Flow Switches

This family of small injection molded Polypropylene, Acetal, and PVDF Kynarf low sensing switches detect flow or no flow in a wide range of liquid and gas applications. Used to monitor coolant in lasers, activate water purification, turn on water system heaters, or sense dirty filters with SPST contacts that close on flow. Sized at approximately 1" x 5", they are available with 1/8" to 1/2" NPT and hosed connection fittings. ***(Be sure to order fittings with each switch, the inlet and outlet are 9/16-18 UNF thread)
