Overview
The Viewshine U-GR4 gas intelligent instrument can provide high-precision measurement in the range of 0.016-6m ³/h, designed specifically for demanding commercial and industrial environments. By utilizing non-contact ultrasonic measurement technology and dynamic temperature/pressure compensation algorithms, full electronic measurement has been achieved under complex conditions. Its solid-state architecture eliminates the risk of mechanical wear, while anti-interference reinforcement ensures long-term operational stability.
The integrated IoT communication module and intelligent shut-off valve can provide real-time intervention for abnormal gas usage. The intelligent application platform of this meter supports remote data monitoring, consumption mode analysis, and automatic billing, making it an ideal choice for outdoor high-frequency energy scenarios.
Main Features
1. Extended accuracy range: Measure gas flow rates from 0.016 to 6m ³/h with an accuracy of ± 0.7%.
2. Solid state reliability: Non contact ultrasonic technology+no moving parts=zero mechanical wear.
3. Real time security control: IoT enabled shut-off valves can immediately respond to abnormal usage.
4. Intelligent energy analysis: remote monitoring, consumption pattern analysis, and automatic billing functions.
5. Industrial grade elasticity: anti-interference design+dynamic temperature/pressure compensation, stable operation.
6. High frequency scene optimization: designed specifically for outdoor and high usage environments.
