(Figure1)

The water flow switch T20-S(Figure1) is installed on the water pipe through series connection or parallel connection,It is used hydraulic pressure (air pressure) to drive magnetic induction and convey switch signals.
The water flow switch send on or off signal according to the liquid 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.
