If you have selected "No", you can enter the adjustment for the inter-
face measurement separately.
Enter the respective distance value in m for the empty vessel cor-
responding to the percentage value.
The following circumstances cause interfering reflections and can
influence the measurement:
•
High sockets
•
Vessel installations such as struts
Note:
A false signal suppression detects, marks and saves these false
signals so that they are no longer taken into account for the level and
interface measurement. We generally recommend carrying out a false
signal suppression to achieve the best possible accuracy. This should
be done with the lowest possible level so that all potential interfering
reflections can be detected.
Proceed as follows:
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
echo. The filling level would then no longer be detectable in this area.
If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":
