SITRANS LR250 (FOUNDATION FIELDBUS)
Operating Instructions, 01/2014, A5E32221411-AB
137
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
.
