Installing The Sample Probe - Ametek 241CE II Operator's Manual

The sample gas pressure must be less than the maximum working pres-
sure (MWP) rating of each sample system component. The MWP of the
Model 241CE II Analyzer is 13 790 KPA (2000 PSI). Although the analyzer
is supplied with a filter to remove particulate and liquid aerosols, the
sample gas should not contain more than trace quantities of solid parti-
cles, liquid droplets, or waxes. Since liquids can occasionally appear in the
process stream and in the Sample Line, AMETEK recommends mount-
ing the analyzer higher than the process pipe to allow any liquids in the
Sample Line to drain back into the process pipe.

Installing the Sample Probe

A Sample Probe for this system is typically supplied by the customer. To
obtain a representative gas sample and to minimize problems with liquid
entrainment, the length of the Sample Probe must be between one-third
and one-half the pipeline diameter, and the probe must contain an isola-
tion valve.

See the probe manufacturer's installation instructions and drawings
for installation information.
NOTE
If your Sample Probe is supplied by AMETEK, see the Final "As-
Built" drawings in the analyzer Documentation Package.
!
All regulatory agency and company safety procedures and installation
procedures must be followed during installation of the Sample Probe.
WARNING
A breathing apparatus must be worn when installing the Sample
Probe. The process duct may be under positive pressure and injury
or death from toxic gases in the process could result from attempting
to install the Sample Probe assembly without the use of a breathing
apparatus.
