• Sample Gas Inlet Pressure: You must have a minimum pressure of 0.5 psig for gas to flow
through the Analyzer.
WARNING
The maximum allowable inlet pressure for safe operation is 150 psig. Sites, where gas
pressure exceeds 150 psig, require a pressure reducing regulator installed between the
pipeline tap and Analyzer.
CAUTION
When the sample gas is hot and wet, it could cause water to condense in the Sample Line
or Analyzer
• For best operation, we recommend installing an AMI Demister and Analyzer Guardian,
which can be purchased separately
— The vertically-mounted Demister is designed to quickly and effectively reduce sample
pipeline gas temperatures to ambient. The Demister rapidly cools warm, saturated gas,
causing the liquids to condense out and drain back into the pipeline without requiring
maintenance of other solutions, such as drip pots and coalescing filters
— The Analyzer Guardian mounts directly on top of the Demister.
It uses a combination of a
hydrophobic/oleophobic membrane and perforated flexible stainless-steel disc that work in
tandem, creating a barrier against saturated/wet gas, liquid slugs and particulates commonly found
in pipeline gas.
— The Analyzer Guardian is designed to automatically shut-off gas flow to the gas analyzer when a
liquid slug occurs. Once the liquid slug passes, gas flow will resume.
• All gas connections will require using the supplied ferrule set, ¼" stainless steel compression
fittings and tubing
