       The application of Nb IOT intelligent water meter solves the contradiction between supply and demand of urban water, and has good performance in solving the leakage rate of water supply and promoting urban water saving. First of all, look at the current problems of urban water supply.

       In the past decade, China's urban water use population has increased by 75%. The contradiction between urban water supply and demand has become one of the key factors restricting the sustainable development of cities. Therefore, since the action plan for water pollution prevention and control in 2015, the state began to intensively issue a series of policies to vigorously promote urban water conservation.
 
      Among them, the guide to urban water conservation issued in December 2016 clearly proposed that the water leakage control project should be the key content of urban water conservation transformation.
 
       It is understood that the national average leakage rate is about 30%, that is to say, for every 100 tons of water output by water supply companies, about 30 tons are leaked in the water supply process. In developed countries such as Europe and America, the figure is 8% - 10%. This is not only related to the aging of some urban water supply pipelines, but also related to the backward leak detection methods. "Most of them are the masters of water supply companies who hold the acoustic leak detector to listen along the water supply pipeline. Whether they can hear accurately depends on the experience of the masters. Sometimes the water even broke the road, and the water company knew that the pipe had burst.
 
       After the large-scale application of Nb IOT intelligent water surface, this problem has been effectively solved.

       Advantages of Nb IOT intelligent water meter. In the production process of water meter, Nb IOT module is directly integrated into the water meter, and network service is provided by the operator to solve the problem of difficult maintenance of wireless network of water company. At the same time, standard communication protocol makes the preparation of water meter flexible. By using flat network structure, the cost of adjustment and transformation of intermediate network is saved, there is no problem of line aging transformation, and the wiring engineering is reduced, which makes the comprehensive transformation cost of Nb IOT relatively lowest.
 
       Compared with GPRS, Nb IOT can achieve lower power consumption, stronger signal penetration, ensure the practicability of Nb IOT, establish a unified IOT platform, enable operators to undertake different IOT applications, shield the diversity of multi vendor protocols for water applications, and simplify the integration complexity of different vendors.
