Series PFH

Air Velocity Transmitter 0.2 Second Response, ±0.2% Repeatability

Series PFH Air Velocity Transmitters measure mass flow rate of air, nitrogen, or other non-combustible gases and delivers a 4-20 mA output signal directly proportional to gas mass velocity. Thermal sensor design provides accurate flow measurement without additional compensation needed for temperature and pressure variations. Easily install into pipes, ducts, or eternal flow streams for monitoring air flow in ventilation systems, aeration and drying air flow measurement, and test equipment flow sensing.
