Overview
Engineered for space-constrained installations, the U-GR3 smart ultrasonic gas meter delivers accurate measurement across a wide flow range of 0.016 to 10 m³/h. Its solid-state design ensures long-term stability, while integrated IoT connectivity enables real-time leak detection, pressure anomaly alerts, and tamper notifications. When abnormal conditions are detected, the built-in valve automatically shuts off and sends instant alarms to the cloud platform for immediate response.
