The biggest advantage of using NB tables is safety.

Gas meters have experienced the development of the first generation of ordinary meters (manual meter reading), the second generation of IC card meters, and the third generation of Internet of Things meters. The first and second generations of gas companies in the country are gradually being phased out; mainly the intelligence, safety, and informatization of Internet of Things meters will become the mainstream trend in the future with the progress of the times.

The biggest advantage of using NB tables is safety.

(1) The Internet of Things smart gas meter has the function of remotely closing the valve. The gas company can analyze the user's gas consumption status through the data sent back from the meter end. When the meter end has abnormal conditions such as large flow exceeding the limit, small flow and micro-leakage, etc., the Internet of Things gas meter can directly issue valve closing instructions to the meter through the management and control system, which provides a strong guarantee for realizing accurate measurement and improving the safety of gas consumption for civilian users.

(2) The smart Internet of Things gas meter has a self-inspection function. When abnormal flow, under voltage, arrears, failure events, etc. are detected, it will immediately report alarm information to the platform. The platform notifies the maintenance personnel to deal with the failure, and the maintenance personnel can choose to issue instructions remotely or perform on-site maintenance according to the abnormal records of the system.
