Remote Water Meter Reading System DMA-Tengyue Metering

Leakage & DMA (District Metering Area)

In the current situation of relative shortage of water resources and rising water supply cost, improving the management level of urban water supply network and reducing the leakage of pipe network system, especially the low differential rate of water supply production and sales, have become the focus of the water supply industry.

The difference rate of production and sales of Water supply refers to the ratio of the difference between water supply and sales to water supply. The difference rate of production and sales of water supply is a direct reflection of the economic benefits of the water supply industry, and it also indirectly reflects the situation of Non-revenue water in the water supply network, including leakage, and is the main indicator to measure the control level of leakage in the water supply network.

The main reasons for the high production and sales difference of the water supply network are as follows:
●  1) Pipe network leakage, including open leakage, dark leakage and background leakage caused by small corrosion in pipe joints and pipes (undetectable leakage)
●  2) Water meter measurement error or failed to collect water charge after meter measurement
●  3) Inability to measure water, illegal water use, and water theft

Therefore, the DMA system independently designed and developed by Tengyue can timely and effectively discover the leakage of pipe network, and illegal water use/theft, and repair it in time, thereby reducing the proportion of the difference between production and sales of the water supply pipe network, and greatly improving the economic benefits of the water company.

DMA system planning

DMA(District Metering Area) zoning metering management, by cutting off the pipe section or closing the valve on the pipe section, the pipe network is divided into several relatively independent areas, and in each area of the inlet and outlet pipes installed with data upload function of the bulk meter/flow meter, to realize the monitoring of the inflow flow of each area. At the same time, household water meters with data upload functions (GPRS/NB-IOT smart water meters, etc.) are installed in other water points (end users) in the region to monitor the flow of water points in each region.
