Parameters
2.2.6.2. Fill Rate
Defines the maximum rate at which the reported sensor value is allowed to
increase. Allows you to further adjust the SITRANS LR250 response to
increases in the rate at which the vessel fills. Fill Rate is automatically
updated whenever Response Rate (2.2.6.1.) is altered.
Enter a value slightly greater than the maximum vessel-filling rate, in
Sensor Units per minute.
2.2.6.3. Empty rate
Defines the maximum rate at which the reported sensor value is allowed to
decrease. Adjusts the SITRANS LR250 response to decreases in the rate at
which the vessel empties. Empty Rate is automatically updated whenever
Response Rate (2.2.6.1.) is altered
.
Enter a value slightly greater than the vessel’s maximum emptying rate, in
Sensor Units per minute.
2.2.7. Transducer Block Values
Read only. Allows you to view TB values for diagnostic purposes
2.2.7.1. Main Output (PV– Primary Value)
The value for level, or volume (if volume conversion is selected).
In SIMATIC PDM, open the menu View – Display, and select the tab
Measured Value (Secondary Values). Refer to Volume/Level field.
