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 wire 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 beinstalled after a filter.
3. The flow sensor installation has to avoid strong vibration and shaking of the environment, so as not to affect the sensor's measurement accuracy.
