The ICON Truflo FES flow switch is designed to detect liquid flow or no flow. With its completely plastic design the FES Flow Switch is ideal for corrosive liquid services, water treatment, waste treatment, liquid pumping, and process control systems. The FES switch has an SPST contact that can be wired to energize a device when liquid flow exceeds or drops below the set flow rate. The FES switch can control devices such as pumps, motorized valves, and alarm devices.

Construction features an all-plastic body (PP) with PP or PVC install fitting. It is suitable for pipe sizes from ½” to 8”. The adjustable paddle can be cut to length for specific pipe sizes. Maximum working pressure is 150 psi (10 bar). The Viton O-ring ensures compatibility with a wide range of media. The NEMA 4X enclosure provides protection in harsh environments. The switch comes with a DIN connector for easy electrical connection.
