This flow sensor is installed in the hot water inlet end to detect water flow. The magnetic rotor rotates as water flows through the assembly, changing speed with the flow. The hall current sensor outputs pulse signals to the controller for flow control. Suitable for water heaters, credit card machines, water vending machines, and flow measurement devices.
