0.25-3.0 L/min OD 6mm Water Flow Sensor Hall Flow Meter Magnetic SwitchProduct Description SEN-HZ06S Water Flow Sensor, 6mm Quick Connector Self-Locking, Easy to Install, Hall Working Principle, Pulse Signal Output, Red is Positive, Black is Negative, Yellow is Pulse Signal, Can Be Used as Water Flow Switch, Food Grade POM Material, Can Be Used In Filter Manager, Direct drinking machine, water filter, coffee machine, energy water machine, beer machine, wine cooler, for mechanical equipment, laser equipment, toilet and so on. The pluse signal water flow sensor is widely used in industrial equipment, agricultural equipment and household electrical appliances in the future. It includes plastic housing body, water rotor and hall sensor, PCB electronics board. Our water flow sensors with POM materials can be used for water dispenser, water filter, coffee maker, wine cooler, beer machine, water machine liquid flow monitor, boiler, coffee machine, vending machine, water meter testing machine and so on. Working efficiency: when the water flows through the impeller, then the impeller is coiled, its speed changes with different flow speed. Then the magnetic rotor reacts to the hall sensor, the hall sensor outputs the corresponding pulse signal.
