This is useful if the process conditions differ significantly from the
conditions during the calibration process since both high pressure and
high temperature results in an increase in the tube cross-section and a
change in path lengths and angles.
Please Note:
k-factor GeomCorr. A is for the Axial Path
k-factor GeomCorr. B is for the Swirl Path
k-factor GeomCorr. C is for the Half Square Path (if applicable)
k-factor GeomCorr. D is for the Direct Path (if applicable)
k-factor GeomCorr. Dia is the correction factor for the inner
diameter for the meter body at operation conditions
k – factor Linearization - When a meter is corrected after
calibration through linearization, the adjust factor will be flow
depending (interpolated between the calibration points). The meter
can have a linearization for each flow direction. This factor shows
the adjust factor calculated for the current operating flow (and
direction).
k – factor Adjustment - This is the factor when a meter is
corrected after calibration with one single adjust factor. There can
be a different adjust factor for both flow directions.
When operating around zero flow, it possible that this factor is
constantly switching from positive adjust factor to negative adjust
factor.
Voffset Correction - It is possible to put a fixed velocity offset in
the meter. This will normally only be used on special projects. The
standard for this factor is 0 m/s.
