A20 Roof-Mounted Laser Methane Detection System

The A20 is a roof-mounted laser methane detection system developed for mobile inspection of natural gas distribution networks and underground pipeline infrastructure. Installed on a survey vehicle, the system combines laser gas sensing, positioning technology, and dedicated inspection software to help operators identify potential methane leak locations while covering extensive pipeline routes.

Its vehicle-roof configuration supports systematic gas surveys across accessible roads and pipeline corridors, providing an efficient alternative to inspection methods that rely entirely on stationary measurements or manual field checks.

Continuous Mobile Inspection Along Pipeline Routes

Designed for on-road operation, the A20 collects gas detection information as the vehicle travels through designated survey areas. This approach helps inspection teams cover larger service territories and identify locations that may require closer examination, without stopping for every individual measurement.

The system supports mobile screening of underground natural gas distribution networks, helping utilities organize field inspections and prioritize follow-up investigations based on recorded findings.

Real-Time Mapping and Geographic Leak Identification

The A20 integrates gas measurements with positioning data to display inspection routes, detected concentrations, anomaly alerts, and associated imaging on a geographic information map. Operators can review survey conditions through a centralized interface and identify where potential leak indications occur along the inspected route.

By linking detection results to geographic locations, the system helps create traceable inspection records, simplifies field reporting, and supports more efficient maintenance planning.

AI-Assisted Anomaly Screening

The A20 incorporates AI-assisted false alarm filtering to help distinguish potential leak signals from background interference. Combined with environmental information and location-related data, this function supports more consistent interpretation of field measurements and helps inspection teams focus on areas that warrant further assessment.

Recorded inspection history can also be used to compare findings across surveys, identify recurring anomalies, and support pipeline risk evaluation.

Laser-Based Methane Sensing Technology

Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), the A20 detects methane through its characteristic optical absorption properties. The selective laser sensing method is designed to support methane monitoring in roadside environments where vehicle exhaust and other background gases may complicate conventional gas detection.

The integrated methane/ethane analyzer provides additional gas composition information to assist with leak investigation. Detection results should be evaluated alongside site conditions and, where necessary, confirmed through appropriate follow-up testing.

Integrated Positioning, Imaging, and Inspection Software

The A20 combines a gas analyzer, positioning module, and proprietary inspection software in one mobile survey solution. Panoramic imaging and environmental data integration help provide context for recorded gas indications, making it easier for operators to review potential anomalies and organize inspection findings.

Automatic route planning supports more structured survey coverage, while historical data management helps teams maintain inspection records and plan subsequent maintenance activities.

A More Efficient Approach to Mobile Gas Leak Surveys

The A20 brings roof-mounted laser sensing, geographic data visualization, and intelligent inspection software together in a coordinated mobile monitoring solution. By combining continuous route-based screening with location-linked records and AI-assisted analysis, it helps utility operators improve survey coverage, organize inspection findings, and make better-informed decisions about pipeline maintenance.
