DPFS Differential Pressure Flow Sensor

Brand: Kele

The Kele DPFS Series differential pressure flow sensor is the most economical way to sense airflow velocity in VAV ducts, and other small size branch ducts in HVac systems. 

The DPFS Series is available in 4 different lengths for flow sensing in duct sizes from 4" to 18" (10 to 46 cm) and can reliably sense velocities above 1,000 FPM (feet/minute) or 305 MPM (meters/minute).
