General Operation
2. Enter the curve values from this chart into level and volume breakpoint tables (see

3. Ensure extra points are added around sharp transitions in the vessel volume (e.g:
steps in a well wall).
Example chart (with 15 of possible 32 Level and Volume breakpoints defined):
Note: If breakpoints are entered via LUI, then an upload is performed via PDM, a
second upload via PDM may be necessary to transfer the breakpoint values.
Note: The end points in the curve are 0,0 (fixed) and the point defined by
Maximum Level and Maximum Volume.
