Dwyer Series P4 PPS Piston Flow Switch

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. 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 Series P4 PPS Flow Switch features a molded plastic construction for enhanced performance. Monitor liquids with fixed set points from 0.1 to 1.5 GPM. Choose normally open or normally closed SPST or SPDT hermetically sealed reed switch technology. The industrial switch features PPS (polyphenylene sulfide) R4 housing and piston, 316SS spring, fluoroelastomer O-ring and Epoxy. The inlet and outlet ports are 9/16"-18 UNF- 2B thread with optional 1/8" and 1/4" NPT or 1/2" barbed adapters.
