1. Product Description:
Meta smart gas meter is a series of products induding the NB-loT, Sigfox, and LoRaWAN communication technologies based smart gas meters. Based on the communication network, smart gas meters upload the collected measurement data, and meter operation status to the system, after data parsing, billing, accounting, and command interaction with the meter can be achieved at the data platform. Thereby smart metering, remote monitoring, abnormal condition alarms, multi-channel remote recharging and business processing can be realized in combination with the system via the NB-IoT/Sigfox/LoRaWAN network.
2. Features:
- Remote meter reading: Data transmission and analysis.
- Flexible billing: Tiered gas price, remote price adjustment.
- Alarm reminding: Low battery or low balance alarm,anti-tamper leakage or over flow alarm.
- Remote valve control: Two level valve authority control, abnormal valve alarm, linkage valve close alarm.
- Real-timeinteraction: Remote online billing, bill inguiry, remote recharge etc.via multiple social media channels.
- Communication module configurable in factory.
