Specification: Item Type: Water Flow Switch Model: FS-02 (G1 / 2) female/male thread Working Voltage: 0-48(VDC) Rated Current: 0.5(A) Rated Power: 70W Working Temperature: -40 ~ 120(℃) Applicable Medium: Water / oil Installation: Horizontal / vertical Material: 304 stainless steel Flow Size: >1.2L/Min Thread Size: Female/Male threads G1/2in Water Inlet and Outlet Diameter: φ11mm Size: Approx. 60 x 32 x 24mm / 2.4 x 1.3 x 0.9in The working principle of the water flow switch is that an upward lifting force lifts a magnetic valve core close to and drives a reed switch to generate a signal when the water flows. The advantage of the water flow switch is that the water pressure is low. When the magnetic ring inside the piston is pushed to the position of the reed switch, the reed switch generates a signal. Reed switch water flow switch has stable working performance and is widely used in various equipment. And some piston water flow switches can adjust the reed switch operating point to change the flow signal, so it is the first choice for various types of equipment.
