Feature(may vary by option.)
●1. Water flow sensor mainly consists of brass valve body, water flow rotor assembly, constant current assembly and hole element
●2. Attach to the water inlet end of the water heater to detect the flow rate of inlet water. When water passes through the water flow rotor assembly, the magnetic rotor will rotate and the speed will change to linear according to the flow rate
●3. The hall sensor output the corresponding pulse signal and feedback to the controller
●4. The controller judge the size of the water flow
●5. Output signal: default output NPN pulse signal (if you need to connect to PLC, please contact customer service before ordering)
