Timed reporting and push-button trigger reporting
Highly secured with data communication authentication and dynamic encryption
Peak shift mechanism for channel congestion solving
Public network without network maintenance
Description
Based on the narrowband Internet of Things network, the NB-IoT Smart Gas Meter is an Internet of Things intelligent instrument with the remote electronic controller and NB communication module to realize smart metering, remote meter reading control, step pricing and real-time price adjustment.
Features
Timed reporting and push-button trigger reporting.
Highly secured with data communication authentication and dynamic encryption.
Peak shift mechanism for channel congestion solving.
Flexible setting for uploaded parameters with multiple upload modes by the day and the month.
Upload and display useful information, including meter number, IMEI number, alarm information, meter clock, accumulated gas consumption, balance, valve status, dry lithium battery voltage, RSRP value, SNR value and module firmware version etc;
Remote valve control function: early warning valve shutoff and forced valve shutdown, remote and local configuration mode, and infrared communication interface.
Signal enhancement function: reserved interface, when the wireless communication signal encounters blockage, the signal can be enhanced through external antenna, adding the IOT small station and other modes to ensure the stability of the uploaded data signal.
Data storage with 10 years monthly and 60 days daily gas consumption.
Convenient recharging: payment or recharge can be made through bank, mobile app, self-service terminal and other channels.
Public network without network maintenance.
Step pricing, real-time price adjustment and amount settlement.
Valve shut-off due to non-metering.
Error-correcting mechanism with high meter reading accuracy.
