A20 Vehicle-Based Laser Methane Detection System
The A20 is an advanced vehicle-mounted gas leak inspection system designed to support efficient surveys of natural gas distribution networks and other gas-related infrastructure. By combining laser-based methane sensing, high-precision positioning, and intelligent inspection software, it helps operators identify potential leak locations while collecting geographically referenced field data.
Designed for mobile inspection workflows, the A20 enables survey teams to cover extensive pipeline networks without relying solely on conventional point-by-point inspection methods. Its integrated mapping and data management capabilities provide a clearer overview of inspection routes, detected gas concentrations, and potential anomalies.
Real-Time Mapping and Intelligent Data Visualization
The A20 displays inspection results on a geographic information map, allowing operators to review vehicle routes, methane readings, anomaly alerts, and associated imaging data in one interface. This consolidated view helps inspection teams understand where potential gas leak indications occur and prioritize areas for further investigation.
By linking detection results with location information, the system supports structured inspection records, easier route-based analysis, and more informed maintenance planning.
AI-Assisted Anomaly Filtering
The A20 incorporates an AI-based filtering algorithm to help distinguish potential leak indications from background interference and reduce unnecessary false alarms. By combining gas measurements with environmental and location-related information, the system supports more efficient evaluation of inspection results.
Historical inspection data can also be reviewed to assess recurring anomalies, compare survey findings, and help identify locations that may require follow-up testing.
Continuous Inspection Without Routine Stops
Designed for vehicle-based surveys, the A20 supports in-motion gas leak screening along accessible pipeline routes. This approach helps inspection teams collect data across large service areas while reducing the need to stop repeatedly for individual measurements.
Automatic route planning helps organize inspection coverage and improve the efficiency of distribution network surveys. The resulting location-linked records provide a practical foundation for reviewing completed routes and planning subsequent inspections.
Integrated Sensing and Positioning Technology
The system combines a methane/ethane analyzer, a high-precision positioning module, and dedicated leak detection software. Panoramic imaging and multi-parameter environmental data can complement gas measurements, helping operators interpret suspected anomalies in the context of the surrounding inspection environment.
Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), the A20 detects methane based on its characteristic optical absorption. Its selective laser measurement approach is designed to support methane monitoring in real-world roadside environments where vehicle exhaust and other background sources may complicate leak identification.
Applications Across Gas Infrastructure
Natural Gas Distribution Networks
Conduct mobile surveys along underground gas pipeline corridors to screen for potential surface emissions associated with pipeline leaks.
Refineries and Petrochemical Facilities
Support gas leak screening around processing facilities, storage areas, and other industrial infrastructure where vehicle access is suitable.
Landfill Gas Monitoring
Survey accessible areas around landfills and methane-producing sites to help identify locations requiring further emissions assessment.
Underground Storage Tank Areas
Support inspection surveys around suitable underground storage tank installations and associated infrastructure to investigate potential gas emissions.
Pipeline Maintenance and Risk Assessment
Maintain route-based inspection records, compare historical findings, and help prioritize potential anomalies for follow-up investigation and maintenance.
Smarter Mobile Inspection for Gas Leak Management
The A20 combines mobile laser sensing, intelligent mapping, and software-based data analysis to support more systematic gas leak inspections. By connecting detection results with geographic locations and inspection history, it helps utility operators improve survey coverage, streamline field reporting, and make better-informed decisions about pipeline maintenance and risk management.
