Water Flow Sensor YF-S403 Flowmeter S403 Hall Flow Sensor 3/4 Inch Water Control Fluid Flow Sensor Switch

Product Description

3/4 inch water flow sensor YF-S403 is mainly composed of plastic valve body, rotor assembly and Hall current sensor. This flow sensor can be used for precise flow measurement. Installed at the hot water inlet to detect water flow. As water passes through the flow rotor assembly, the magnetic rotor spins at a speed that varies with the flow rate. The Hall current sensor outputs a corresponding pulse signal to feed back to the controller, and the controller controls the flow. It can be used in water heaters, credit card machines, automatic water vending machines, and flow measuring devices. 3/4 Inch Water Flow Sensor - YF-S403 Features: - Light weight, small size, easy to install.
