Far-Transmitting Diaphragm Gas Meter (NB-IoT)
The Far-Trans Membrane Gas Meter (NB-IoT) is built on a dedicated IoT network provided by a telecom operator and consists of a base meter, an intelligent control unit, and an NB-IoT communication module. This smart IoT membrane gas meter periodically transmits metering data, operational status, and other relevant information to a monitoring platform via the operator’s NB-IoT network. The platform’s data center then analyzes this information to perform tasks such as billing, settlement, real-time monitoring of meter status, and issuing commands directly to the meter—enabling features like intelligent metering, remote meter monitoring, online payment, and automated anomaly alerts.
Core Features
• Employs NB-IoT wireless communication for stable data transmission and wide signal coverage;
• Ultra-low power design for extended battery life;
• Addressing the challenges of difficult in-home meter readings and cumbersome payment/recharge processes for gas companies;
• Enables gas companies to remotely adjust prices and set tiered pricing systems;
• Supports remote valve control, allowing gas companies to remotely switch the gas meter’s shut-off valve on and off;
• Supports remote monitoring of meter fault status via the platform system;
• Supports multiple alert methods: on-meter LCD display, platform system alerts, SMS notifications, and mobile app message pushes, among others;
• Temperature compensation (optional);
• Pressure compensation (optional).
