Natural gas pipeline surveys, tank inspections, landfill emission monitoring, gas well testing, plant safety audits — there are many applications of Laser Methane Copter. It’s second generation, LMC G2, is the latest creation of PERGAM, a manufacturer, distributor and service provider of world leading gas leak detection systems and SPH Engineering, world’s premier provider of mission planning software UgCS and drone integration services.

Compared to stationary gas leak detectors, drones are not only a more cost-efficient way to deal with the problem, but a much more effective one. With instant data transfer from UgCS data logger to pilots RC gas leaks can be detected instantly and more accurately. 

Key features

High sensor's sensitivity 1...50.000 ppm×m
Sensitive up to 30m distance from methane leak
Flight time up to 25 minutes
UgCS onboard data logger transfers data instantly to the remote control of the drone pilot and to UgCS desktop software
Data transmission enabled withing 5km distance
Laser detector is sensitive only to methane, so no false readings of other gases are possible
The system is easy to transport and operate, allowing companies to cover vast areas

UgCS software allows flying the drone on a constant height even over rough and mountainous areas, as its 3D maps and terrain following mode will cope with any kind of landscape. Adding a laser altimeter to the system will enable to fly in True Terrain Following mode.

The Integrated System

Laser Methane Detector

Laser Methane Detector by PERGAM is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.

The concept is based on Infrared Absorption Spectroscopy. Laser light in the spectral range of 1,65 μm is emitted. The laser light is reflected in the background and captured back in the instrument. The outgoing and incoming signals are compared with a built-in reference cell. If methane gas is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.

UgCS Data Logger

UgCS Data Logger is the key element that enables the full integration of the drone, laser methane detector, and ground control software UgCS. The onboard UgCS Data Logger, designed by SPH Engineering, saves the gas detector’s data in .txt format and transfers them instantly to the remote control of the drone pilot and to the desktop software UgCS. This allows operators to detect leaks in real time and ensure faster response time.

The UgCS Data Logger enables also to add a laser altimeter to enable the flight in True Terrain Following mode, which enables the drone (UAV) to accurately follow the terrain during the flight, based on data received from the laser altimeter. True Terrain Following enables the drone to fly at constant AGL altitude without a need to import precise Digital Elevation Model (DEM) height-map into UgCS.

The Drone

Currently, the UgCS Data Logger is compatible with DJI M600 and M600 Pro. It is a durable system which offers extended flight time (up to 25 minutes) and a 5-kilometre-long range of data transmission.

UgCS

Smooth operation is ensured by UgCS software, developed by SPH Engineering in Riga, Latvia. Besides supporting most industrial drones on the market, it offers several productivity-enhancing innovations: automatic Photogrammetry, Facade scan, and Search pattern tools. Most importantly for methane detection, UgCS software allows for the drone to be flown at a constant height, even over rough and mountainous areas, as its 3D maps and terrain-following mode can cope with any kind of landscape. UgCS's drone mission planning software also provides tools for the easy creation and calculation of flight paths, and for the interpretation of acquired data in a user-friendly manner.

One of the main components of the integrated system, enabling efficient survey planning is UgCS - flight planning software providing tools for easy creation and calculation of flight paths, and interpretation of acquired data in a user-friendly manner.
