Installing The Sample Probe - Ametek 241CE II User Manual

The sample gas pressure must be less than the maximum working pressure
(MWP) rating of each sample system component. The MWP of the 241CE II An-
alyzer 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 particles, liquid droplets, or waxes. Since
liquids can occasionally appear in the process stream and in the Sample Line,
AMETEK recommends mounting 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 entrain-
ment, the length of the Sample Probe must be between one-third and one-
half the pipeline diameter, and the probe must contain an isolation valve.

See the probe manufacturer's installation instructions and drawings
for installation information.
If your Sample Probe is supplied by AMETEK, see Appendix B.
All regulatory agency and company safety procedures and installa-
tion procedures must be followed during installation of the Sample
Probe. 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 at-
tempting to install the Sample Probe assembly without the use of a
breathing apparatus.
