W131 Magneti Flow Switches

Magnetic flow switch can output ON or OFF signal accordingto the flow,it is an important component of the fluid flow control system.When the flow in thepipe is lager than start-up volume,magnetic valve core is forced by the flow pressure to move forward then trigger the reed switch.When the flow recrease to a volume smaller than start-up volume,magnetic valve core is forced back to theoriginal place by the repellant force ofthe reset magnet, the reed switch recovers.
