Baseline viewer gauge valuesTable 7-2:
Value Description
Avg Velocity Displays the average flow velocity for the meter. This gauge contains no
green zone.
Profile Factor Displays the velocity flow profile factor for the meter. The profile factor is
calculated from the chordal velocities as ((VelocityB+VelocityC)/(Veloci-
tyA+VelocityD)). The green zone is centered on the profile factor set in
the baseline ± the percentage defined by Profile factor limit configurable
in the Field Setup Wizard on the Continuous Flow Analysis page.
Swirl Angle Displays the swirl angle in degrees for the meter. The green zone is cen-
tered on the swirl angle set in the baseline ± 5%.
Symmetry Displays the symmetry for the meter. The symmetry is calculated from
the chordal velocities as ((VelocityA+VelocityB)/(VelocityC+VelocityD)).
The green zone is centered on the Symmetry set in the baseline ± the per-
centage defined by Symmetry limit configurable in the Field Setup Wizard
on the Continuous Flow Analysis page.
Cross-Flow Displays the cross-flow for the meter. The cross-flow is calculated from
the chordal velocities as ((VelocityA+VelocityC)/(VelocityB+VelocityD)).
The green zone is centered on the cross-flow set in the baseline ± the per-
centage defined by Cross-flow limit configurable in the Field Setup Wiz-
ard on the Continuous Flow Analysis page.
Turbulence A through
D
Displays the percent turbulence values for each path of the meter. The
green zone extends for 0% to the Chord turbulence limit configurable in
the Field Setup Wizard on the Continuous Flow Analysis page.
Display Description
1-minute averages Selecting 1-minute averages will make the gauges display a one minute
rolling average. Next to this selection will be an indication if the one mi-
nute average values are valid or invalid. For the averages to be valid, the
meter must meet the following criteria for at least one full minute: flow-
ing in only one direction, no chord failures or inactive chords present and
flowing within the Flow limits configurable in the Field Setup Wizard on
the Continuous Flow Analysis page.
Current values Displays the most recently calculated values.
