Overview
Built for space‑constrained installations, the U‑GR3 smart ultrasonic gas meter offers accurate, maintenance‑free flow measurement from 0.016 to 10 m³/h. Its compact footprint fits easily into confined areas, while integrated IoT connectivity enables real‑time monitoring for gas leaks, pressure fluctuations, and tamper attempts. When an anomaly is detected, the internal valve closes automatically and instant cloud alerts are triggered - ensuring fast response with no human intervention required.
Main Features
1. Built-in shut-off valve for automated safety response
