- 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
Application/s:
- Pipelines
- Fixed wing aircraft
- Underground gas storage
- Gas distribution stations
- Gas processing plant
- Gas storage
Overview:
ALMA G5 (Airborne Laser Methane Assessment) is based on the utilisation of laser absorption spectrophoto-meter of methane gas for gas measurement. The system detects natural gas leaks by emitting a laser at a particular wavelength and analysing 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 is a system of airborne surveying of natural gas pipelines and storage facilities. The detector operation principle is based on diode-laser spectroscopy, which provides high reliability, accuracy and selectivity.
The device is fully automated and can continuously work without an operator, while storing the results in computer memory. The detector includes a GPS system that determines the flight route coordinates and leak points. Upon leak detection, the operator receives a light and sound signal, and the monitor displays a photo and a Google map of the leak site.
The detectors are designed for operation in temperate and cold climates; they comprise an optical unit and an electronics case.
