Flow Sensor

Product Details:

• Water flow sensor is mainly consists of plastic valve body, rotor assembly and hall current sensor. It is installed in the hot water inlet end for detecting water flow. When water through the flow rotor assembly, magnetic rotor will rotate and Speed will change as the flow change. Hall current sensor output corresponding pulse signal and feedback to controller, then the controller will control the flow. Can be used for water heaters, credit card machines, water vending machine, flow measurement device.

Product Details:

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.
