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.

Pain Points For The Traditional Detection

· Difficult to detect low concentrations of methane leak in large

 or complex environments. · Time-consuming on manual operation and on-site sampling. · The covered area is limited for a handheld devices or fixed

 monitoring station. · Risk-taking to detect in a remote or hazardous areas.

Advantages of Drone Methane Technology By BL-CH4


· Based on drone technology, it can fly and detect all kinds of scenarios

 without limitation efficiently and accurately.

· TDLAS technology enables the system with high performance in
 sensitivity and quick response speed, also support the workin distance
 up to 300m.
· Diversification on software supports both APP / Cloud Platform for the
 flight monitoring and management.
