Overview
Installation teams save time with the U‑GR3's compact design - fewer tricky placements, fewer callbacks. For facility managers, it offers real‑time visibility into gas usage and system health across a 0.016 to 10 m³/h range with zero mechanical drift. The built‑in communication module pushes usage data and alerts directly to monitoring platforms. When leaks, pressure drops, or tampering occur, the valve closes automatically and cloud alarms are triggered - no site visit needed for verification.
