Water Flow Switch

Operating Theory:
The flow switch is installed on the water pipe through series connection or parallel connection,It is used hydraulic pressure or air pressure) to drive magnetic induction and convey switch signals.
 
 The flow switch send on or off signal according to the flow volume, it is an important component of the fluid flow controls system.If  the  flow in the pipe is lager than start-up volume, the magnetic valve will be moved by  the force of  flow pressure, and then it  will trigger the reed switch that same sealed in the vavle and send the signal . When the flow volume reduce lower than the start-up volume,magnetic valve core will be forced back to theoriginal place by the reset spring in the vavle.


Application:
Gas and liquid  dual-use, it can be widely used in industrial automation, machinery and equipment, industrial compressed air, refrigeration HVAC fields. Flow switch magnet is not flowing waterways, normally used for sewage system pipe.
