REAL PROFILE:
On GENERAL FLOW error “1-4 channels down” the REAL profile is used to correct the channels with
errors. The real profile is sampled at a certain flow rate.
•
The REAL-profile correction has a limited validity.
When the actual profile changes too much, the previously sampled REAL-profile might not be
reliable anymore. The check for profile changes is done through flow-rate difference.
•
When the sampled REAL-profile flow rate differs too much from the actual flow-rate during REAL-
profile correction this is shown as a warning.
CORRECTION WARNINGS shows:
•
If there is too much flow variation for corrections, the corrections go on hold. When the corrections
are on hold the real time profile is used as a standard for correcting the flow.
•
If there are too much flow variations or channels failing, the sampling of the REAL profile goes on
hold. On release the sampling is started at maximum time for sampling a profile.
SYSTEM ERRORS shows:
The status of the system is divided into:
•
System Runtime Warnings. These are caused by system failures. These failures will not influence
the flow measurement.
•
System Runtime Alarms. These are caused by system failures. These failures might influence the
flow measurement.
Identified System Runtime Errors are numbered 1 to 60 are:
4.2.1 SYSTEM ERRORS
