CFS380P Series Piston Type Flow Switch

Plastic Flow Switch, Liquid Flow Rates from 0.25 GPM to 2 GPM

DESCRIPTION

This rugged inline flow switch offers the same superior performance to non-clogging as its metal cousin (CFS380). The fixed set point and simple design make it a dependable switch.

The CFS-380P is an ideal choice for coolant applications requiring reliable flow detection in HVAC, semiconductor, welding, medical and other industries. 1/4" quick disconnect units have a host of snap-on mating adapters to fit most piping requirements.

Acetal Adapters for 1/4" Quick Disconnect 
Male Tube Fitting Units (180°F max.)
These adapters are available with or without an integral 
shut-off valve. The shut-off valve will stop line flow 
when the adapter is removed from the unit. Flow resumes 
when connected.
