YF-S201 High-Flow Water Meter – 1–30 L/min Range

Description

1. Working Voltage: 5 to 18V DC (min tested working voltage 4.5V).
2. Max current draw: 15mA @ 5V.
3. Working Flow Rate: 1 to 30 Liters/Minute.
4. Maximum water pressure: 2.0 MPa.
5. Flow rate pulse characteristics: Frequency (Hz) = 7.5 * Flow rate (L/min).

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.

This is YF-S201 Water Flow meter Measurement Sensor with 1-30Leter/min Flow Rate in black colour. This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There’s an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
