Dwyer Series 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.
Flow Switch Sensors with an electrical contact output at a specific flow rate have different types of switches, which are paddle, thermal, piezo, and shuttle/piston.
Shuttle or piston flow switches are sensors with an electrical contact output at a specific flow rate. Models are used with oil, air, water and gases. Applications include oil flow control, low flow detection in cooling lines, and high pressure lubrication systems. Rugged construction and excellent chemical compatibility simplify flow/no flow detection.
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.
