane-axial fans. The high velocities and predictable flow pattern of the air entering the fan assure measurement accuracy and excellent response during system turn-down conditions. Application of this unique method of fan capacity measurement is simple and eliminates the costly, often frustrating, engineering design time required to meet the minimum inlet and outlet requirements of a traditional airflow measuring station. FE-1050 units also provide a most economical means of total fan air volume measurement. Only two flow sensing elements are required per fan inlet compared to duct units that may require as many as six elements for a proper traverse, or as a worst case, a system requiring summing of multiple branch ducts.
FE-1050 units are provided as complete assemblies for each inlet of a specific fan model, and each assembly has two airflow sensing elements, pivot mounting hardware and signal connection fittings. Standard construction is anodized aluminum that is suitable for most applications. The units are also available in 316 stainless steel for corrosive or high temperature duty.

FE-1500 Airflow Measurement Stations Model FE-1500 airflow measuring stations consist of single or multiple FE-1000 air flow sensing element(s) factory-mounted and externallymanifolded in an 8 inch (200mm) deep, 16 gauge galvanized sheet metal casing. FE-1500 units are connected to new or existing ductwork by 90˚ flanges on the air entering and leaving sides of the casing. They are available in all sizes and shapes to match the duct, and casings are optionally available in aluminum or stainless steel or with corrosion resistant coatings. Units are also available with an aluminum honeycomb airflow straightening section for exceptionally high turbulent flow conditions.
FE-2000 Pitot Tube Airflow Measuring Stations Model FE-2000 units are airflow measuring stations consisting of a flanged casing as described for FE-1500 models plus an integral aluminum honeycomb airflow directionalizer/ straightener section and bullet-nose shaped static pressure sensors and total pressure impact sensors. The multiple total and static pressure sensors are internally manifolded for signal self-averaging, and the manifold pressures are carried in tubing to ports on the casing wall for external connection to indicating and/or control devices.

Air Pressure Measurements
PE-6000 & 7000 Space/Room Static Pressure Sensors
PE-5000 Duct Pressure Sensing Elements Model PE-5000 units are insertiontype primary duct pressure sensing elements designed as a traverse to achieve pressure signal accuracy and stability. In addition, the accuracy and low signal-to-noise ratio of the output is made possible by the placement of the multiple sensing ports along the length of the element as well as the averaging effect of the internal manifold. Installation costs are low; the units are simply installed through a small cutout in new or existing ductwork. Their low installed costs make them very economical for multiple branch VAV duct systems where indication and fan capacity control may be based on the lowest and thus most economical pressure of the multiple static pressure points.
Model PE-6000 and PE-7000 Space/Room Static Pressure Sensors are designed to eliminate signal error caused by ambient air turbulence created by occupant motion, operating equipment or air distribution devices. The output of these sensors is an exceptionally accurate and stable static pressure signal for laboratory, cleanroom, containment or isolation room differential pressure indication and/or control. The PE-6000 is a surface-mounted sensor and the PE-7000 is a flushmounted ceiling sensor. Standard construction for both units is brushed aluminum. PE-6000 and PE-7000 units are optionally available in Type 316 stainless steel.
PE-8000 Outdoor Pressure Sensing Elements Model PE-8000 Pressure Sensing Elements are designed to provide a true outdoor (atmospheric) pressure signal that is not affected by windinduced pressure envelopes. Their output may be used as a reference for interior building space pressure control. However, the use and location of atmospheric pressure sensors has been the subject of many studies, and all conclude (as does PCI) that their use should be minimized or avoided. Problems with varying wind directions and wind gusts are the main reasons for the negative conclusions. Standard construction is brushed aluminum. PE-8000 units are optionally available in Type 316 stainless steel.
Standard construction is anodized aluminum that is suitable for most applications. PE-5000 units are optionally available in Type PVC plastic or Type 316 stainless steel for corrosive atmospheres and Type 316 stainless steel for high temperature air or gas.

