Water Pipe Network Monitoring System

 箭头  The water pipe network is now strong

      With the intensification of urbanization in China, there are more and more water plants in big cities, and the water pipe network in urban areas is becoming more and more complex. In the past, a water plant managed one area, and some areas were often short of water, and some areas had excess surplus. In recent years, many cities have connected the water pipes of water plants to the grid, and implemented unified dispatching.

      With the long-term disrepair of some self-water pipe networks, the construction of urban public works destroys the pipe network, and often there is a water pipe rupture in a certain place that has not been managed for a long time.

 箭头  Demand for remote monitoring of water pipe network

       ⚪ It can know the pressure, water flow, and flow rate data of each pipe network in real time.

       ⚪ When a certain pipe network breaks, an alarm notification can be issued in tim

       ⚪ When the water volume of a certain pipe network is insufficient, it can alarm in time.

 箭头  Remote monitoring solution for water pipe network

      Hengyi Technology has developed a set of remote monitoring solutions for water pipe network, which includes monitoring platform, wireless transmission, and front-end high-precision water flow, water velocity, and water pressure sensors. Its block diagram is as follows
