Use a setting just faster than the maximum filling or emptying rate (whichever is faster).
Fill Rate per Minute (2.4.2.)
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 is altered.

Units (2.2.1.)
Enter a value slightly greater than the maximum vessel-filling rate, in units per minute.
Sensor value is the value produced by the echo processing which represents the distance from
sensor reference point to the target. See
Sensor Mode (2.2.2.)
for an illustration.