“Reference Accuracy” meaning zero instrument inaccuracy. These graphs are used as the basis for comparing real world inaccuracy. Graphic illustration of why a DDC system performance is greatly enhanced when utilizing an input from a quality airflow transmitter. This graph was created using data logged output values from a differential pressure transducer, the mathematical conversion of the differential pressure transducer output to airflow as interpreted by a DDC system, as well as the accurate and stable output of PCI’s airflow transducer.

The expected overall accuracy of the control loop can be determined utilizing the standard “square root of the sum of the squares” equation. When applying this equation for airflow control it is important to note that the stated accuracy for the differential pressure transducer is a value based on its’ full scale output range. Therefore, due to the square root conversion required to make this signal linear to flow, even greater error will occur as the airflow system turns down. Add to this the issue of “signal to noise error” and the resulting control system performance is typically unacceptable.

he accurate and stable control of airflow or static pressure is only possible when Specifying Engineers understand the importance of accuracy, application and product selection when specifying each of the control device to be utilized for a specific control loop. Airflow measurement and control is a three step process, requiring the selection and application of: 1. A primary measuring element; 2. Transducer; and 3. Loop controller. The focus of this section is on the need for quality airflow transducers in order to help assure that accurate control is achieved.

Expected accuracy from a properly specified and selected flow transmitter, having a maximum span of .25" water column and ±0.5% accuracy.
Expected accuracy from a typically selected flow transmitter, having a maximum span of 1.00" water column and ±1.0% accuracy.
The scenario utilized for the above two (2) sets of graphs is for a variable air volume control system in which the maximum design air velocity through the airflow measuring station is 2,000 feet per minute. The first set of graphs show excellent control accuracy when utilizing a transducer meeting the accuracy, span and signal conditioning performance specification required for airflow control. The second set of graphs exemplifies the cause
of many control system failures due to poor performance criteria being specified for the airflow transducer. The control contractor is only responsible to select and furnish a transducer which meets the specification. Therefore, the Specifying Engineer must issue a transducer performance specification that will meet the operational expectations of the airflow control system.

Differential Pressure & Flow Transducers
PCI’s transducer family
T
his brochure describes instruments that are “standalone” components of a complete control system. This is, they are mounted in their own separate enclosure and are usually wall-mounted. The same instruments can be combined into one enclosure which would be the control panel for an entire system or major subsystem. The four families of instruments covered herein are Series DPT Differential Pressure Transducers, Series FT Flow Transducers, Series FI Flow Indicators, and output signal conditioning modules.

