Chapter 1. Features
and capabilities
1.1 Overview
Panametrics’ 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”.
