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.

*F(Hz)= 21*flow rate(Q)(l/min)
*Error:±5% for both formula;
Rated: DC5V for regular version: output high level 4.5V and above; low level 0.5V and below
Rated: DC24V for regular version: output high level 23.5V and above; low level 0.5V and below
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.