Series DPT Differential Pressure Transducers
Series FT Flow Transducers
DPT Transducers measure pneumatic input differential pressure and converts that signal to a electronic analog output signal that is sent to a controller or indicating device. These transducers require a 24 VAC/VDC power input. DC output signal is carried on a twisted pair of wires.
FT Transducers are similar to the DPT Series except that both total and static pressure inputs are required. The difference between the two pressures is velocity pressure that is converted by the transducer to velocity (fpm) or with the duct area known, to airflow (cfm). The output is a electronic analog signal for use by a controller or indicator.
Features of each model are identified and described below.
period. The transducer resumes its real-time analog output response after zero calibration is complete.
PCI’s Variable Capacitance Pressure Transducers are simple and very reliable sensors designed for high accuracy measurement of low differential pressures. A lightweight, ultra-responsive stainless steel diaphragm and an insulated electrode form the variable capacitor. A unique electronic circuit detects the change in capacitance and produces a 4 to 20 mA DC current output signal linear to the measured differential pressure. The high level output signal, the excellent long term stability and the fast dynamic response of the PCI transducer makes it ideal for a wide range of commercial, industrial, laboratory and aerospace applications.
The Signal Scaling Circuit converts the differential pressure signal (static pressure, or velocity pressure converted to velocity in fpm or airflow in cfm) to a user-specified full scale value. The Digital Display shows the converted transducer output signal on a 0.5" high four-digit light-emitting diode (LED) which is door mounted for local monitoring capability. The Square Root Extractor Circuits are used in all flow transducers to conform the output to the square root curve of velocity vs. velocity pressure. This circuit is essential for signal accuracy when the output is made linear to velocity or airflow.
The Automatic Zeroing Circuit performs a zero calibration of the differential pressure transducer output at user-selected intervals. Uninterrupted control and/or indication is maintained at the last output value during the approximate two second calibration
The Analog Meter is a diaphragmactuated differential pressure gage directly connected through bulkhead fittings and tubing to the static pressure or airflow measuring element.
This provides a continuous and direct indication of the true measured value independent of the hydraulics or electronics of other control components, and thus provides a instant visual check on the system status. The meter is provided with either a dual scale (fpm and cfm) for airflow readings or a single scale in inches of water for pressure readings. The indicating scales may also be customized for a specific design need. Surface-mounted Steel Enclosures are used for housing the electronic circuit boards. The enclosures are manufactured to NEMA 12 specifications and have welded seams, external mounting feet and a solid neoprene cover gasket. The standard finish is grey polyurethane enamel over phosphatized and primed surface. Pressure connections are convenient bulkhead compression fittings suitable for 1⁄4" OD metallic or thermoplastic tubing. Electrical connections are made via a standard 1⁄2" electrical conduit connector.

Function Modules
PCI’s scaling and alarm modules
Control Function Modules PCI offers a number of function modules for signal transmission, input alarming and signal ramping. All of these modules include filtering and signal conditioning to reduce susceptibly to transients and noisy operating conditions. The Signal Transmitter provides dual DC signal outputs proportional to a DC input signal. This product is very useful for scaling signal levels from one amplitude to another, as well as for converting from voltage to current. The Alarm Module monitors a DC input signal and provides two sets of SPDT, 3 amp alarm relays, each having its’ own adjustable setpoint and integral LED to indicate the alarm status. The module can be supplied in either a HI/HI, HI/LOW, or LOW/LOW alarm configuration.
The Ramp Module produces a DC output signal over an adjustable time rate setting based on the closure of a external contact. This module has integral LED’s indicating that the ramp module’s output is at minimum, or has reached a maximum output state. The ramp module is very useful for establishing the gradual opening or closing of a control damper.
The E/P transducer is non-position sensitive nor is it susceptible to variations in instrument air. This is due to the integral pressure transducer utilized to monitor and control the devices final output value.
Electronic to Pneumatic Transducer This device is utilized on electronic/pneumatic control systems for converting a DC input signal into a proportional pneumatic output. The unique design of this transducer allows for field setting of the pneumatic output range, as well as manual setting of the devices output. PCI’s electronic to pneumatic transducer

Outdoor Airflow Measurement System Engineered for accuracy, applicability, durability and simplicity in HVAC air systems
Model OAFE-1500 Outdoor Airflow Measurement System DESCRIPTION The OAFE-1500 is an airflow measurement station with integral signal processor that is capable of producing an overall ±0.5% accuracy through the velocity range of 200 to 1,200 fpm and ±5% accuracy at 100 fpm.
Pictured with optional inlet bell, temperature sensor, and temperature transmitter
The airflow measurement station consists of multiple airflow elements, factory mounted and pre-piped in a casing designed for flanged connection to ductwork, control dampers, louvers, etc. An optional inlet bell is available for plenum applications. Standard materials consist of a G90 galvanized casing and 6063-T5 anodized aluminum flow sensors, suitable for most HVAC applications. The airflow averaging elements are head type devices, which generate a differential (velocity) pressure signal similar to the orifice, venture, and other head producing primary elements. The airflow measurement station is constructed so as to comply with ASHRAE Standard 111 for equal area traversing of an airflow measurement plane. Multiple elements are manifolded together for connection to the integral airflow signal processor.
The signal processor utilizes current state-of-the-art digital microprocessor technology capable of producing unequaled 20-bit (1,048,576 steps) A/D and 12 bit (4,096 steps) D/A signal conversion resolution. Having a twelve-point linearization capability, the signal processor can be field calibrated to accurately determine true airflow rates even when the primary airflow measurement stations do not meet their minimum installation requirements. The ultra low 0.04"w.c. differential pressure, 800 fpm full scale operating ranges and the auto zeroing function of the signal processor provides accurate airflow measurement down to 100 fpm. The signal processor accepts a temperature input signal for air temperature indication, temperature signal transmission for remote readout, and air density compensation for standard or actual airflow calculations. A password protected configuration menu provides quick and simple field configuration by authorized personnel. Field configuration of engineering units, process noise filtering, operating range, alarm set points, etc, are performed via user friendly menus and a six button touch pad. An optional temperature sensor and transmitter with 4 to 20mA output and temperature range of -30 to 130°F is available to provide the temperature input signal to the signal processor for air density compensation.

