G20 Vehicle-Mounted PPB-Level Methane Ethane Leak Detector

G20 Vehicle-Mounted PPB-Level Methane Ethane Leak Detector

Product Overview

The AiLF Instruments G20 is a portable laser gas detector designed for vehicle-assisted natural gas leak inspections and high-sensitivity gas analysis. Using advanced mid-infrared laser absorption spectroscopy technology, the G20 measures methane, ethane, and water vapor in sampled air to help identify potential natural gas leaks.

With reported ethane detection capability as low as 0.5 ppb, the G20 supports sensitive field measurements and helps operators distinguish natural gas leakage from other methane sources by analyzing methane and ethane concentrations together.

When equipped with the compatible V-Dock, the G20 can be mounted on small, slow-moving vehicles such as electric bicycles. This configuration complements the AiLF A20 system and supports last-mile pipeline surveys in residential communities, courtyards, and local gas distribution networks.

Key Features and Benefits

1. PPB-Level Ethane Detection

The G20 is designed to detect trace ethane concentrations, with a reported detection capability as low as 0.5 ppb. High sensitivity helps identify potential natural gas leaks and supports investigation of low-concentration gas emissions.

2. Methane and Ethane Differentiation

The detector measures methane and ethane concentrations to help determine whether a methane indication may originate from natural gas. Analyzing the relative proportions of these gases provides useful information for distinguishing potential pipeline leaks from other methane sources.

3. Advanced Laser Absorption Spectroscopy

The G20 uses advanced mid-infrared laser absorption spectroscopy for sensitive gas analysis. Its laser-based detection technology supports rapid measurement of methane and ethane, helping improve field inspection efficiency.

4. Vehicle-Mounted and Portable Operation

With the compatible V-Dock, the G20 can be installed on small, slow-moving vehicles, including electric bicycles, for mobile pipeline surveys. The main unit and docking station feature snap-fastener connections for convenient assembly and removal, allowing operators to switch between vehicle-mounted and handheld inspection.

5. AI-Assisted False Alarm Filtering

The G20 incorporates an AI-based spatiotemporal model for false alarm filtering. By evaluating spatial and temporal patterns, the system is designed to reduce false alarms and improve the relationship between reported alerts and potential leak locations.

6. Rapid Field Measurement

The G20 provides methane and ethane concentration readings to support timely investigation of suspected leaks. Rapid field analysis helps operators identify areas requiring further inspection and improve the efficiency of routine pipeline surveys.

7. Integration with Natural Gas Inspection Systems

The G20 can complement the AiLF A20 system when deployed with compatible equipment. Its portable design and vehicle-mounting capability make it suitable for inspecting local distribution networks, residential areas, and other locations where flexible access is important.

Applications

Natural Gas Distribution Pipeline Inspection
