Overview
The Viewshine U-GR4 Metric Gas Meter, as a new generation of fully electronic ultrasonic gas metering equipment, is equipped with time difference technology to accurately capture the time difference of ultrasonic propagation in the gas medium, achieving high-precision measurement. At the same time, it is equipped with advanced temperature and pressure compensation systems, which can quickly adapt to complex and changing working conditions, and can stably measure even in the face of extreme temperature or pressure fluctuations. Its design maximizes intelligence and flexibility, supporting multiple intelligent application modules such as remote data monitoring, deep data analysis, and automated billing, seamlessly integrating into various smart energy ecosystems; Adopting a structure without moving parts and a fully electronic measurement design, it eliminates mechanical wear and has a long service life. The integrated IoT connection function and shut-off valve make operation control more convenient. The ultra wide measurement range of 0.016m ³/h to 6m ³/h meets the diverse needs of commercial and residential areas. The sturdy and durable structure, combined with precise temperature compensation technology, redefines the accuracy of gas consumption monitoring and is a powerful tool for modern and efficient energy management.
