YF-S301 Water Flow Sensor 0.3-10LPM
The hall effect water flow sensor is light, nimble outline, small size and easy to install. All materials are in line with SGS testing standards.
There is an integrated 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.
Stable, high temperature, low water pressure start.
Three wires connection: Red for positive, black for negative, yellow for pulse signal.

1. When magnetic material is close with the sensor, its characteristics may vary.
2. In order to avoid particle debris, the sensor must be installed after a filter.
3. The flow sensor can be installed in any direction. IT has to avoid strong vibrating and shaking environment, so as not to affect the accuracy.
