ITEM NAME:DN40 Water Flow Sensor Flowmeter Hall Flow Sensor Control for 1.5"inch Pipe Water flow sensor is mainly consists of plastic valve body, rotor assembly and Hall Current Sensor.It is installed in the hot water inlet end for detecting water flow. When water through the flow rotor assembly, Magnetic rotor will rotate and Speed will change as the flow change. Hall Current sensor output corresponding pulse Signal and feedback to controller, then the controller will control the flow. Features: Lght weight, easy to install Inlaid with stainless steel impeller shaft, durable wearable. Seal Ring with the upper and lower force structure never leaks. Suitable for automatic gas water heaters Waterproof,Heat resistance,pressure resistance,cold resistance Specification: The lowest rated working voltage: DC 5V-24V Maximum operating current: 15 mA (DC 5V). Working voltage range: DC 5~18 v. Load capacity: ≠¤ 10 mA (DC 5V).
