Water Flow Switch Features: 1.sensitive contact 2.adjustable setting point

Product Introduction

FL Series 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.

The setting point could be adjusted according to different request of flow rate.

Suitable to water, oil glycol and other non-hazard liquid.