FOR DUCTED OUTDOOR AIR APPLICATIONS The elements may be installed in any duct configuration. However, the accuracy of the installation is dependent on the flow conditions in the duct. The minimum installation requirements for the elements based upon a uniform velocity profile approaching the duct disturbance for flow rates less than 2,500 fpm are shown below. These are not ideal locations. It is always best to locate the elements as far as possible from all duct disturbances, with upstream disturbances being the most critical consideration. ELBOWS FLOW

DESCRIPTION The FE-1050 is an airflow measuring element assembly specifically designed for installation in the inlet cone of centrifugal fans or inlet bell of vane-axial fans. The design of these primary elements provides a means of accurate measurement of fan capacity along with ease of installation. Each assembly is complete with two airflow measuring elements and pivot mounting hardware. The FE-1050 airflow averaging element assembly is a head type device, which generates a differential (velocity) pressure signal. The basic design is a “cylindrical tube within a cylindrical tube” creating independent chambers which permit the simultaneous measurement of both total pressure and static pressure. Multiple total and static pressure sensing ports (which are strategically located based on the known pressure distribution over a cylindrical surface) provide comprehensive averaging of the velocity variations. Each chamber is then connected to one side of a differential measurement device (gauge, transmitter, etc.) for flow measurement and indication purposes.

FE-1050 Application Guide To determine the proper quantity and size of FE-1050 assembly(s) required, follow the steps listed below: 1.
Determine the inlet diameter (12 inch minimum inlet diameter recommended) at the point where the elements will be mounted. The FE-1050 assembly is designed to be installed at the minimum inlet diameter of any fan inlet cone not obstructed by inlet vanes.
2.
One set of two elements is required for each inlet. Double inlet fans require two sets of two elements, which are manifolded together by instrument tubing external to the fan.
3.
Care should be taken to determine that drive motors, actuator arms, fan shafts, bearing supports, etc., do not directly interfere with the selected mounting location or sensing ports of the elements.

FE-1000 INSERTION TYPE AIRFLOW SENSING ELEMENT
DESCRIPTION The FE-1000 is an insertion type airflow sensing element designed for quick, easy installation through a small cutout in the existing ductwork. Where multiple elements are required for proper duct traversing, the output ports are manifolded together, external to the ductwork. Each element is furnished complete with mounting hardware and sealing gaskets. Standard aluminum elements also include all brass compression fittings required to manifold the elements together. The FE-1000 airflow sensing element is a head type device, which generates a differential (velocity) pressure signal similar to the orifice, venturi, and other head producing primary elements. The FE-1000 is constructed so that strategically located sensing ports (based on duct size) continually sample the total and static pressures, when inserted normal to flow. The total pressures sensed by the upstream ports are continually averaged within the element in an isolated chamber. The static sensing ports (located where the influence of the velocity head is zero) are averaged in a second isolation chamber. Each chamber is then connected to one side of a differential measurement device (gauge, transmitter, etc.) for flow measurement and indication purposes.
Features Low signal-to-noise ratio Multiple total and static pressure sensing ports along the length of the element Averaging internal manifold Insensitive to flow angle variations of as much as ±20o when faced in the normal direction of flow ±2% accuracy throughout the velocity rages of 100 fpm and over Standard construction is 6063-T5 aluminum with anodized finish Available in optional corrosive resistance materials including Type 316L stainless steel, Hastaloy, and Type 1 PVC Standard elements can be operated (in air) continuously in temperatures up to 350oF or intermittently in temperatures up to 400oF All elements can be operated in humidity ranges of 0 to 100% Standard elements have good salt air and mild acid resistance; excellent solvent and aromatic hydrocarbon resistance

