4.2.3.3 Echo Motion (F = off)
Evaluate echo motion
Value
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1.
Dynamic processes in the vessel are included in the evaluation of the measuring targets.
The typical filling speed can be set in Parameter 4.2.2.5. If the measured value still does
not follow the level height, switching off echo motion may improve the result.
4.2.3.4 Window Tracking (F = Off)
Value
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1. A
window follows the measured value which it is forced to track. The window size is
calculated from the set filling speed. Switch off window tracking for applications where
SITRANS LR400 is unable to keep up to level changes. By using SIMATIC PDM, you can
display a list of all echoes in your vessel. It provides the distance between the flange and
the measuring medium's surface, as well as the distances of fixed targets. These echoes
may be directly used and transferred to the fix distance list.
4.2.3.5 Tank Empty Detect (for qualified personnel only)
This parameter is for Factory Authorized Personnel only.
This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1.
4.2.3.6 Auto Fix Distance (for qualified personnel only)
This parameter is for Factory Authorized Personnel only.
4.2.3.7 Fix Distance List (for qualified personnel only)
This parameter is for Factory Authorized Personnel only.
4.2.3.7.1 to 4.2.3.7.9 Fix Distance Values (for qualified personnel only)
These parameters are for Factory Authorized Personnel only
4.2.3.8 Auto False-Echo Suppression (F = Use)
Learns and records the current signal up to the suppression distance setting. These
signals are then ignored during operation.
