NB-IOT gas meter adopts the most advanced narrowband cellular communication technique, with the advantages of network depth coverage, wide links, low power consumption and stable, reliable and safety communication.
1. Adopt industrial level NB-IOT module, SIM card adopts industrial level M2M IOT SIM card.
2. Adopt lithium battery, and battery life is more than 8 years, if the power failure, the data can be saved for 30 years.
3. Two online intervals can be set and real time meter reading can get during the online intervals.
4. Timing period data upload, can set the uploading interval, and the uploading data includes: the daily gas consumption of current month and last month, accumulated gas consumption, balance (gas quantity), and etc.
5. LCD display, real-time display of gas consumption, signal intensity, battery level and valve status, etc.
6. Remotely prepaid function, can support 5 tariffs 6 prices, bill calculaion mode can be set as monthly, quarterly or yearly.
7. Alarn function: being attcked, low battery, low balance, valve failure and overdue bill.
