Aurora TDLAS Hygrometer

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.”

GE’s experience in moisture measurement includes aluminum oxide, polymer capacitance and chilled mirror sensors. GE’s heritage also includes the development of the first injection diode laser in 1962 by Dr. Robert Hall in Schenectady, NY. The compact and inexpensive diode laser made it possible for compact discs, laser printers and fiber optic telecommunications. The new Aurora TDLAS hygrometer enables natural gas processing and transportation facilities to monitor moisture content in real time with high precision and reliability.
