mini hall water flow sensor for coffee dispenser beverage dispenser
The water flow sensor mainly consists of a copper valve body, a water flow rotor component, and a Hall sensor.
Installed at the inlet end of the water heater, it is used to detect the inlet flow rate. When water passes through the water
flow rotor component, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs
corresponding pulse signals, which are fed back to the controller. The controller determines the size of the water flow rate and
adjusts it accordingly.
