Expert È Measurement È Level
Parameter name Description
Level selection (024)
Selection
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 "Output unit" 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 "Output unit" selected using the two value pairs
specified.
Factory setting:
In pressure
Output unit (025)
Selection
Select the unit for the measured value display for the level before linearization.
!
Note!
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
Options
•%
• mm, cm, dm, m
•ft, inch

Height unit (026)
Selection
Select the height unit. The measured pressure is converted to the selected height unit
using the "Adjust density" parameter.
Prerequisite
"Level selection" = "In height"
Options
•mm
•m
•inch
•ft
Factory setting:
m
Calibration mode (027)
Selection
Select the calibration mode.
Options:
•Wet
Wet calibration takes place by filling and emptying the container. With two different
levels, the level, volume, mass or percentage value entered is assigned to the pressure
measured at this point in time ("Empty calibration" and "Full calibration" parameters).
•Dry
Dry calibration is a theoretical calibration. For this calibration, you specify two
pressure/level value pairs via the following parameters: "Empty calib.", "Empty
pressure", "Full calib.", "Full pressure".
Factory setting:
Wet
