This next view shows other pipe outlines superimposed:
The smaller circle represents a 4" (100 mm) vertical pipe, which because the 7827 meter orientation is
constant irrespective of pipe orientation intersects the effective region. The 6" (150 mm) pipe is the
smallest pipe diameter to completely enclose the effective region when the pipe is vertical. Thus
smaller pipe diameters can lead to a variety of different geometries which would each require a
separate calibration.
An alternative condition is shown in the next diagram where the side pocket is extended until it passes
completely through the effective region producing a “core”:
