Linearization
Alinearizationisnecessaryforallvesselsinwhichthevesselvolume
doesnotincreaselinearlywiththelevel-e.g.ahorizontalcylindri-
cal or spherical tank, when the indication or output of the volume is
required.Correspondinglinearizationcurvesarepreprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.
Thelinearizationappliesforthemeasuredvalueindicationandthe
current output. By activating the suitable curve, the percentage vessel
volume is displayed correctly.
False signal suppression
Highsocketsandinternalvesselinstallationscauseinterferingreec-
tionsandcaninuencethemeasurement.
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
reectionscanbedetected.
Enter the actual distance from the sensor to the product surface.
All interfering signals in this section are detected by the sensor and
stored.
The instrument carries out an automatic false signal suppression
as soon as the probe is uncovered. The false signal suppression is
always updated.
6.5 Parameter adjustment - Extended adjustment
For technically demanding measuring points, you can carry out
extended settings in "Extendedadjustment".
Themainmenuisdividedintovesectionswiththefollowingfunc-
tions:
Setup: Settings, e.g. medium, application, vessel, adjustment, damp-
ing,deviceunits,unitSV2,falsesignalsuppression,linearization
Display: Language setting, settings for the measured value indication
as well as lighting
