The NB IoT water meter relies on the NB IoT narrowband technology for data transmission. The signal is stable and connected to the network. The advanced photoelectric sampling technology is used to make the measurement accurate and reliable. Its advantages are remote control, including remote data transmission, real-time monitoring, online recharging, regular meter reading, no need to queue up to pay fees manually, which can effectively save costs related to meter reading and charging. The meter has the function of intensive data freezing, which can be set to report every minute, hour and day through the NB IoT platform network according to the actual situation of users, and report 24-hour data. It is compatible with three modes of hand-held meter reading, regional meter reading and automatic meter reading.
