This flowmeter operates on the basis of the magnetic effect, it feeds at voltages between 5 and 18 V (DC) and is easy to use - it counts the pulses obtained at the output.
Description
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 end of the water heater to detect the influent flow rate as it passes through the water flow rotor assembly.
The magnetic rotor rotates and the rotational speed changes with the flow rate and the Hall sensor outputs a corresponding pulse.
The signal is fed back to the controller, and the controller determines the magnitude of the water flow and performs regulation.
The sensor has three connections, two for power supply and one output (yellow). Flow rate can be easily calculated, a pulse is approximately 2.25ml. If it is positioned and calibrated correctly, the accuracy of approximately 10%.
Calculation formula: Flow rate (l / min) = Frequency (Hz) /7.5.
