This type of water meter adopts a screw-wing impeller inside. The pressure loss is small and the measurement accuracy is high. The appearance is small and exquisite. The installation space is small. The vertical installation saves nearly half of the installation space compared with the conventional horizontal water meter. It is a far-reaching water meter with excellent overall performance. The built-in NB-IOT IoT module and chip have the advantages of stable network, convenient remote meter reading, remote remote control, etc. It is an IoT water meter that is worthy of preference by the water company and water resources management department.

一、Technical characteristics：
