CGW series ultrasonic gas meter is a new generation of high-tech gas meter. The ultrasonic gas meter obtains flow data through
ultrasonic flow channel, relies on NB-IoT network and cloud server to realize data exchange, and stores the collected meter
information to cloud database through cloud server. And through the development of backend WEB application client and mobile
client, it also enables further analysis, processing, management and application of gas data.
