SENS-MH-02 Temperature Conductivity Hall Flow Sensor Meter 6 Wires
this device is installed at the inlet end of various water equipment and is used to detect the inlet flow rate. When water is passing through
the rotor assembly, the magnetic rotor rotates and the rotational speed changes according to the flow rate. The hall sensor output
corresponds with the pulse signal , and feedback to the controller.
The main function of the controller is to measure cumulative flow and instantaneous flow; single quantitative and total quantitative analysis, and water temperature detection.
