Series PDWS Paddlewheel Flow Sensor

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series PDWS Insertion Paddlewheel Flowmeters are designed for pipe size ranges from 1/2 to 8˝ with available materials of brass, stainless steel, PVC, and polypropylene.

The Series PDWS is intended to be used with the Series PWF, a wide variety of custom tee, saddle, or welded fittings that come in bronze, PVC, and stainless steel.

PRINCIPLE OF OPERATION
Uses the rotation of an impeller to measure flow. Liquid flow pushes the rotor and the rotation is detected by a Hall-effect sensor.

The output is a current sinking pulse signal that can be connected to the Series RTI to display flow rate and total, or to the Series BAT for a 4 to 20 mA analog signal.
Features
  • The bearings are made from ruby jewel to reduce the coefficient of friction and maintain high accuracy
  • PVC and polypropylene body material offers resistance against corrosive media
