6.11.2 Information on level measurement
!
Note!
You have a choice of two methods for calculating the level: "In pressure" and "In height". The table
in the "Overview of level measurement" section that follows provides you with an overview of these
two measuring tasks.
• The limit values are not checked, i.e. the values entered must be appropriate for the sensor and
the measuring task for the device to be able to measure correctly.
• Customer-specific units are not possible.
• The values entered for "Empty calib./Full calib.", "Empty pressure/Full pressure", "Empty height/
Full height" and "Set LRV/Set URV" must be at least 1% apart. The value will be rejected, and a
message output, if the values are too close together.

Calibration takes place
by entering two
pressure/level value

level, volume or
mass units.

measured value.
Calibration takes place
by entering the density
and two height/level
value pairs.
