The OMEGA™ FSW-160 is the newest heavy-duty line of flow switches. The switch is used to signal, start, or stop electronically operated equipment when flow or no-flow conditions occur.
Omega’s elastomeric sealing system is superior to the metal bellows that are subject to metal fatigue and corrosion. This seal system has been field-proven for over a decade. The FSW-160 can be used in pipes 1 inch and larger, with set-points as low as 4 GPM (15.2 LPM) to over 500 GPM (1893 LPM) in larger pipe sizes. The FSW160 uses a 15A SPDT micro switch that can control a 1/2 horsepower motor.
