Parameters
2.7.1.2. Maximum Volume
The maximum volume of the vessel. Enter the vessel volume corresponding
to High Calibration Point. For example, if your maximum vessel volume is
8000 L, enter a value of 8000. Volume units are defined by the user but are
not explicitly stated in the SITRANS LR250
2.7.1.3. Dimension A
The height of the vessel bottom 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 (2.7.1.1.) for an illustration.
2.7.1.4. Dimension L
Length of the cylindrical section of a horizontal parabolic end vessel. See
Vessel Shape (2.7.1.1.) for an illustration.
2.7.2. Table 1-8
If your vessel shape is more complex than any of the preconfigured shapes, you
can define the shape as a series of segments. A value is assigned to each level
breakpoint and a corresponding value is assigned to each volume breakpoint.
Level values are defined in Units (2.2.1.). Volume units are defined by the user
but are not explicitly stated in the SITRANS LR250.
