Voice Recorder Accessories -Water Flow Sensor Generic Brand Highlights Water Flow Sensor The water flow sensor is mainly made of a plastic valve body, a rotor assembly and a a Hall current sensor. It is installed in the hot water inlet end to detect water flow. When water passes through the flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall current sensor outputs the corresponding pulse Signal and back to the controller, then the controller will control the flow. Can be used for water heaters, credit card dispensers, water vending machines, flow metering devices. Features: Light weight, easy to install Durable and portable. Gasket with the upper and lower strength structure never leaks.
