Series P2 flow switches are designed for both air and pure water applications, filter life monitoring, heat exchangers, and cooling applications. They feature a piston-type design that incorporates a hermetically sealed SPST magnetic reed switch.

The units are made of a Noryl housing and piston as well as a 316SS spring and stop pin. They have temperature limits of 0 to 212°F and pressure limits of 150 psi at 70°F and 50 psi at 212°F.

Series P2 flow switches have preset actuation points from 0.05 to 1 GPM for water and 25 CFH to 5 CFM for air. Eight models are available. Price is $35.
