Series P2 Flow Switch

Brand: Dwyer Instruments, LLC

The compact Series P2 Flow Switch utilizes a piston-type design for both air and pure water applications.

The switches have preset actuation points from 0.05 to 1.0 GPM for water and 25 CFH to 5 CFM for air.

The piston design incorporates a hermetically sealed SPST magnetic reed switch. 

The P2 is comprised of PPE & PS (polyphenylene ether and polystyrene) housing and piston and 316 Stainless Steel spring and stop pin.

All wetted parts are FDA compliant. Economical and superior design make this an excellent switch for pure water equipment, filter life monitoring, heat exchangers, and cooling applications.
