P46 is the distance between the sensor face and the surface of the liquid measured at the limit of flow initiation (Q = 0); see figures (P06 = 0).

Output signals of arbitrary characteristics can be assigned to the level values measured by the device. The characteristics can be specified with a
maximum of 100 points. Using linear interpolation, the device calculates the output signal from the measured level between points. This can be
used for, e.g., assigning the measured level to an arbitrary output signal or calculating the level/volume of a tank that is not in the selectable shapes
(e.g., dented).
