Figure 7-9
The tape reading at the height of the reading
index of the instrument is indicating the distance
between the reaction point and the reading index.
If the instrument is installed in such a way that the
reading index is at the same level as the zero-
ullage reference level the reading of the tape
corresponds to the ullage providing the reaction
point of the sensing probe is positioned at the
liquid level.
If the reading index is positioned below or above
the reference level a positive or negative
correction of the tape reading is necessary.

gauging system”.
