This product is light and handy in appearance, small in size, and easy to install. 2.There is a stainless steel shaft inside the impeller, which is always wear-resistant. 3.The sealing ring adopts the structure of upper and lower force and never leaks. 4. The Hall element is imported from Germany and is encapsulated with potting glue to prevent water ingress and never age. 5. All raw materials meet ROHS testing standards Product introduction: The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor. It is installed at 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. Vertical installation, the inclination does not exceed 5 degrees. The temperature of the medium should not exceed 1200C. Output waveform: Square wave NPN pulse signal Lead wire method: 1 Red IN to positive 2 Yellow OUT signal output line 3 Black GND connect to negative YF-S201 Frequency: F=7.5*Q(L\/Min) Error:  ±2% Voltage: 3.5-24VDC, current cannot exceed 10mA, 450 pulses will be output after flowing one liter of water That is, frequency calculation = constant 7.5 * unit flow rate (L\/min) * time (seconds) Flow range: 1-30L\/min technical parameter Scope of application: suitable for water heaters, credit card machines, automatic water vending machines, and other flow metering equipment! 1. Minimum rated working voltage: DC4.5 5V-24V 2. Maximum working current: 15 mA (DC 5V) 3.
