1. Product description:
Infinity modular smart gas meter complies with smart meter design specifications of European Union, Russian Federation, China, etc..
Adhering to the modular design philosophy, the communication module is completely separated from the smart controller of the meter, and different types of communication modules can be changed on site anytime.
The design adapts to the rapid revolution of communication technologies and brings long- term, stable and valuable services to gas companies.
2. Features:
2.1 Various replaceable modules:
One base meter fits various replaceable communication modules;
Available GPRS, NB-IoT, LoRaWAN, sigfox, etc.
Easy installation without dismounting the meter or upgrading meter firmware
IoT platform available to accommodate meters with multiple communication media
2.2 Efficient safety protection:
Gas using safety detection and reverse flow detection;
Overflow detection;
Valve control available with multiple control logic.
