Kobold PPS paddle flow switch

Kobold PPS Paddle Flow Switch – Polysulfone Paddle

The Kobold PPS flow switch is a flow monitor for nominal pipe sizes greater than NW 32. Fluid flow (regardless of direction) deflects the paddle and over an eccentric moves a magnet holder fitted to a permanent magnet. The magnet actuates a non-contacting  dry reed switch embedded in the switching tube.

The paddle switch is available with N/O contact or N/C contact. The inlet and outlet pipe section should be approximately three times the nominal size of the piping. The flow monitor can be fitted in a standard T piece or reducing pipe. Ideally the flow monitor should be fitted in horizontal piping.
