PN 903-8797, Rev A
Application
The 241CE II Analyzer is intended for applications that require hydrocarbon
dewpoint (HCDP) temperature measurements of natural gas. The analyzer
can also be congured to accept an optional, external water signal to provide
external water dewpoint (WDP) or external water content (WCT) measure-
ment outputs. The measurements for the HCDP and the external WDP/WCT are
displayed on the User Interface. The external signal does not aect the internal
operations of the analyzer, nor does it trigger alarms from the analyzer.
The 241CE II Analyzer is able to measure, internally, a water dewpoint tempera-
ture, but this measurement is used primarily for compensation in the calcula-
tion of HCDP measurements (to dierentiate between hydrocarbon and water
condensate); therefore, it is intended for diagnostic purposes only.
IMPORTANT
If your application requires WDP and WCT measurements, these
output signals must originate from an external source, such as the
AMETEK 3050-OLV Moisture Analyzer.
During normal operation, the analyzer continuously executes the measuring
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 2.
