Overview
Viewshine U-GR4 Sonic Gas Meter: Mission-Critical Precision with Proactive Protection
Engineered to meet the stringent demands of commercial kitchens, industrial plants, and multi-tenant energy systems, the Viewshine U-GR4 deploys ultrasonic metrology technology to deliver ±0.7% accuracy across an expansive 0.016-6m³/h dynamic range. This performance remains stable under fluctuating pressure/temperature conditions through real-time compensation algorithms.
The system's integrated IoT communication module enables continuous monitoring of consumption patterns, while its industrial-grade shut-off valve executes emergency flow termination within 0.8 seconds upon detecting leaks, pressure anomalies, or unauthorized usage – significantly mitigating operational risks.
Constructed with solid-state architecture, the meter eliminates all mechanical wear points inherent in diaphragm meters, extending service life by 300% while reducing maintenance interventions. Multi-layer electromagnetic shielding and IP68-rated enclosures ensure uninterrupted operation in electrically noisy environments, from commercial HVAC systems to industrial motor farms.
