Introduction:

The NB-IOT communication technology used in wireless IoT water meter applications enables real-time online data transmission, and remote monitoring of water usage data can be achieved by simply providing signals. The operation is simple, safe, and reliable. It adopts wide coverage network transmission technology, which enables easy access to water information for both dispersed areas and centralized water management, providing strong support for water supply units. It adopts a supporting system software platform for dataization, wireless communication, and meter integration, with a stable signal and continuous network connection, as well as meter reading and charging integrated into one. Installation and maintenance are more convenient, enabling various advanced functions such as remote control, massive data storage, tiered water pricing settings, and warning settings. Effectively promoting the construction and application of water big data cloud platforms is an ideal product for large water companies and major water users.
