Overview
Viewshine Residential Ultrasonic Gas Meter is engineered for space-constrained applications, seamlessly fitting into compact settings such as narrow meter cabinets. Engineered with innovative ultrasonic technology, it delivers highly accurate and reliable measurement across a stable range of 0.016–10 m³/h.
This Smart Gas Meter is also an active safety guardian: once abnormal conditions (pressure fluctuations/leakage/tempering) are detected, the meter automatically triggers built-in valve shutoff and simultaneously alerts the users via IoT platform with real-time incident notifications.
Its fully electronic, mechanical-movement-free construction ensures long-term durability and stable, dependable performance-providing users with a gas measurement solution they can trust.
Main Features

1.Strong environmental protection performance
Specialized structural design to adapt to harsh environments such as humidity and dust, ensuring stable operation
2.Low power consumption operation mode
Lithium battery power supply realizes long-term use without frequent replacement, reducing maintenance costs
3.Intelligent fault self-diagnosis
Built-in sensors detect abnormal conditions (such as blockage) and trigger timely alarm prompts, facilitating troubleshooting
4.Anti-tampering protection mechanism
Multi-layer verification technology prevents illegal modification of metering data, ensuring metering authenticity
5.Gas pressure adaptive adjustment
Dynamic response to different gas pressure fluctuations in pipelines, maintaining consistent measurement accuracy
6.Quick installation and maintenance
Modular design simplifies on-site installation steps and later maintenance processes, improving efficiency
7.Historical data storage function
Automatically records gas usage history for the past 6-12 months, convenient for traceability and query
8.Overflow protection function
Built-in overflow detection module, which automatically cuts off gas supply when flow exceeds the safe range, avoiding risks
