Series FAFM Fan Inlet Air Flow Measuring Probe

REQUEST CALLBACK

Series FAFM Fan Inlet Air Flow Measuring Probe
Ask for Price

The Model FAFM Fan Inlet Air Flow Measuring Probes use evenly distributed total and static pressure measuring points to deliver an accurate measurement of flows in a fan inlet. The Air Flow Measuring Probes can be completely installed from outside of the fan making it ideal for when proper duct locations are unavailable. With its lightweight and durable construction in addition to its ease of installation, this product lends itself to being used in the HVAC industry.

There are two versions of the model FAFM fan inlet air flow probes to choose from depending on the depth of the fan inlet.

For fan inlets with depth less than 3-1/2" (8.89 cm): Please order a fan inlet probe with an "S" suffix. This probe has a diameter of .375" (.95 cm). It employs one total flow measuring tube and one static measuring tube. Each probe is covered with an extruded aluminum anodized coat. Each measuring tube has multiple sensing points.

For fan inlets with depth greater than 3-1/2" (8.89 cm): Please order a fan inlet probe with a "D" suffix. This probe has a diameter of 3-1/2" (8.89 cm). It employs extruded aluminum anodized coated probes with both total and static sensors on each tube.

Please Note: These are sold in sets of two. A set is necessary in order to ensure an accurate reading. No more than two air flow measurement probes will be needed to obtain an accurate reading.

Series FLST Duct Mounted Airflow Measurement Station

REQUEST CALLBACK

Series FLST Duct Mounted Airflow Measurement Station
Ask for Price

The Series FLST Airflow Measurement Station is easy to install -- simply connect the tubing to the station fittings, then to a differential pressure manometer, gage, transmitter or switch. Single or multiple airflow elements are factory mounted and pre-piped in a casing designed for flanged connection to the duct work. Standard materials consist of a G90 galvanized casing and 6063-T5 anodized aluminum flow sensors, suitable for most HVAC applications.

The Series FLST utilizes an airflow averaging element in a head-type device, generating a differential (velocity) pressure signal similar to the orifice, venturi, and other had producing primary elements. Strategically located sensing ports continually sample the total and static pressures when inserted normal to flow.

Total pressure sensed by the upstream ports are continually averaged within the airflow element in an isolated chamber. The static sensing ports are averaged in a second isolation chamber. Multiple elements are joined together for connection to a differential measurement device (gage, transmitter, etc.) for flow measurement and indication purposes.

Product Applications

  • Sensing fan, blower, and air handler output.
  • Determine duct flow rates in various zones in builiding.

Series MAFS Metal Averaging Flow Sensor
Ask for Price

The Series MAFS is ideal for use with Dwyer Instruments, Inc. precision air velocity gages, transmitters and switches. The Series MAFS uses evenly distributed total and static pressure measuring points to deliver an accurate measurement of flows in a duct. The blade profile provides enhanced performance with minimal flow disruption in the air stream. The air flow measuring probe can be completely installed from the outside of round or circular ducts, making it very quick to install. With its lightweight and durable construction, in addition to its ease of installation, the MAFS flow sensor lends itself superbly to applications in the HVAC industry.

Series PAFS-1000 Averaging Flow Sensor

REQUEST CALLBACK

Series PAFS-1000 Averaging Flow Sensor
Ask for Price

The Series PAFS-1000 Averaging Flow Sensor is ideal for sensing differential pressure in the inlet section of variable air volume terminal units and fan terminal units. Units can also be used to sense differential pressure at other locations in the main or branch duct systems.

The "H" port senses total pressure and the "L" port senses static pressure. The difference between these signals is the differential, or velocity pressure. For models PAFS-1002 to PAFS-1005, up to four sensing points and lengths of 3-5/32" to 9-29/32" (8.02 to 25.26 cm) to accommodate box size diameters of 4" to 16" (10.16 to 40.64 cm) are available. For models PAFS-1006 to PAFS -1011, up to 10 sensing points and lengths from 12-1/2" to 23-29/32" (31.75 to 60.72 cm) are available to accommodate appropriately sized duct dimensions.

Series STRA Duct Mounted Airflow Measurement Station

REQUEST CALLBACK

Series STRA Duct Mounted Airflow Measurement Station
Ask for Price

The Series STRA Airflow Measurement Station is easy to install -- simply connect the tubing to the station fittings, then to a differential pressure manometer, gage, transmitter or switch. Single or multiple airflow elements are factory mounted and pre-piped in a casing designed for flanged connection to the duct work. The Series STRA utilizes an airflow averaging element in a head-type device, generating a differential (velocity) pressure signal similar to the orifice, venturi, and other head producing primary elements. It has been developed with a honeycomb airflow straightening section for use in duct systems having highly turbulent conditions at the point of measurement. Strategically located sensing ports continually sample the total and static pressures when inserted normal to flow. Total pressures sensed by the upstream ports are continually averaged within the airflow element in an isolated chamber. The static sensing ports are averaged in a second isolation chamber. Multiple elements are joined together for connection to a differential measurement device (gage, transmitter, etc.) for flow measurement and indication purposes.
