High Performances DN20 Flow Water Flow 1-30L/min Water Flow Sensor Liquid Flowmeter for Water Heater

Features: The Water Flow Meter is a compact and easy to install meter. Its versatile designs allows for compatibility with various output modules, sensors, and remote transmitters. Designed for professionals and individuals alike, the Flow Meter is perfect for anyone who needs to accurately measure liquid flow rates. For use in various applications such as water heaters, water dispensers and more. Its compact size and easy installation make it suitable for a wide of applications. The water flow sensor is mainly composed of stainless body, water flow rotor assembly and Hall sensor installed in the water heater end, used to detect the flow, when the water through the water flow rotor assembly, the magnetic rotor rotate and speed changes with flow, Hall sensor output the corresponding pulse signal, feedback to controller, controller determines the size of the water flow for regulation.
