Series P3 Polypropylene Flow Switch

Brand: Dwyer Instruments, LLC

Fit almost any piping requirements with the Series P3 Polypropylene Flow Switch.

The basic piston design consists of a hermetically sealed SPST normally open reed switch.

Choose the inlet and outlet port to be 3/8" male NPT or 1/4" male "Quick Disconnect". 

Select a quick disconnect acetal adapter for straight through flow or with a shut off valve. The shut off valve will stop line flow when the adapter is removed from the switch. The flow will resume when the adapter is reconnected.

With many snap-on fittings to choose from, any flow application can integrate the P3 Flow Switch into the existing piping.
