Discover the Purway CH4 Laser Methane Leak Detector Model II, the latest innovation in UAV-mounted gas detection technology. This advanced detector is specifically designed for compatibility with the DJI Matrice 300 series and DJI Pilot 2 flight application, employing state-of-the-art TDLAS technology for unmatched precision in methane gas detection.

Key Features:

• Extended Detection Range: A remarkable 300-meter detection capability.
• Rapid Response: A swift 10ms reaction time for immediate detection.
• Detailed reporting of concentration and GPS identification of leak location.

Our device seamlessly merges a sophisticated detection laser and a visible light sensor, offering a dual advantage of precision and visual insight during methane inspections. The incorporation of intelligent gimbal stabilization technology further enhances accuracy, empowering users to swiftly identify and address potential safety hazards.

Purpose and Applications: Enhancing Gas Transmission SafetyEnsuring the integrity of gas transmission infrastructure is a paramount concern for operators. Traditional methods of monitoring pipeline tightness are often labor-intensive and time-consuming. Recognizing this challenge, Purway has innovated air-borne inspection methods, for well sites, tanks batteries and natural gas pipelines, enhancing compliance, efficiency and accuracy.Our primary objective is to revolutionize natural gas leak detection. We achieve this by equipping unmanned aerial vehicles (UAVs) with advanced remote-sensing methane detectors. This approach has been thoroughly researched and developed, with extensive studies focusing on both artificial and real-world methane leak simulations.

Key Insights from Our Research:

• Focused Experiments: Initial trials with artificial methane sources established baseline conditions for comprehensive field tests.
• Real-World Testing: Subsequent experiments on actual sections of natural gas pipelines provided valuable, actionable data.
• Data Analysis with AI: The collected measurement data, paired with spatial coordinates, were analyzed using sophisticated machine learning techniques. This analysis identified areas with elevated methane levels, demonstrating spatial correlations.
• Optimizing Flight Parameters: Research highlighted the impact of UAV flight altitude and speed on detection accuracy. The Purway UAV Laser Methane Leak Detector Model II showed optimal performance at lower altitudes (50 to 200 meters) and moderate speeds (5-9m/s).

These findings confirm the effectiveness of the Purway UAV Laser Methane Leak Detector Model II as a preliminary tool for identifying potential leaks in natural gas infrastructure. Its optimized use at specified altitudes and speeds ensures precise, reliable, and efficient leak detection, marking a significant advancement in safety and compliance protocols.  

Specific molecules will absorb specific wavelengths of light. The absorption of light by a homogeneous medium(air mass) is proportional to the thickness and concentration of the air mass. Use the beam to illuminate the target and analyze the characteristics of the returned light to obtain the concentration.
