A20 Vehicle-Based PPB Laser Gas Detection System

Advanced Mobile Detection for Natural Gas Networks

The A20 is a vehicle-mounted laser gas detection system developed for efficient natural gas pipeline surveys. Integrating a mid-infrared spectrometer, high-precision positioning, AI imaging, and an intelligent control system, it brings multiple detection and analysis functions together in one mobile inspection platform.

Operating along roads above buried natural gas pipelines, the A20 performs continuous mobile surveys without requiring the inspection vehicle to stop at every potential leak location. Its high-frequency sampling capability captures changes in ambient methane and ethane concentrations, helping inspection teams identify potential gas leakage signals across extensive pipeline networks.

High-Sensitivity Detection with Mid-Infrared Laser Technology

At the core of the A20 is AiLF's mid-infrared laser absorption spectroscopy technology, designed for high-sensitivity methane and ethane measurement. By monitoring changes in both gas concentrations, the system provides additional information for identifying potential natural gas leakage in outdoor environments.

Its low detection limit supports the identification of weak gas signals, while the system architecture is designed to balance sensitive measurement with the maintainability required for industrial field applications.

Continuous Mobile Sampling Along Pipeline Routes

The A20 is designed to conduct gas surveys while the vehicle is moving. Its rapid sampling capability allows the system to collect frequent gas measurements along designated inspection routes, reducing the need for stationary testing and improving patrol efficiency.

This mobile inspection approach is particularly useful for municipal gas networks, where extensive underground pipeline infrastructure requires regular and systematic monitoring.

AI Imaging and Intelligent Signal Processing

To improve the reliability of field detection, the A20 incorporates AI-based false alarm filtering to help distinguish suspicious gas signals from background interference.

AI imaging, panoramic visual information, and multi-parameter environmental sensing provide additional context for analyzing potential anomalies. These integrated data sources also create a foundation for intelligent algorithms and further inspection analysis.

Precise Positioning and Risk-Based Inspection

High-precision positioning navigation associates gas measurements with their corresponding geographic locations. Combined with automatic route planning, the system helps inspection teams organize patrol coverage and identify areas that may require closer examination.

Continuous inspection histories allow operators to compare findings across different patrols, track recurring anomalies, and evaluate potential leakage risks. This supports more informed maintenance planning and follow-up inspection decisions.

Designed for Reliable Industrial Operation

The A20 combines laboratory-oriented detection performance with practical industrial design. Its temperature control system, wide operating temperature adaptability, and low filtration requirements help maintain stable operation while simplifying routine maintenance.

The integrated mobile platform is intended to support long-term pipeline inspection under varying outdoor and industrial conditions.
