Solution  2:Pipe Leakage system
Using high precision ultrasonic water meter in water supply main pipe.( its accuracy can reach R400. Even a small flow of water used by a single resident can be measured.) We needn't to go to the site to read the meter.only need read the total water consumption in the area from the manage computer.Then we can use the water consumption of the main pipeline to subtract the water consumption of the sub-pipeline to contirm the pipeline leakage and leakage rate in the area.STS_14
