1-60L/Min DC 3.5-24V Hall Effect Water Flow Sensor Counter Meter FS300A

The water flow sensor is mainly composed of plastic valve body, water flow rotor assembly and Hall sensor.
It is installed at the water inlet end of the water heater to detect the water inflow. When water passes through the water flow rotor assembly,
When the magnetic rotor rotates and the speed changes with the flow rate, the Hall sensor outputs corresponding pulses.
The signal is fed back to the controller, and the controller judges the water flow and adjusts it.
