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.
