G20 Vehicle-Mounted Portable TDLAS Methane & Ethane Leak Detector

High-sensitivity laser detection for natural gas pipeline inspection and last-mile leak surveys.

The AiLF G20 combines portable operation with vehicle-mounted inspection, measuring methane and ethane at ppb-level resolution for rapid natural gas leak detection and gas composition analysis.

High-Sensitivity Methane and Ethane Detection

The G20 provides ppb-level resolution, with a resolution of 1 ppb for methane and 0.5 ppb for ethane. By measuring methane and ethane concentrations together, operators can analyze gas composition and use the measured gas proportion to help identify whether a suspected leak is associated with natural gas.

Portable and Vehicle-Mounted Inspection

The G20 is designed for both handheld inspection and vehicle-mounted deployment. When combined with the V-Dock, the detector can be installed on small, slow-moving vehicles such as electric bicycles. This enables efficient inspection of residential communities, courtyards, and other areas where conventional vehicle-based pipeline surveys may be difficult, helping extend gas leak inspection to the last mile of distribution networks.

Easy Docking and System Integration

The detector and docking station use a snap-fit connection, allowing the G20 to be quickly installed or removed according to the inspection task. The system supports Bluetooth communication and ADA software, enabling measurement data connection and inspection management.

Accurate Field Detection

The G20 combines laser-based gas measurement with an AI spatiotemporal false-alarm filtering algorithm, which is designed to reduce false alarms and improve the correlation between detected alarms and potential leak locations.

Typical Applications

The G20 is suitable for:

• Natural gas pipeline leak detection
• Last-mile gas distribution inspection
• Residential community and courtyard pipeline surveys
• Gas infrastructure inspection
• Industrial gas leak detection
• Environmental methane and ethane monitoring
