Commercial NB-10T IOT gas meter is used to measure the flow of gas in the pipeline, and at the same time, it has the functions of pre-collection of gas charges, ladder gas price, abnormal alarm, wireless communication and so on, which is an intelligent metering appliance applicable to modern gas management.
Commercial NB-10T IoT gas meter is integrated with NB-10T mobile communication module, which can realise remote wireless reading and control through the network architecture of NB-10T base station, core network, loT platform and application server.
The microcomputer inside the commercial NB-10T IOT gas meter automatically measures and stores gas consumption information, and can automatically detect the battery status of the gas meter, the gas meter operation status and other information, and the abnormal alarm is automatically reported; through the application server, it can realise remote tariff adjustment management, multi-rate management of ladder gas price, meter status and valve control, and many other management.
Key Technology
- Micro-power consumption technology: Adopting dormancy + timing detection technology, the average power consumption of the whole gas meter is less than 20uA, which greatly prolongs the service life of electric oil.
- Motor-valve technology: adopting motor-valve technology, reliable work, small pressure loss.
- Full sealing technology: all lines are sealed with high-performance potting adhesive, no leakage of electrodes, good sealing, to ensure the long-term stability of the circuit board in the humid, fumes and other harsh environments.
- Anti-external electric and magnetic attack technology: when detecting external strong electric and magnetic attack, the gas meter will automatically shut down the valve and alarm.
- NB-IoT wireless communication technology: adopting NB-10T technology based on cellular network communication, with lower power consumption, lower cost, wider coverage and massive connection.
- Microcomputer, microstorage technology: components are SMD package, high integration, to ensure stable and reliable product performance.
