NB-IOT gas meter is a gas meter management system based on the communication between the Narrow Band Internet of Thing and the management center. The system can realize the functions of remote meter reading, remote valve control, remote charging and payment and remote fault detection without intermediate equipment such as collector and concentrator.
Usage and Feature
1.Communication mode: adopt the emerging NB-IoT network technology, wide coverage, mass connection, low power consumption, low cost.
2.Micro power technology: using ultra-low power microprocessor and timing detection technology.
3.High performance valve technology: built-in valves, high reliability.
4.Flexible billing: meter terminal billing or central billing can be set; Support real-time pricing/price adjustment.
5.Anti-strong electric and strong magnetic attack technology: when the external strong electric and strong magnetic attack, the gas meter will automatically close the valve and upload the alarm.
