This product has its own patented technology, and the patented technology name is “the impeller gravity balance device of large-diameter screw-wing water meter and its gravity balance method”. The base table is a vertical screw-wing ordinary water meter, and the NB-IOT intelligent remote transmission module is installed on the top to form a large-caliber intelligent remote water meter. The NB-IOT IoT network is used to realize the remote reading function of water meter usage data. Wide range, high precision, R=200. The technology is stable and reliable, and it is easy to disassemble and maintain after sale. Accurate measurement improves the economic benefits of water resources management and reduces water waste. It is applicable to the management and metering charges of large-capacity water meters such as enterprise users, supporting master tables, and specific users. It is the preferred water resource management department of the water resources management department to remotely manage water meters and large-caliber IoT water meters.
