Dwyer Paddlewheel Flow Sensor PFT Series

Dwyer Paddlewheel Flow Sensor

 

The Dwyer PFT Series flow sensor is used to monitor liquid flow rates in pipes from 1-1/2″ to 40″ with just one size adjustable sensor. A square wave output signal is generated with frequency proportional to flow velocity. The PFT Series is ideal for monitoring water flow rates in irrigation systems and building automation cooling systems.
