Overview

The Viewshine G4 Gas Meter represents the next evolution in ultrasonic gas measurement technology. Utilizing advanced time-difference ultrasonic detection, it precisely calculates gas flow by analyzing sound wave propagation delays, delivering unmatched metering accuracy. Equipped with real-time temperature & pressure compensation, it maintains reliable performance even under extreme environmental fluctuations.
Engineered for smart energy integration, it supports remote monitoring, data analytics, and automated billing, making it ideal for modern utility ecosystems. Its moving-part-free, fully electronic design ensures zero mechanical wear and extended lifespan. With built-in IoT connectivity and an integrated shut-off valve, control and automation are effortless. The ultra-wide flow range (0.016–6m³/h) caters to both residential and commercial applications, while robust construction and precision thermal compensation set new standards in gas measurement efficiency.
