The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor.
It is installed at the water inlet of the water heater and is used to detect the influent flow when the water passes through the rotor assembly.
The magnetic rotor rotates and the rotation speed changes with the flow rate, and the Hall sensor outputs corresponding pulses
The signal is fed back to the controller, and the controller judges the size of the water flow for regulation.
Severe impact and chemical attack are strictly prohibited.
Do not throw or bump.
Vertical installation, the inclination does not exceed 5°.
The medium temperature should not exceed 1200℃