FE-1000 Minimum Installation requirements The elements may be installed in most duct configuration. However, the accuracy of the installation is dependent on the flow conditions in the duct. The minimum installation requirements for the elements based upon a uniform velocity profile approaching the duct disturbance for flow rates less than 2,500 fpm are shown below. Elements should always be installed across the flow gradient. Add one duct diameter to the installation requirements shown below for each additional flow rate of 1,000 fpm. These are not ideal locations. It is always best to locate the elements as far as possible from all duct disturbances, with upstream disturbances being the most critical consideration. ELBOWS

FE-1500 DUCT MOUNTED AIRFLOW MEASURMENT STATION
DESCRIPTION The FE-1500 airflow measurement station consists of single or multiple airflow elements, factory mounted and pre-piped in a casing designed for flanged connection to the ductwork. Standard materials consist of a G90 galvanized casing and 6063-T5 anodized aluminum flow sensors, suitable for most HVAC applications. The airflow averaging element, utilized in the FE-1500, is a head type device, which generates a differential (velocity) pressure signal similar to the orifice, venturi, and other head producing primary elements. The FE-1500 is constructed so that strategically located sensing ports (based on duct size) continually sample the total and static pressures, when inserted normal to flow. The total pressures sensed by the upstream ports are continually averaged within the element in an isolated chamber. The static sensing ports (located where the influence of the velocity head is zero) are averaged in a second isolation chamber. Multiple elements are manifolded together for connection to a differential measurement device (gauge, transmitter, etc.) for flow measurement and indication purposes.

FE-1500 Minimum Installation requirements The elements may be installed in any duct configuration. However, the accuracy of the installation is dependent on the flow conditions in the duct. The minimum installation requirements for the elements based upon a uniform velocity profile approaching the duct disturbance for flow rates less than 2,500 fpm are shown below. Add one duct diameter to the installation requirements shown below for each additional flow rate of 1,000 fpm. These are not ideal locations. It is always best to locate the elements as far as possible from all duct disturbances, with upstream disturbances being the most critical consideration. ELBOWS

FE-1500-FX DUCT MOUNTED AIRFLOW MEASURMENT STATION
DESCRIPTION The FE-1500-FX airflow measurement station consists of single or multiple airflow elements, factory mounted and pre-piped in a casing designed for flanged connection to the ductwork. The station also incorporates an airflow straightening section using honeycomb having a ½ inch opening by 3 inch depth. Standard materials consist of a G90 galvanized casing, 6063-T5 anodized aluminum flow sensors, and 3003 aluminum airflow straightner. The FE-1500-FX airflow measurement station has been developed for use in duct systems having a highly turbulent condition at the point of measurement. The airflow averaging element, utilized in the FE-1500-FX, is a head type device, which generates a differential (velocity) pressure signal similar to the orifice, venturi, and other head producing primary elements. The FE-1500-FX is constructed so that strategically located sensing ports (based on duct size) continually sample the total and static pressures, when inserted normal to flow. The total pressures sensed by the upstream ports are continually averaged within the element in an isolated chamber. The static sensing ports (located where the influence of the velocity head is zero) are averaged in a second isolation chamber.

