NB-IoT Remote Water Meter adopts a direct-read water meter as the measurement basis and connects via the NB-IoT narrowband cellular Internet of Things to achieve automatic remote meter reading of water usage. It effectively avoids door-to-door meter reading and features valve control functionality. This facilitates management departments in monitoring water usage, making remote meter reading and control more convenient and reliable. While saving manpower, material, and financial resources, it significantly enhances production efficiency and enables real-time tiered water pricing, M-BUS remote information transmission, large-capacity dual-site data storage, remote self-diagnosis of water meter operation status, remote monitoring, and more.

    Traditional smart water meter reading faces numerous challenges, such as difficulties in real-time monitoring, complex installation, high costs, and poor communication stability. With the emergence of NB-IoT narrowband Internet of Things technology, this situation can be fundamentally transformed. Based on the characteristics of NB-IoT technology—wide coverage, high reliability, high security, low cost, and low power consumption—it not only reduces meter reading costs in the smart water meter sector but also enables intelligent and big data-driven management of water meters, offering significant practical application value. Keywords: NB-IoT, water meter reading, Internet of Things, intelligence. In today's rapidly urbanizing society, the trend toward smarter and higher-rise residences continues to change people's lifestyles and habits. Because NB-IoT technology features wide coverage, high reliability, high security, low cost, and low power consumption, it can effectively address many meter reading issues in the smart water meter field. The NB-IoT smart water meter system primarily consists of water meters equipped with NB-IoT communication modules, NB-IoT communication base stations, an IoT cloud platform, a business server, and client management software. Each household is equipped with an NB-IoT smart water meter. Once activated, the smart water meter searches for nearby NB-IoT communication base stations and registers with the IoT cloud platform. The cloud platform then recognizes the device's data reporting and receiving capabilities. Water usage data from the smart water meter can be uploaded to the IoT cloud platform via the communication base station and can also receive control data messages from the cloud platform. Client management software retrieves real-time resident water usage data from the cloud platform through the business server, monitors each resident's real-time water consumption, and can implement real-time tiered pricing controls, customize data collection strategies for the business server, and push monthly water usage and billing information to residents.The application of NB-IoT technology in smart water meters offers convenience, safety, reliability, and ease of user management. Performance testing and analysis results indicate that the entire system operates well with stable performance, demonstrating broad market application prospects. In the near future, once NB-IoT water meter technology matures fully, it will represent a major transformation in the smart water meter industry.
