Precision Flow™ Air Velocity Transmitters directly monitor gas mass flow rates of free air flows or single point flows in pipes, ducts and stacks. The 4 to 20 mA output signal is linearly proportional to gas mass velocity without additional compensation needed for pressure and temperature variations. The 304 SS insertion probe contains a velocity sensor to monitor mass flow and a temperature sensor to automatically correct for temperature changes. The probe is directly mounted to a NEMA 2 anodized aluminum enclosure. Popular models are calibrated for air.

APPLICATIONS
Heating, ventilation and air conditioning (HVAC); hood and gas cabinet monitoring; cleanroom and cleanbench face velocity monitoring.
