NB IoT water meter relies on NB IoT narrowband technology for data transmission, with stable signal and continuous network. The advanced photoelectric sampling technology is adopted, and the measurement is accurate and reliable. Its advantage is remote control, including remote data, real-time monitoring, online recharge, and timed meter reading. It does not require manual meter reading and queuing for payment, and can effectively save the related expenses for meter reading and charging. The meter has the intensive data freezing function, which can be set by the NB IoT platform network to report every minute, hour, daily cycle, and 24-hour data according to the actual use of users. It supports online recharge and payment, and is compatible with three modes of handheld meter reading, regional meter reading, and automatic meter reading. The meter reading system is managed uniformly and the software platform is operated uniformly; The water meter has SMS reminder, which makes maintenance more convenient.
