NB IoT IoT valve controlled 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 advantages and features are remote control, including remote data, real-time monitoring, remote valve control, online recharge, timed meter reading, etc. It does not require manual meter reading and queuing for payment, and can effectively save relevant expenses for meter reading and charging. According to the actual use of the user, the system can set the minutes, hours, and daily reports through the NB-IOT platform network, and report 24-hour data. It supports online recharge and payment. The water meter has SMS reminders, which can control the water meter valve according to the water use and incentive charges. The product has the function of emergency valve opening. At the non communication window time, the valve can be opened for a period of time after simple local operation of the water meter button. Physical key design makes maintenance more convenient.
