Density unit (127)
Display
Displays the density unit. The measured pressure is converted to a height using the
"Height unit (026)" and "Adjust density (034)" parameters.
Factory setting:
•g/cm
3
Adjust density (034)
Entry
Enter the density of the medium. The measured pressure is converted to a height
using the "Height unit (026)" and "Adjust density (034)" parameters.
Factory setting:
1.0
Process density (035)
Entry
Enter a new density value for density correction.
The calibration was carried out with water as the medium, for example. Now the
container is to be used for another medium with another density. The calibration is
corrected appropriately by entering the new density value in the "Process density
(035)" parameter.
If you change to dry calibration after completing a wet calibration using the
"Calibration mode (027)" parameter, the density for the "Adjust density (034)" and
"Process density (035)" parameters must be entered correctly before changing the
calibration mode.
Factory setting:
1.0
Level before lin. (019)
Display
Displays the level value prior to linearization.
Parameter name Description
Lin. mode (037)
Options
Select the linearization mode.
Options:
•Linear
The level is output without being converted beforehand. "Level before lin. (019)"
is output.
• Erase table
The existing linearization table is deleted.
• Manual entry (sets the table to the edit mode, an alarm is output):
The value pairs of the table ("X-value (040) (manual entry)" and "Y-value (041)
(manual entry/in semi-auto. entry)") are entered manually.
• Semiautomatic entry (sets the table to the edit mode, an alarm is output):
The container is emptied or filled in stages in this entry mode. The device
records the level value automatically ("X-value (040) (manual entry)"). The
associated volume, mass or %-value is entered manually ("Y-value (041)
(manual entry/in semi-auto. entry)").
•Activate table
The table entered is activated and checked with this option. The device shows
the level after linearization.
Factory setting:
