BL-CH4 Drone Methane Detector

For gas detection like oil and gas pipeline inspection, refinery inspection, industrial park, landfill, BLV Tech is committed to meet the complex operation needs of customers and providing unparalleled efficiency and accuracy. Now BLV tech has launched a flagship drone payload, BL-CH4, a lightweight drone-based laser methane detection sensor. BL-CH4 adopts an integrated design, which integrates five modules: laser receiver, laser indicator light, laser emission, RGB camera and laser ranging. Its advanced sensor arrays, combined with sophisticated algorithms, quickly identify methane sources, helping to quickly spot leaks and take emergency response measures.

In gas inspection, For large area detection, BL-CH4 adopts unique automatic rotation detection. The rotation angle of different angles can be selected to cover the monitoring different sizes of area. It can realize automatic, all-round and efficient inspection.
