Products Description
Viewshine Indoor Gas Meter is designed for installation in straight through pipelines and narrow spaces, using a vertically installed ultrasonic design with a measurement range of 0.016-6m ³/h. Its sensitive ultrasonic core and temperature compensation provide excellent accuracy and stability under all flow conditions, while pulse/data output can be seamlessly controlled through a GPRS valve controller for remote data collection and closure. It has a compact structure, is easy to install, and supports key functions including data storage security, automatic fault detection with alarms, and low-voltage absorption. This powerful solution is highly suitable for enclosed instrument boxes, ensuring reliable, long-distance gas management with uncompromising accuracy.

Advantages
1. Vertical/horizontal design for spatial optimization
The compact external dimensions are designed specifically for enclosed pipelines and cluster instrument boxes, making it easy to install in narrow spaces without affecting performance.
2. Zero mechanical wear ultrasonic technology
Advanced non-contact measurement eliminates moving parts, ensuring an accuracy of ± 0.5% and continuous drift free operation for over 10 years.
3.0.016-6m ³/h dynamic range, with micro flow sensitivity
By accurately capturing natural gas consumption from minimum flow to peak flow through high-resolution ultrasonic sensors, it can adapt to fluctuations in residential and commercial demand.
4.20 ℃ standardized temperature compensation
Real time algorithm adjustment offsets thermal changes, ensuring accuracy in accordance with EN14236 under all environmental conditions.
5. Proactive safety ecosystem
Integrated LCD fault alarm+encrypted data storage+remote valve control with GPRS support, providing end-to-end protection against tampering, leakage, and data breaches.
