Enter the appropriate distance value in m (corresponding to the
percentage value) for the full vessel. The distance refers to the sensor
reference plane (seal surface of the process fitting). Keep in mind that
the max. level must lie below the dead band.
In this menu item, you can enter the min. adjustment for the level.
Adjust the requested percentage value with [+] and store with [OK].
Enter the suitable distance value in m for the empty vessel (e.g.
distance from the flange to the probe end) corresponding to the per-
centage value. The distance refers tot he sensor reference plane (seal
surface of the process fitting).
The following circumstances cause interfering reflections and can
influence the measurement:
•
High sockets
•
Vessel installations such as struts
•
Deflectors, etc.
Note:
A false signal suppression is only recommended with liquid applica-
tions.
A false signal suppression detects, marks and saves these false sig-
nals so that they are no longer taken into account for level measure-
ment.
This should be done with the lowest possible level so that all potential
interfering reflections can be detected.
Proceed as follows:
