Parameter name Description
Level selection (024)
Options
Select the method for calculating the level
Options:
• In pressure
If this option is selected, specify two pressure/level value pairs. The level value is
displayed directly in the unit that you select via the "Unit before lin. (025)"
parameter.
• In height
If this option is selected, specify two height/level value pairs. From the measured
pressure, the device first calculates the height using the density. This
information is then used to calculate the level in the "Unit before lin. (025)"
selected using the two value pairs specified.
Factory setting:
In pressure
Unit before lin. (025)
Options
Select the unit for the measured value display for the level before linearization.
The unit selected is only used to describe the measured value. This means that the
measured value is not converted when a new output unit is selected.
Example:
• Current measured value: 0.3 ft
• New output unit: m
• New measured value: 0.3 m

Height unit (026)
Options
Select the height unit. The measured pressure is converted to the selected height
unit using the "Adjust density (034)" parameter.

Calibration mode (027)
Options
Select the calibration mode.
Options:
•Wet
Wet calibration takes place by filling and emptying the container. In the case of
two different levels, the level, volume, mass or percentage value entered is
assigned to the pressure measured at this point in time ("Empty calib. (028)" and
"Full calib. (031)" parameters).
•Dry
Dry calibration is a theoretical calibration. For this calibration, you specify two
pressure/level value pairs or height/level value pairs via the following
parameters: "Empty calib. (028)", "Empty pressure (029)", "Full calib. (031)", "Full
pressure (032)" , "Empty height (030)", "Full height (033)".
Factory setting:
