Access: OOS
Select the level mode.
Prerequisite:
• Measuring Mode = Level
!
Note!
• With regard to the "Level easy pressure" and "Level easy height" level modes, the values
entered are not tested as extensively as in the "Level standard" level mode. In the "Level
easy pressure" and "Level easy height" level modes, the values entered for Empty Calib./
EMPTY_CALIBRATION, Full Calib./FULL_CALIBRATION, Empty Pressure Level Easy/
EMPTY_PRESSURE_EASY,Full Pressure Level Easy/FULL_PRESSURE_EASY, Empty
Calib. Level Easy/EMPTY_CALIBRATION_EASY, Full Calib. Level Easy/
FULL_CALIBRATION_EASY must be at least 1% apart.
The value will be rejected with a message if the values are too close together. Further limit
values are not checked; i.e. the values entered must be appropriate for the sensor and the
measuring task so that the measuring device can measure correctly.
→ For an overview of the different level modes and types, see → ä 14 Section 5.1 and
→ ä 105 Section 9.1 "Overview of level measurement".
• The "Level easy pressure" and "Level easy height" level modes comprise fewer parameters
than the "Level standard" mode and are used to quickly and easily configure a level
application.
• Customer-specific units of level, volume and mass, or a linearization table, can only be
entered in the "Level standard" level mode.
Prerequisite:
• Level easy pressure
You specify two pressure-level value pairs for this level mode. The pressure measured
value is converted directly to the unit which is selected via the Output Unit Level Easy/
OUTPUT_UNIT_EASY parameter (→ ä 73. The two calibration modes, "Wet" and "Dry",
are available.
– 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.
– Dry calibration is a theoretical calibration. For this calibration, you specify two pressure-
level value pairs via the Empty Calib. Level Easy/EMPTY_CALIBRATION_EASY,
Empty Pressure Level Easy/EMPTY_PRESSURE_EASY, Full Calib. Level Easy/
FULL_CALIBRATION_EASY and Full Pressure Level Easy/FULL_PRESSURE_EASY
parameters. Parameter description, see → ä 74
• Level easy height
For this level mode, you specify a height unit, the density and two height-level value pairs.
The pressure measured value is converted to a height value using the density entered and
the height unit. The two calibration modes, "Wet" and "Dry", are available.
– 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
converted height value.
– Dry calibration is a theoretical calibration. For this calibration, you specify two height-
level value pairs via the Empty Height Level Easy/EMPTY_HEIGHT_EASY, Empty
Calib. Level Easy/EMPTY_CALIBRATION_EASY, Full Height Level Easy/
FULL_HEIGHT_EASY and Full Calib. Level Easy/FULL_CALIBRATION_EASY
parameters.
→ Parameter description, see → ä 74
• Level standard
Once you have selected this level mode, you can use the Level Mode/LEVEL_MODE
parameter (
→ → ä 61) to choose between "Linear", "Pressure linearized" and "Height
linearized".
