NB-IoT intelligent gas meter
Product overview
NB-IoT intelligent gas meter is a gas metering instrument being developed independently by us with the domestic first-class level. It has the function of metering by itself and realizing the remote data transmission through NB-IoT, which the modern management level of the gas supply industry is improved, at the same time, it is convenient for users to use. It is composed of the base gas meter and the controller attached to the base gas meter. The base gas meter is selected by the well-known domestic manufacturer. the movement of the machine core is stable, the measuring accuracy is high, the working life is long, and the adaptive medium is more . The controller is designed and manufactured by ourselves. NB-IoT controller is used to ensure reliable data transmission.
Product advantages
1. Super low power consumption, longer battery life.
2. Super-strong coverage, signal coverage area is wide and deep, data transmission is stable.
3.High security, inherit 4G network security capabilities, support two-way authentication and strict encryption, ensure the safety of user data.
4.Stable and reliable, it can provide reliability access at the Telecom level.
5.Fully sealed design: all lines are sealed with high-performance sealant, without any exposed electrodes, the tightness is good.
6.Anti external electric and magnetic attack technology: when the external strong electric and magnetic attacks, the gas meter will automatically turn off the valve and upload the alarm instructions.
7.The system has large capacity, which can realize mass connection.
