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. See
Level Unit (2.3.2.)
and
PV Units
(volume/level) (2.3.3.)
.
Level values

Enter up to 32 level breakpoints, where the corresponding volume is known. The values
