Safety-Shutoff Gas Meter
By installing an "intelligent module," we enhance both software and hardware with advanced safety control features, enabling real-time monitoring of issues such as gas flow overload, abnormal flow rates, excessively low gas pressure, and prolonged constant-current operation timeouts—effectively creating a robust protective barrier to safeguard users' lives and property.
Core Features
• Safe gas usage: Monitored for anomalies such as flow rate, pressure, and temperature; in case of any irregularities, valves are promptly shut off and alerts are sent to the alarm platform. Gas usage is continuously tracked in real time, ensuring greater safety and peace of mind.
• Safety features: abnormal low flow, abnormal high flow, continuous flow, over- or under-pressure conditions, and excessive meter body temperature;
• Employs NB-IoT wireless communication for stable data transmission and wide signal coverage;
• Ultra-low power design for extended battery life; addressing the challenges gas companies face in conducting in-home meter readings and making bill payments and recharges easier.
• Enables gas companies to remotely adjust prices and set up 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 push, among others;
• Temperature and pressure compensation (optional).
