YF-DN40 1.5″ Water Flow Sensor

YF-DN40 is a plastic body water flow sensor that contains a water rotor and a hall-effect sensor and is used for flow measurement for industrial application. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.

The output of the flow sensor is proportional to the water flow. The more the water flowing more are the pulses.
