5 Level measurement (FF configuration program)
In this chapter the parameter text as well as the parameter name are indicated. In FF configuration
programs only the parameter text is displayed (exeption: in the NI-FBUS configurator you can select
if the parameter text or the parameter name is displayed).

Description Measured value display
The measured variable is
in direct proportion to the
measured pressure.
LEVEL SELECTION:
Level easy pressure
– % (level)
– Level
–Volume
–Mass
Linear Calibration without
reference pressure – dry
calibration, see → ä 25,
→ Chap. 5.4.2
The measured value display and
the Primary Value Type/
PRIMARY_VALUE and Level
Before Lin./LEVEL_BEFORE_
LINEARISATION parameters
display the measured value.
The measured variable is
not in direct proportion to
the measured pressure as
is the case with tanks with
a conical outlet, for
example. A linearization
table has to be entered for
the calibration.
LEVEL SELECTION:
Level standard/
LEVEL MODE:
Pressure linearized
– Pressure and %
– Pressure and
volume
– Pressure and mass
Pressure linearized – Calibration with
reference pressure:
semiautomatic entry of
linearization table, see
→ ä 27,
→ Chap. 5.5.1.
– Calibration without
reference pressure:
manual entry of
linearization table, see
→ ä 29,
→ Chap. 5.5.2.
The measured value display and
the Primary Value Type/
PRIMARY_VALUE parameter
show the measured value.
– Two measured variables
are required or
– The container shape is
given by value pairs,
such as height and
volume.
The 1st measured variable
%-height or height must be
in direct proportion to the
measured pressure. The
2nd measured variable
volume, mass or % must
not be in direct proportion
to the measured pressure.
A linearization table has to
be entered for the 2nd
measured variable. The
2nd measured variable is
assigned to the 1st
measured variable by
means of this table.
LEVEL SELECTION:
Level standard/
LEVEL MODE:
Height linearized
–Height and volume
–Height and mass
–Height and %
– %-height and
volume
– %-height and mass
– %-height and %
Height linearized – Calibration without
reference pressure: dry
calibration and manual
entry of linearization
table, see → ä 31,
→ Chap. 5.6.1.
The measured value display and
the Primary Value Type/
PRIMARY_VALUE parameter
show the 2nd measured value
(volume, mass or %).
The Level Before Lin./LEVEL_
BEFORE_LINEARISATION
parameter displays the 1st
measured value (%-height or
height).
