Micro Brass Hall Water Flow Sensor for Water Heater As liquid passes through the flow sensor body, the magnetic rotor spins at a rate proportional to flow. This Causes a series of magnetic fields (the rotor vanes) to excite the Hall Effect sensor, producing a series of voltage pulses
Electronic water flow sensor FLW01001
Flow switch consists of magnetic core, rotating impeller, external casing and reed switch. Flow through the sensor activates the magnetic core to trigger switch action, with signal output.
