The gas meter consists of a base meter with built-in motor valve and an intelligent controller with NB-IoT communication module. With the linkage of the NB-IoT network and the background system, functions such as smart metering, remote monitoring, and air recharge can be realized.

By connecting to the NB-IoT wireless network platform, the following functions can be implemented:

• Data transfer to the cloud, data analysis. 

• Step gas price. 

• Alarm prompt: balance and power shortage alarm; tamper, leakage, overflow alarm. 

• Remote monitoring, intelligent control. 

• Remote control valve: two-stage valve authority control, valve anomaly alarm, alarm for alarm-linked valve closing. 

• Realizing remote payment and real-time interaction in combination with new media channels.
