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
Related Parameters
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
Related Parameters
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
Volume values
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.
