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.

• Low installation requirements: the base watch adopts a screw-wing large-diameter water meter, which is standard in size and easy to install;

• Convenient maintenance: With detachable design, simply replace the “NB-IOT Remote Module Cover” with the cover on the original mechanical watch, that is, upgrade to the NB-IOT type remote water meter, easy to disassemble and maintain. Convenient

• Long battery life: high-performance large-capacity battery in the remote transmission cover, ensuring wireless remote transmission work for ≥ years, and easy to replace;

• High measurement accuracy: the vertical screw base table is adopted, the starting flow is small, and the measurement accuracy is high;

• Timed reading function: regularly report water consumption data through the NB-IOT platform network every day;

• Battery voltage reading function: The battery voltage data is reported regularly every day through the NB-IOT platform network.
