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 flows through the flow rotor assembly, the magnetic rotor will spin and the speed will vary with the flow. The Hall current sensor outputs a corresponding pulse signal to feed back to the controller, and the controller performs flow control. It can be used in water heaters, credit card machines, automatic water vending machines, and flow measuring devices. Features of 3/4 Inch Water Flow Sensor-YF-S403: -Light weight, small size, easy to install. Inlaid stainless steel impeller shaft, durable and wear-resistant. The sealing ring adopts the upper and lower force structure and never leaks. Nonviolent shock, chemical attack. Throwing or hitting is strictly prohibited. Vertical installation, the inclination should not exceed 5 degrees. The medium temperature should not exceed 120°C. Wiring: - Red: Positive (+) Yellow: Signal output.
