Functions and advantages of IoT smart water meters

Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption, transmit water data and settle transactions. Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, this is a great improvement. In addition to recording and electronically displaying the water consumption, the smart water meter can also control the water consumption according to the agreement, and automatically complete the calculation of the water fee of the step water price. At the same time, it can perform the function of water data storage. The cellular-based Narrow Band Internet of Things (NB-IoT) smart water meter not only realizes intelligent remote metering control, but also has low power consumption, which greatly extends the service life of the water meter. From a higher level, the introduction of NB-IoT technology has brought revolutionary changes to smart water services. At present, the transformation of smart water meters and the monitoring of water source water quality are only in the digital stage. In the future, big data will be used to realize management based on smart models, and then form a smart water operation system and a smart water decision-making system. Eventually, it will move towards ecologicalization, that is, the expansion of cross-border business and the establishment of an ecosystem. NB-IoT technology has the characteristics of wide coverage, large connections, and low power consumption, so it has a wide range of application scenarios. In China, on average, every 5 people need a water meter. The amount of smart meter reading data connection is large and the amount of data transmitted each time is small. Therefore, the water meter can be said to be the most typical application field of NB-IoT technology. NB-IoT smart water services are mainly used in household meter reading and pipe network inspection. Compared with traditional methods, it can effectively avoid water loss caused by pipeline leakage and misreading and underreporting, and greatly reduce the operating costs of water companies; Furthermore, it provides more targeted dynamic management and analyzes the water consumption habits of different groups, so as to guide the construction and transformation of water supply network more scientifically and reasonably. The construction of NB-IoT smart water affairs has promoted the process of smart construction of urban infrastructure and improved the overall water cycle management efficiency of the city.
