Use the Daniel MeterLink
components in Daniel Ultrasonic meter. When the dialog is first opened, the Currently
Installed Versions table will show the currently installed program components in the
meter.

Description
Displays the velocity flow profile factor for the meter. The profile factor is
calculated from the chordal velocities as ((VelocityB+VelocityC+VelocityF
+VelocityG)/(VelocityA+VelocityD+VelocityE+VelocityH)). 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.
Displays the swirl angle in degrees for the meter. The green zone is
centered on the swirl angle set in the baseline ± 5%.
Displays the symmetry for the meter. The symmetry is calculated from
the chordal velocities as ((VelocityA+VelocityB+VelocityE+VelocityF)/
(VelocityC+VelocityD+VelocityG+VelocityH)). The green zone is centered
on the Symmetry set in the baseline ± the percentage defined by
Symmetry limit configurable in the Field Setup Wizard on the
Continuous Flow Analysis page.
Displays the cross-flow for the meter. The cross-flow is calculated from
the chordal velocities as ((VelocityA+VelocityC+VelocityF+VelocityH)/
(VelocityB+VelocityD+VelocityE+VelocityG)). The green zone is centered
on the cross-flow set in the baseline ± the percentage defined by Cross-
flow limit configurable in the Field Setup Wizard on the Continuous Flow
Analysis page.
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.
Description
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 minute 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: flowing 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.
Displays the most recently calculated values.
