In the natural gas, oil refineries, and chemical plants industries, methane gas leak away is high-risk events, the pipeline inspection is an effective way to find leaks, especially by using a drone, drone-mounted a remote methane leak detector, the drone laser Methane gas leak detector can efficiency and high accuracy to do this work.
Natural gas is important life energy, and the safety of gas pipelines is very important. The gas pipeline has the characteristics of long-distance and wide distribution. It is mostly laid underground in cities, passing rivers, gullies, railways, and highways along the way. The terrain is complicated, which restricts the operation method of manual line inspection, and brings inconvenience to the regular inspection of pipelines. Security risks. Gas pipelines are usually linearly distributed, and their pipeline lengths often reach hundreds of kilometers. The patrol of gas pipelines is mainly to monitor the pipeline itself and the environmental conditions within one kilometer around the pipeline. Compared with the traditional manual inspections and vehicle inspections, use of drones in oil and gas industry can effectively solve these environmental constraints. The UAV is equipped with a high-precision laser methane telemeter to penetrate various complex environments to achieve manual accurate point-to-point detection, flight detection of gas pipeline routes, and scan detection of key areas.
The laser methane gas detector based on semiconductor laser absorption spectroscopy (TDLAS) technology. It can detect methane gas concentration and other parameters in various environments with high accuracy, fast response, high reliability, and low operating costs,
We have released the gas Methane gas leak detector for DJI Matrice 300 drone, you can check the DJI M300 drone Laser Methane gas leak detector

The Typical application of drone gas leak detection
1:Natural gas pipeline inspection
During the inspection process, the inspection status (including drone status, telemeter status, methane measurement results) can be viewed in real-time. In case of pipeline leakage, terminal equipment will automatically sound and light alarm and record data (time, coordinates, leakage concentration, on-site photos) In order to automatically generate inspection reports later
2:Natural gas station inspection
Frame selection of the station area and automatic production of inspection routes. The program can also be used in landfills, On-site methane leakage monitoring, methane leakage detection before LNG carriers enter the port. After the inspection is completed, the leak point is automatically marked, and the user can click the icon to view detailed information).
3:Residential building gas leak detection
Perform manual flight and automatic flight detection for residential buildings. The CH-4 UAV laser methane telemeter can complete the detection of natural gas leakage at the target point in only 0.1S. The UAV does not need to stop during the inspection process and displays the current concentration of natural gas in the kitchen of the household in real-time.