FE-1500-FX Minimum Installation requirements The elements may be installed in any duct configuration. However, the accuracy of the installation is dependent on the flow conditions in the duct. The minimum installation requirements for the elements based upon a uniform velocity profile approaching the duct disturbance for flow rates less than 2,500 fpm are shown below. Add one duct diameter to the installation requirements shown below for each additional flow rate of 1,000 fpm. These are not ideal locations. It is always best to locate the elements as far as possible from all duct disturbances, with upstream disturbances being the most critical consideration. ELBOWS

FE-1500-FX Specification Guide Airflow Measurement Stations 1.
Provide where indicated and/or scheduled airflow traverse elements capable of continuously monitoring the fan or duct air volumes they serve.
2.
Each element shall be designed and built to comply with, and provide results in accordance with, accepted practice for duct system traversing as defined in the ASHRAE Handbook of Fundamentals, AMCA publication #203, as well as the Industrial Ventilation Handbook. The number of sensing ports on each element, and the quantity of elements utilized at each installation, shall comply with ASHRAE Standard #111 for equal area duct traversing.
3.
Each element shall be of a dual integral chambered design. Each airflow measuring element shall contain multiple total and static pressure sensing ports placed along the leading edge of the cylinder. The static pressure chamber shall incorporate dual offset static taps on opposing sides of the averaging chamber, so as to be insensitive to flow angle variations of as much as ± 20 degrees in the approaching air stream.
4.
The airflow traverse elements shall be capable of producing steady, non-pulsating signals of true total and static pressure, with an accuracy of 2% of actual flow for operating velocities as low as 180 feet per minute (fpm). Signal amplifying sensors requiring flow correction (K factors) or field calibration are not acceptable.
5.
The airflow traverse elements shall not induce a measurable pressure drop, greater than 0.18 inch at 4,000 fpm. The units shall have a self-generated sound rating of less than NC40 and the sound level within the duct shall not be amplified, nor shall additional sound be generated.
6.
The probes shall be mounted in an eight inch deep, 16 gauge galvanized steel casing with 90 degree undrilled flanges, fabricated to the duct size, and shall contain multiple airflow traverse elements interconnected as herein before described.
7.
Where primary flow elements are located outside of the manufacturer’s published installation guidelines the manufacturer shall be consulted, and approve of any special configurations, such as air equalizers and/or additional and strategically placed measuring points, as may be required.
8.
Where the stations are installed in insulated ducts, the airflow passage of the station shall be the same size as the inside airflow dimension of the duct. Station flanges shall be sized to facilitate matching connecting ductwork.
Installation Considerations 1.
Primary flow elements shall be installed in strict accordance with the manufacture’s published requirements and with ASME guidelines effecting non-standard approach conditions. These elements serve as the primary signals for the airflow systems; it shall be the responsibility of the contractor to verify correct installation to assure that accurate primary signals are obtained.
2.
An identification label shall be placed on each unit casing listing model number, size, area, and specified airflow capacity.
Manufacturer 1.
Airflow measurement stations shall be Paragon Controls Inc. Model FE-1500-FX or equal as approved by the Engineer.
2.
Naming of a manufacturer does not automatically constitute acceptance of this standard product nor waive the responsibility of the manufacturer to comply totally with all requirements of the proceeding specification.

