6.8.5. Configuration:
This menu contains sub menus like Linearization, Correlation Algorithm, Volume & Echo curve as
shown in figure.
Linearization
This option allows users to adjust the level measurement to agree with a customer measurement.
It is available only through the use of a PC-based DTM / DD.
Configure the linearization table to make the transmitter output agree with an independent level
measurement.
Note: The Level Linearization feature does not affect the values reported for the Distance to Product
and Distance to Interface device variables. If Level Linearization checkbox is enabled, associated level
is no longer described solely by the basic geometry and it is possible that the Product Level will not be
equal to (Sensor Height – Level Offset – Distance to Product). Likewise for the Interface if is being
calculated.
Table should be entered either in ascending or descending order only.
Enable Linearization:
If enabled, linearization will convert the level as measured by the sensor to a corrected level value as
defined by the user in the linearization table on this page (max 32 points). This may be used to correct
for any non-linearity's that may occur. For example, a tank for which the roof height changes during
filling.
Wet Linearization:
When the measured level for the tank reaches a level where the corresponding corrected level is
known, select a row in the linearization table, enter the corrected level in the textbox below, and
proceed further. This will immediately set the values into the selected row in the strapping table (i.e.
immediately set in the transmitter).
