1. The Water Flow Sensor is light, nimble outline, small size and easy to install. The bearings used in the rotating part. All materials are in line with ROHS testing standards.
2. 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.
3. Three wire connection: Red for positive, black for negative, yellow for pulse signal.
5. Instantaneous Flow Pulse Characteristic F=4.0x Q(flow) +/-10%
6. The cumulative flow pulse conversion ratio 1L Water=234 pluse +/- 10%
