For readings in volumetric units instead of percentage values:
1.
Select a volumetric unit from PV Units (volume/level) (2.3.3.) .
2. Enter the vessel volume corresponding to High Calibration Point.
Vessel Dimension A (2.4.1.3.)
The height of the vessel bottom in Level Units when the bottom is conical, pyramidal,
parabolic, spherical, or flat -sloped. If the vessel is horizontal with parabolic ends, the depth
of the end. See Vessel Shape (2.4.1.1.) for an illustration.
Values Range: 0.0000 to 999999 in Level Units
Default: 0.0
Related Parameters Vessel Shape (2.4.1.1.)
Dimension L (2.4.1.4.)
Length of the cylindrical section of a horizontal parabolic end vessel, in Level Units. See
Vessel Shape (2.4.1.1.) for an illustration.
Values Range: 0.0000 to 999999 in Level Units
Default: 0.0
Related Parameters Vessel Shape (2.4.1.1.)
XY index (2.4.1.5.)
Level/Volume breakpoints allow you to define a complex vessel shape as a series of
segments. A value is assigned to each level breakpoint and a corresponding value is assigned
to each volume breakpoint.
Volume values are defined in volume units and can be percent or volumetric; level values are
defined in level units, and can be percent or linear.
Level values Range: 0.0000 to 999999 (m, cm, mm, ft, in, %)
Default: 0.0
Volume values Range: 0.0000 to 999999 (% or volumetric units)
Default: 0.0
Enter up to 32 level breakpoints, where the corresponding volume is known. The values
corresponding to 100% and 0% levels must be entered. The breakpoints can be ordered from
top to bottom, or the reverse.
