Description<\/strong><\/h4>\n

The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor.<\/p>\n

It is installed at the water inlet end of the water heater to detect the influent flow rate as it passes through the water flow rotor assembly.<\/p>\n

The magnetic rotor rotates and the rotational speed changes with the flow rate and the Hall sensor outputs a corresponding pulse.<\/p>\n

The signal is fed back to the controller, and the controller determines the magnitude of the water flow and performs regulation.<\/p>\n

The sensor has three connections, two for power supply and one output (yellow).\u00a0Flow rate can be easily calculated, a pulse is approximately 2.25ml. If it is positioned and calibrated correctly, the accuracy of approximately\u00a010%.<\/span><\/p>\n

Calculation formula: Flow rate (l \/ min) = Frequency (Hz) \/7.5.<\/p>\n
