The AV-FP range of economical airflow sensors sense differential (velocity) pressure of VAV units and other locations in main or branch ducts. Four different lengths allow the selection of the sensor to yield accurate readings on terminal unit inlet diameters from 100mm to 500mm.
The sensor operates by measuring the velocity pressure using a differential pressure transmitter such as the PTH-3202.
Mounting: Integral flange with gasket.
Connections: ¼” nipples for ⅜” OD polyethylene tubing.
Ambient: 0°C to 50°C
