2.8.4.1
Gas velocity class ranges
The gas velocity class ranges are optimized to cover the defined operation range of the
meter. The lower limit of the gas velocity range classes is defined by the parameter "Min.
VOG for warnings". The upper limit is defined by "VOG limit". Both parameters are config-
ured in the User Warnings window (see "Configuration" tab
).
2.8.4.2
Diagnostics Comparison Report
From the data collected in the Diagnostics Comparison Log, the Diagnostics Comparison
Report can be created using MEPAFLOW600 CBM (
). It provides an overview
of the velocity-dependent diagnostics and thus an easy health check. It contains:
– Basic meter data and meter operating data identifying the meter.
– Diagnostic Data Base provides information on the velocity range classes, the time
when the reference classes where filled (the current classes will always be showing
recent data), the Avg VOG in these classes and the standard deviation.
– Performance Change and Status give an easy, color-coded overview of Performance
and Status recorded in the reference classes and the current classes.
– The Diagnostics section shows graphs documenting the changes on Flow Profile,
Symmetry, Speed of Sound, Average Turbulence, Average SNR and Average AGC and
the configured Diagnostics Comparison Limits (see below).
2.8.4.3
Diagnostics Comparison Limits
The Diagnostics Comparison limits can be activated in order to generate a warning when
the difference between the diagnostic values in the reference classes and those in the cur-
rent classes surpass the Diagnostics Comparison limit values. These limits can be acti-
vated and configured in the User Warnings window (
