Product Description
Water flow switch is used for water circulation control, inlet and outlet control, water heating control, water pump switch control, solenoid valve on-off control or outlet power-off, outlet power-on control and other processes of electric water heaters, solar water heaters, air conditioners and other water systems. When a certain flow rate is reached, the water flow is converted into a switching electrical signal sensor device. When the fluid rushes towards the blade, the blade swings, changing the relative position of the magnet and the reed contactor, stimulating the contactor to close or disconnect. Once the fluid is interrupted, the blade returns to the starting position and the reed contactor is excited again. The mutual repulsion of the two magnets provides the force required for the flow switch to reset, and the contactor returns to its previous state. Product Parameters