PE-5000 DUCT STATIC PRESSURE SENSING ELEMENT
DESCRIPTION Model PE-5000 units are insertion-type primary duct pressure sensing elements designed to achieve pressure signal accuracy and stability. The accuracy and low signal-to-noise ratio of the output is made possible by the placement of multiple sensing ports along the length of the element and the averaging effect of the internal manifold. Installation costs are low; the units are simply installed though a small cutout in new or existing ductwork. Their low installed costs make them very economical for multiple branch variable air volume (VAV) duct systems where indication and fan capacity control may be based on the lowest (most economical) pressure of the multiple static pressure points. Each element is furnished complete with mounting hardware, sealing gaskets, and signal connection fittings.
Features Low signal-to-noise ratio Multiple static pressure sensing ports along the length of the element Averaging internal manifold ±2% accuracy throughout the velocity rages of 100 fpm and over Standard construction is 6063-T5 aluminum with anodized finish Available in optional corrosive resistance materials including Type 316L stainless steel, Hastaloy, and Type 1 PVC Standard elements can be operated (in air) continuously in temperatures up to 350oF or intermittently in temperatures up to 400oF All types of elements can be operated in humidity ranges of 0 to 100% Standard elements have good salt air and mild acid resistance; excellent solvent and aromatic hydrocarbon resistance

PE-5000 Minimum Installation requirements The elements may be installed in any duct configuration. However, the accuracy of the installation is dependent on the flow conditions in the duct. The minimum installation requirements for the elements based upon a uniform velocity profile approaching the duct disturbance for flow rates less than 2,500 fpm are shown below. Add one duct diameter to the installation requirements shown below for each additional flow rate of 1,000 fpm. These are not ideal locations. It is always best to locate the elements as far as possible from all duct disturbances, with upstream disturbances being the most critical consideration. ELBOWS

MICROTRANSEQ DIFFERENTIAL PRESSURE AND AIRFLOW SIGNAL PROCESSOR
DESCRIPTION The MicroTransEQ signal processor utilizes current state-of-the-art digital microprocessor technology capable of producing overall ±0.1% accuracy with unequaled 24-bit (16,777,216 steps) A/D and 12 bit (4,096 steps) D/A signal conversion resolution. Having a twelve-point linearization capability, the MicroTransEQ can accurately determine true airflow rates even when the primary airflow measurement stations do not meet their minimum installation requirements. The ultra low 0.03"w.c. differential pressure (693 fpm) full scale operating range and the auto zeroing function of the MicroTransEQ provides accurate airflow measurement down to 100 fpm. The MicroTransEQ accepts a temperature input signal for air temperature indication and air density compensation for standard or actual airflow calculations. A password protected configuration menu provides quick and simple field configuration by authorized personnel. Field configuration of engineering units, process noise filtering, operating range, alarm set points, etc, are performed via user friendly menus and a six button touch pad.

FT & FIT-1001 SERIES AIR VOLUME/ VELOCITY TRANSDUCERS
DESCRIPTION FT & FIT-1001 Series transducers include Models FT-1001, FT-1001ZV, FIT-1001-D, FIT-1001-DZV, FIT-1001-M, and FIT-1001-MZV. FT & FIT-1001 Series are differential pressure transducers with a square root extractor, scaling multiplier, and output filter complete in a single package. The differential pressure transducer sensor operates on the capacitance principal and is capable of sensing ultra low differential (velocity) pressures. In the capacitance cell, a very lightweight, responsive diaphragm deflects a small amount when pressure is applied. This deflection results in a change in capacitance, which is then detected and processed electronically into an output signal linear to the velocity pressure. The electronic signal is then sent to the square root extractor/multiplier, which converts the velocity pressure signal into an analog output linear to velocity (fpm) or volume (cfm). The FIT Series includes local indication of the measured process air velocity and/or volume on either a 0.5 inch high 3-1/2 digit LCD display meter scaled in cfm (indicated by a “D” in the model number) or an independent front panel mounted magnehelic pressure gauge scaled in both cfm and fpm (indicated by a “M” in the model number). The independent magnehelic gauge readout allows for quick and immediate verification that the electronic transducer is operating effectively. An optional built-in three-way manual zeroing valve for ease of zero verification and calibration can also be furnished (indicated by a “ZV” in the model number). Each FT & FIT-1001 Series transducer is selected and factory calibrated to meet the design requirement of the flow measuring element being served.
