1.1 Overview
BH’s Aurora H2O
Moisture Analyzer for Natural Gas
makes it possible for natural gas processing and transportation
facilities to monitor moisture content in real-time with high precision and reliability.
The
Aurora H2O analyzer uses tunable diode laser absorption spectroscopy (TDLAS) to measure moisture in natural
gas at the speed of light. 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 quickly enables
natural gas to be cleared for entry into the “energy grid”.
