Use a setting just faster than the maximum filling or emptying rate (whichever is faster).
Fill Rate per Minute (2.3.8.2.)
Defines the maximum rate at which the reported sensor value is allowed to decrease. Allows
you to adjust the SITRANS LR250 response to decreases in the actual material level. Fill Rate is
automatically updated whenever
Response Rate (2.3.8.1.)
is altered.
Sensor value is the value produced by the echo processing which represents the distance
from sensor reference point to the target [see
Low Calibration Point (2.3.7.1.)
for an
illustration].

Level Unit (2.3.2.)
Enter a value slightly greater than the maximum vessel-filling rate, in units per minute.
Empty Rate per Minute (2.3.8.3)
Defines the maximum rate at which the reported sensor value is allowed to increase. Adjusts
the SITRANS LR250 response to increases in the actual material level. Empty Rate is
automatically updated whenever Response Rate is altered
.
