Watts FS10-C - Manual

Series FS10-C
Flow Switch
Sizes: For pipes 1" - 6" (25 – 150mm)
Series FS10-C Flow Switch provides accurate monitoring of
liquid flow in pipelines servicing water systems, heating systems,
air conditioning, and processing installations for industrial and
commercial applications. The flow switch is designed to act as
an automatic control or safety device for liquid flow. The single-
pole, double-throw switch can be wired to start or stop a motor
when a flow or no flow condition exists or activate an alarm
when flow is inadequate. The switch then turns off the alarm
when adequate flow is restored. Series FS10-C flow switches
install in tee in horizontal or vertical piping.
