A20 Vehicle-Based TDLAS Methane Leak Detection System for Pipeline Inspection

Vehicle Based TDLAS Laser Methane Leakage Detector System Natural Gas Pipeline Networks inspection

Product Introduction

The AiLF A20 is a vehicle-based natural gas leak inspection system designed for efficient methane detection across gas distribution networks. Based on TDLAS (Tunable Diode Laser Absorption Spectroscopy), the system detects methane while continuously recording the inspection route, gas concentration, anomaly alerts, and other field data.

The A20 combines a methane/ethane analyzer, high-precision positioning module, panoramic imaging, environmental sensing, and proprietary leak detection software. Its real-time geographic information map displays the vehicle location and detected gas concentration, helping operators quickly identify and review potential leakage areas.

Mobile Inspection with Real-Time Mapping

The A20 enables continuous vehicle-based inspection without stopping, while detection data and route information are recorded throughout the survey. Users can view gas concentration, inspection paths, and anomaly information on a real-time digital map, providing a clear overview of the inspected area.

TDLAS Methane Detection

The A20 uses TDLAS technology for methane detection at the characteristic wavelength of 1.65 μm. The laser-based measurement method is designed for methane-specific detection with no relevant cross-sensitivity to common atmospheric gases such as vehicle exhaust gases, according to the supplied product information.

AI-Assisted Leak Detection

An AI-based false-alarm filtering algorithm helps reduce false alarms and improve the identification of abnormal gas signals. Continuous historical data also allows operators to review inspection results and evaluate potential leakage risks over time.

High-Precision Positioning and Multi-Parameter Sensing

The A20 integrates high-precision positioning, panoramic imaging, and environmental information with gas detection data. This provides a more complete set of inspection data and supports the development and application of intelligent AI-based analysis.

Automated Route Planning

The system supports automatic route planning to improve the efficiency of gas distribution network inspections and help operators organize large-scale vehicle-based surveys.

Typical Applications

The A20 is designed for natural gas distribution network inspection, urban gas infrastructure surveys, methane leak detection, and continuous pipeline inspection.
