UAV Methane Detection — Latest Advances and the Current State of the Markets
A methane plume with an estimated volume equivalent to roughly 1% of total U.S. natural gas system daily emissions in 2018 was released from a yet to be confirmed source in Florida, USA on May 2, 2020.
LASER SYSTEM FOR DETECTING METHANE LEAKS ALONG TRANSPORT PIPELINES AND STORAGE AREAS
ALMA G5 is based on the utilization of laser absorption spectrophotometer of methane gas for gas mesurement. The system detects natural gas leaks by emitting a laser at a particular wavelength and analyzing the light reflection from an object to determine how much was absorbed by the methane in the natural gas. The measured gas volume is expressed by methane column density (ppm × m): methane density (ppm) multiplied by length (m).
ALMA G5 features
Airborne device mounted on helicopters and fixed wing aircrafts;
Full automation;
Detects faster than conventional method (detection speed: 0.1 sec);
Methane-only sensitivity. No false alarm;
User-friendly software;
Automatic and continuously performs self-check to ensure ability to detect gas;
Pilot camera and monitor to aim laser;
Each leak detection is reported with time, gas concentration, GPS coordinates and 4K image.

Maximum flexibility to install on any type of UAV
LMF G2
REQUEST A QUOTE
Remote Laser Methane Detector for professional UAVs. The most notable advantage of this new generation LMF G2 is its two-axis gyro stabilization system, which greatly enhances the sensor's stability and maneuverability. LMF may be applied for remote monitoring of natural gas pipelines including other gas facilities where leaks may be suspected.
Features and Benefits
Full automation
Detects faster than conventional method (detection speed: 0.1sec)
Methane-only sensitivity; no false reports
User-friendly software
Archives data for the entire period of operation
Automatic calibration and self-check during the operation
The Optical Unit (OU) of the LMF G2 detector is installed on a gyro stabilized platform so that the laser beam is continuously directed towards pipelines and other natural gas facilities.

FAQ
Honest answers to important questions
No, each device is designed to detect a specific gas. This provides a 100% probability of leak detection of methane and not any other gas.
Laser radiation is completely safe, it corresponds to class 1.
Yes. It is an active device, it emits at a certain narrow wavelength, so it does not need additional signal sources.
No. The detector contains a reference container with methane inside and calibration is performed at each start-up and during operation.
The detector does not need to be verified because it is not a measuring tool.
It works remotely. There is no direct contact with the hazardous environment.
Yes, because glass transmits the near infrared radiation well.
Our company specializes in methane detectors, but at your request we can supply a fully ready-to-use complex. Due to our partnership with UAV manufacturers, we can fully integrate the detector into the UAV design.
