Different business departments in the city and even between cities need to be effectively connected, and through intelligent data analysis, information integration and data mining, to better meet the needs of industrial development. Smart water services require large-scale accumulation of high-density, high-precision and high-value water data, and data collection capabilities are the basis for the perception of smart water services. In certain specific scenarios, such as monitoring water resource consumption in special industrial enterprises, the requirements for data collection and real-time performance are more stringent, requiring "real-time, complete and accurate collection of flow process curve data". Smart water meters are not only the most widely distributed basic data source in the water industry, but also an industry touchpoint closely related to the lives of ordinary people.
