Information on level measurement
• A Quick Setup menu is available for each of the measuring modes Pressure and Level
which guides you through the most important basic functions.
For the "Level" Quick
• Furthermore, three level modes are available for the level measurement, namely "Level
easy pressure", "Level easy height" and "Level standard". For the "Level standard" level mode,
you can choose between the "Linear", "Pressure linearized" and "Height linearized" level
types. The table in the "Overview of level measurement" section that follows provides you
with an overview of the various measuring tasks.
– 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
CALIBRATION/FULL CALIBRATION, EMPTY PRESSURE/FULL PRESSURE and EMPTY
HEIGHT/FULL HEIGHT have to be at least 1% apart. The value will be rejected with a
warning 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.
– The "Level easy pressure" and "Level easy height" level modes comprise fewer parameters
than the "Level standard" mode and are not 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.
• For a detailed description of the parameters and configuration examples, see Operating
Instructions BA00303P "Cerabar S/Deltabar S/ Deltapilot S, Description of Device
Functions".
WARNING
!
Changing the measuring mode affects the span (URV)!
This situation can result in product overflow.
‣
If the measuring mode is changed, the span setting (URV) must be verified in the
"Calibration"
"Basic Setup" operating menu and, if necessary, reconfigured!
