This is a device for noncontact measurement of natural gas CH4 concentration based on laser absorption spectroscopy

When the instrument is working it emits a specific wavelength range the center wavelength is not the same for different gases under testof the detection laser which is diffusely reflected when it ments reflector eg the ground valves pipelines walls etc and part of the laser is returned to the detection unit of the instrument In the beam path if there is a gas leakage of the measured gas to form a gas cloud the gas cloud will be absorbed by the detection laser the amount unabsorbed light and the ratio of the amount of absorbed light and the concentration of the gas cloud into a function of proportionality through the calculation of the ratio of the inverse of the concentration of the gas cloud
