13 Mar Smart Gas Meter
A smart gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas that provide accurate and secure monitoring of gas consumption. The smart gas meter transmits the measurement collection data, meter running status and other related information to the data center at regular intervals. After data analysis and analysis, interactions such as billing, settlement and issuing meter instructions are completed. Activities to realize smart metering, meter monitoring, abnormal alarms, remote/near-field recharge and payment, business consulting and other functions.
Communication solutions using “Wi-SUN”, “NB-IoT”, “LoRa” and “GPRS” provide complete coverage for the entire service area. Additionally, an optical port is installed to allow for physical access to meter, enabling changes in settings and data copying using a handheld unit (HHU).
