Model FE-1000 Airflow Sensing Element
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, venture, 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. Model FE-1000 Technical Data Sheet
Model FE-1050 Fan Inlet Airflow Sensing Element
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. Model FE-1050 Technical Data Sheet
Model FE-1500 Airflow Measurement Station
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, venture, 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.

Model FE-1500-FX Airflow Measurement Station with Integral Air Straightener
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 ˝ 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, venture, 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. Multiple elements are manifolded together for connection to a differential measurement device (gauge, transmitter, etc.) for flow measurement and indication purposes.

Model OAFE-1500 Outdoor Airflow Measurement System
To 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 airflow

and pre-piped in a casing designed for flanged The OAFE-1500 can be used to fulfill Leadership in Energy and Environmental Design (LEED)® Indoor Environmental Quality (EQ) Credit 1: Outdoor Air Delivery Monitoring for 1 point. EQ Credit 1 requirements state, “For each mechanical ventilation system serving non-densely 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 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 LEED® EQ Credit 2: Increased Ventilation and on projects seeking to obtain 1-10 points for LEED® 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 to obtain 1 point for LEED® EQ Credit 3.2: Construction IAQ Management Plan.

Model MFE-1000 & 3000 MicroFlow Air/Gas Flow Measuring Elements
The MFE-1000 & 3000 are differential pressure (head) devices specifically designed to provide continuous, accurate and reliable measurement of ultra low air/gas volumetric flow rates over a wide operating range. These flow sensing elements utilize the piezoid ring static pressure sensing technique, combined with a self-averaging total pressure sensing manifold. The MFE-3000 incorporates area reducing transitions on the entering and leaving ends to accelerate air velocity resulting in greater flow measurement accuracy. The output of the MFE-1000 & -3000 requires no correction (k) factor, and when actual air/gas density is determined the output of these devices provide accurate mass flow measurement.
