GE’s Aurora analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to measure moisture in natural gas rapidly and accurately. The analyzer is suitable for installation in hazardous areas and operates over a wide range of environmental conditions. Aurora’s fast response quickly alerts and documents when moisture concentrations are out of compliance. Once process upsets are corrected and the gas dries out, the fast response enables natural gas to be cleared for entry into the “energy grid.”
