Working principle of flow switch
SK-FS06,Flow switch
When the flow pushes the distance between the stainless steel baffle and the 3~5mm, the outer induction rod will sense the magnet trigger signal (ON), on the inner swinging rod. When the flow rate is reduced below the minimum flow rate, the baffle automatically resets the disconnecting signal (OFF).

Product detail
Stainless steel baffle
Use a 304 stainless steel baffle. When the baffle is too long, you can use scissors to cut the baffle to the length suitable for
you.
Buy 100 or more, and we can customize the shape and length of the baffle you want.you.
Conjoined copper head, no seam, no perforation, never leak, rest assured to use.
Permanent magnet.
Nd-Fe-B magnet, which can work at 180 ℃. When the dry Reed switch senses magnetism, it will output a signal.
Dry Reed Switch.
So that the switch has stable characteristics and extremely long service life. Compared with the general mechanical switch, the dry Reed has the advantages of simple structure, small size, high speed and long working life, and compared with the electronic switch, it has the characteristics of strong resistance to load impact and high reliability.
