Overview
Installation teams appreciate the U‑GR3's compact footprint - fewer tight spots to navigate, fewer return visits. Facility managers gain continuous visibility into gas consumption and system status across a 0.016–10 m³/h range, with no mechanical drift over time. The integrated communication module sends consumption data and alerts straight to monitoring platforms. In case of leaks, pressure fluctuations, or interference, the valve shuts automatically and cloud‑based alerts are raised - no site visit required for confirmation.
