Signal Processing - Siemens SITRANS LR560 Operating Instructions Manual

2.3.6.2.
Defines the maximum rate at which the reported sensor value is allowed to
increase. Allows you to further adjust the SITRANS LR560 response to
increases in the actual material level. Fill Rate is automatically updated
whenever Response Rate (2.3.6.1.) is altered.
Options

Enter a value slightly greater than the maximum vessel-filling rate, in units
per minute.
2.3.6.3.
Defines the maximum rate at which the reported sensor value is allowed to
decrease. Adjusts the SITRANS LR560 response to decreases in the actual
material level. Empty Rate is automatically updated whenever Response
Rate (2.3.6.1.) is altered.
