Overview
The U-GR3 Ultrasonic Gas Meter is purpose-built for confined installation spaces. With a wide flow range of 0.016 to 10 m³/h, it combines high precision with robust data logging. The integrated IoT connectivity enables instant leak detection, pressure anomaly alerts, and tamper notifications - automatically activating the built-in valve and pushing real-time alarms to the cloud platform for immediate response.
Main Features
1. Built-in shut-off valve for automated safety response
2. Meter removal platform for easy maintenance
3. Gas leak monitoring with instant alerts
4. Wide measuring range (0.016–10 m³/h)
5. High accuracy with temperature & pressure compensation
6. Long-term data storage for usage tracking
