Viewshine U-GR4 Outside Gas Meter: Precision Intelligence for Commercial & Industrial Gas Management
The Viewshine U-GR4 Outside Gas Meter delivers high-precision measurement across an extended 0.016-6m³/h range, engineered for demanding commercial and industrial environments. Utilizing non-contact ultrasonic metrology technology, it achieves fully electronic measurement with a ±0.7% accuracy guarantee under complex conditions, enabled by dynamic temperature/pressure compensation algorithms. Its solid-state architecture eliminates mechanical wear risks, while anti-interference reinforcement ensures long-term operational stability.
Integrated IoT communication modules and intelligent shut-off valves enable real-time intervention for abnormal gas usage. The meter's smart application platform supports remote data monitoring, consumption pattern analytics, and automated billing – making it ideal for high-frequency energy scenarios like commercial kitchens and hotels.
