Principle of measurement (ppm-m)

Laser Methane is based on method of Tunable Diode Laser Absorption Spectroscopy (TDLAS) for gas measurement. The system detects methane gas leaks by emitting a Laser at particular wavelengths and analyzing the light reflected back from the ground to determine how much was absorbed by the methane in the natural gas. The measured gas volume is expressed by the methane column density (ppm-m): methane density(ppm) multiplied by thickness (m).
