Application

1-2 | Model 241CE II Hydrocarbon Dewpoint Analyzer
The Model 241CE II Analyzer is intended for applications that require hy-
drocarbon dewpoint (HCDP) temperature measurements of natural gas.
The analyzer can also be configured to accept an optional, external water
signal to provide external water dewpoint (WDP) or external water con-
tent (WCT) measurement outputs. The measurements for the HCDP and
the external WDP/WCT are displayed on the User Interface. The external
signal does not affect the internal operations of the analyzer, nor does it
trigger alarms from the analyzer.
The Model 241CE II Analyzer is able to measure, internally, a water dew-
point temperature, but this measurement is used primarily for compensa-
tion in the calculation of HCDP measurements (to differentiate between
hydrocarbon and water condensate); therefore, it is intended for diag-
nostic purposes only.

IMPORTANT
If your application requires WDP and WCT measurements, these
NOTE
output signals must originate from an external source, such as the
AMETEK Model 3050-OLV Moisture Analyzer.
During normal operation, the analyzer continuously executes the measur-
ing cycle which consists of three stages performed in the following order:
• Purging/Hold Stage
• Cooling Stage
• Warming Stage
For details about each measuring cycle stage see "About the Measuring
Cycle" in Chapter 3.
