Pergam ALMA - Model G2 -Laser System for Detecting Methane Leaks

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).
