The DiNelly eXoGyro System will reduce your operating costs of the aircraft to a minimum.


The ALMA (Airborne Laser Methane Assessment) is the solution for effective and economic pipeline and storage network monitorin ans inspection The ALMA is a cutting-edge laser based natural gas detection system that performs inspections at ground level while airborne.












The DiNelly eXoGyro System is engineered for the ALMA G2 sensor, supported by PERGAM-SUISSE AG switzerland.


To fly over pipelines with helicopters has proven itself as a monitoring measure to detect leaks or external influence.


The ALMA system is the solution to remote inspection of natural gas pipeline and storage networks:


  • The advantages of ALMA are numerous:
  • Airorne device mounted on a helicopter
  • Highly sensitive, wide measurement range
  • Real time measurement and alarm feature
  • Intensitive to other gases (water, vapor, propane)
  • Minimal interference with environment
  • Pilot camera and monitor to aim Laser
  • Digital video recording with up to 4 cameras to document laser position and area araound pipeline
  • Extensive data storage capacity
  • GPS tracking utilising map system navigation
  • Laser Range Finder
  • Post processing software
  • Optional IR camera installation






  • The principle of ALMA is based on a pulsed beam from a diode laser, which is pointed at the location to be inspected
  • The laser wavelenght of 1,65µm corresponds to the first absorption band of methane.
  • The laser beam aimed downwind of the pipeline, is reflected and the scattered reflection is collected by a receiving mirror.
  • A photo-detector receives the signal which is compared to the signal from a reference channel. (A laser beam through a curette with a stndardized methane sample.)
  • When methane is present the laser light will be absobed, and the deformation of the signal is proportional to the concentration of methane along the laser beam path.


The eXoGyro System safe your money due to reducing the operation cost of your aircraft as sensor platform.


One of the most important arguments for using the DiNelly mission platforms is that DiNelly uses gyrocopter technology and makes it unique worldwide as a Pioneer for professional applications,


The Gyrocopter autorotation technology stands for unique flight characteristics in turbulent and stormy weather conditions. As a result, this technology in the DiNelly eXoGyro system provides you with the highest degree of efficiency to work and fulfill your flight orders.
