1 Inch Water Flow Sensor YF-G1 DN25 The YF-G1 water flow sensor is a device that is used to measure the flow rate of water. It consists of a turbine-type rotor that is placed in the water stream, and as the water flows past the rotor, it causes the rotor to spin. The sensor measures the speed of the rotor and converts it to a flow rate. The sensor has a digital output, which means that it provides a digital signal that can be read by a microcontroller or other host device. The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly, and a Hall sensor. It is installed on the water inlet end of the water heater to detect the water flow rate. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The device judges the size of the water flow and regulates it. Precautions for Use: Severe impact and chemical erosion are strictly prohibited. Throwing or collision is strictly prohibited. The temperature of the medium should not exceed 120 degrees If the water quality is too bad, please add a filter at the water inlet.

Water flow sensors are installed at the water source or in pipes to measure the rate of flow and calculate the amount of water that has passed through the pipe. Water flow is measured in liters per hour or cubic meters. Working: A water flow sensor is made up of a plastic valve through which water can pass. A water rotor and a hall effect sensor are used to sense and measure the flow of water. When water flows through the valve, it causes the rotor to rotate. The motor's speed can be changed as a result of this. The hall effect sensor calculates this change and outputs it as a pulse signal. The rate of flow of water can thus be measured. The Hall effect is the primary operating principle of this sensor. The rotation of the rotor induces a voltage difference in the conductor in this sensor, according to this principle. This induced voltage difference runs in the opposite direction of the electric current. When the moving fan rotates due to the flow of water, the rotor rotates, inducing a voltage. The hall effect sensor measures the induced voltage and displays it on the LCD display. read more : What is a Water Sensor?
