Urban Gas Networks

Enables fast and safe methane leak detection across complex urban pipeline systems, including densely populated areas. UAV-based inspections reduce the need for manual access, improve response times, and enhance public safety while supporting efficient network maintenance.

Purway’s UAV-based methane detection system combines TDLAS (Tunable Diode Laser Absorption Spectroscopy) laser sensing with real-time video to identify leaks quickly and accurately from the air. As the drone follows a planned route, the sensor scans for methane while live data and visuals are transmitted to the operator for immediate awareness and post-flight analysis. For detailed step-by-step guide, see here.
