5.7.2 Empty and full calibration
Parameter Remarks
"empty calibration" Use this parameter to specify the empty distance E, i.e. the distance between the reference
point of the sensor and the minimum level (zero point).
Notice!
Value of zero will not be displayed, if zero point is set too low.
If the zero point is set below the tank bottom, a level value greater than zero is displayed
even when the tank is empty. The zero point should not be deeper than the point at which
the ultrasonic wave impinges on the tank bottom.
BD Blocking distance
D Distance from reference point of the sensor to fluid surface
EEmpty distance
F Span (full distance)
L Level
V Volume (or mass)
" full calibration" Use this parameter to specify the span F, i.e. the distance from the minimum level to the
maximum level. The maximum level may not project into the blocking distance
"blocking distance" Indicates the blocking distance of the respective sensor. The blocking distance is measured
from the reference point of the respective sensor.
