A20 Vehicle-Based TDLAS Methane Leak Detection System for Gas Networks

A20 Vehicle-Based Methane Leak Detection System

The A20 is a mobile gas leak inspection system designed to help utilities and pipeline operators survey natural gas distribution networks more efficiently. Combining laser-based methane sensing, precision positioning, panoramic imaging, and dedicated inspection software, it provides a comprehensive view of potential gas leak anomalies along inspection routes.

Real-Time Mapping and Leak Visualization

The A20 displays inspection routes, methane concentration readings, anomaly alerts, and imaging information on a geographic map. By linking detection results to location data, the system helps operators identify suspicious areas, review inspection records, and prioritize follow-up investigations.

TDLAS Technology for Selective Methane Detection

Based on Tunable Diode Laser Absorption Spectroscopy (TDLAS), the A20 detects methane using its characteristic absorption wavelength. This selective measurement approach helps reduce interference from common atmospheric gases and vehicle exhaust, supporting more reliable methane leak screening in roadside environments.

AI-Assisted Anomaly Analysis

An AI-based filtering algorithm helps distinguish potential leak signals from background interference, supporting more effective anomaly assessment and reducing unnecessary false alarms. Historical inspection data can also be reviewed to evaluate potential leakage risks and support maintenance planning.

Smarter Routes, More Efficient Inspections

Designed for mobile pipeline patrols, the A20 supports route planning and continuous data collection during vehicle-based inspections. Operators can survey extensive pipeline networks without stopping at every inspection point, helping improve coverage and allocate field resources more effectively.

Applications

The A20 is suitable for urban natural gas distribution networks, gas pipeline corridors, industrial gas facilities, refineries, and other infrastructure requiring mobile methane leak surveys. Its integrated mapping and data analysis capabilities help inspection teams move toward more proactive, data-driven gas safety management.
