DJI U10 Laser methane gas detector Price

laser methane gas detector for DJI M350

I. Technical Principle

The drone-based laser methane detector primarily operates on the principle of laser absorption spectroscopy. The basic principle involves a laser beam passing through the atmosphere and being scattered back after traveling a certain distance. By receiving the scattered light and measuring changes in irradiance, the concentration of methane is calculated. The device typically emits two laser beams: one red or green laser for targeting the detection area and another infrared laser for measuring methane gas at a distance.

II. Advantages and Features

  • Non-Contact Detection: Avoids potential safety hazards associated with traditional detection methods and reduces direct contact between personnel and potentially hazardous areas.
  • High Sensitivity and Fast Response: Accurately detects trace amounts of methane leaks and responds quickly, enhancing detection accuracy and timeliness.
  • Long-Distance Measurement: Capable of detecting over distances of several hundred meters or more, suitable for various complex environments and hard-to-reach areas.
  • Real-Time Data Transmission and Monitoring: Enables real-time monitoring and early warning of gas leaks through real-time data transmission and remote monitoring systems, enhancing safety measures.
  • Reduced Labor Costs: Decreases reliance on manual inspections, reduces labor costs, and improves inspection efficiency.

III. Application Scenarios

The drone-based laser methane detector is widely used in the following fields:

  • Urban Gas Distribution Pipelines: Detects leaks in gas pipelines to ensure the safety of urban gas supply.
  • Petroleum and Petrochemical Industries: Detects methane gas concentrations in refineries, chemical plants, etc., to prevent explosions and other accidents.
  • Metallurgical and Power Industries: Detects gas leaks in locations where leaks may occur, ensuring production safety.
  • Environmental Monitoring: Monitors methane concentrations in the atmosphere to assess environmental quality and pollution levels.
  • Other Complex Environments: Inspects pipelines in landfill sites, complex terrain areas, etc.

IV. Use Case

Take the CH-4 drone methane telemetry instrument as an example. This device features high sensitivity, fast detection response, and cost reduction. It can detect minute leaks from a height of 80 meters and complete gas leak detection at the target point within just 5 milliseconds. During inspections, the drone does not need to pause, displaying the methane concentration of the current area in real-time and automatically triggering audible and visual alarms and recording data (time, coordinates, leak concentration, site photos) upon detecting a leak. This information is used to automatically generate inspection reports later.

V. Conclusion

As an advanced gas detection device, the drone-based laser methane detector plays a significant role in ensuring public safety, improving inspection efficiency, and reducing labor costs. With ongoing technological advancements and expanding application scenarios, its prospects will continue to broaden.
