To sense the flow change in the liquid lines as so to protect equipment against damage which could be caused by flow stopping in the pipeline. Liquid flow either exceeds or drops below the set flow rate.
Allowed Liquids Temperature:0ºC~120ºC.
Set Flow Rate can be adjusted according to different flow requirement.
SPDT micro switch ensures the quick action and guarantee the transient of the switch.

 Flow switch is used to sense the flow rate of liquid in the pipe line, when the flow rate reaches the setting point, it turns off(or turn on) to protect the torrential flow.
