129661 GEMS Sensors - FS-150 Series Flow Switch

The 129661 is a GEMS Sensors FS-150 Series flow switch set to trip normally open at no flow and close at a 1.0 GPM flow rate, used to confirm flow in pumps, cooling loops and process lines.

It connects via 1/2 inch NPT process ports with quick-connect electrical terminals, and is part of a size range spanning 0.5 to 5.0 GPM trip points in both normally open and normally closed at no-flow configurations.
