Abstract
The amount of water vapor in natural gas at different levels, including at levels below 10 ppmv, is measured by directing a light from a quantum cascade laser at a frequency in the 5.01 to 5.03 micron or the 5.07 to 50.9 micron wavelength range through natural gas containing water vapor. A detector is configured to detect the intensity of light transmitted through the natural gas from the laser; and an analyzer is coupled to the detector for determining the level of water vapor in the natural gas.
