The FES Series Flow Switch is designed to detect liquid Flow or Low / No Flow. The FES switch encompasses a SPST contact that can be wired to energize a device when liquid flow either exceeds or drops below the set flow rate.

The FES Series is an excellent choice for corrosive liquid services, water treatment, waste treatment, liquid pumping and process control systems.

The FES Flow Switch can control devices such as pumps, motorized valves and alarm devices.
