OF05ZAT G1/2 DN15 Water Flow Sensor (Sea) Milk Gasoline Oil Diesel Flow Rate Sensor includes a plastic body housing, rotor / Oval gear, and a hall-effect sensor, PCB electronics board. When the water/liquid flows through the (oval gear) rotor, then the rotor is rolled. Its speed changes with different rates of flow. Then the magnetic rotor makes a reaction to the Hall sensor, the hall-effect sensor outputs the corresponding pulse signal.
