Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus Level measurement (FF configuration program)
Endress+Hauser 15
5.2 "Level easy pressure" level selection
5.2.1 Calibration with reference pressure – wet calibration
Example:
In this example, the level in a tank should be measured in m. The maximum level is 3 m (9.8 ft).
The pressure range is set to 0-300 mbar (4.5 psi).
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• The tank can be filled and emptied.
!
Note!
• See also Operating Instructions for Deltabar S (BA00301P) or Cerabar S (BA00302P), "Level
measurement" section or Deltapilot S (BA00372P), "Level measurement" section.
• The values entered for Empty Calib. Level Easy/EMPTY_CALIBRATION_EASY and Full Calib.
Level Easy/FULL_ CALIBRATION_EASY must be at least 1% apart for the "Level Easy Pressure"
level mode. 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.
• Due to the orientation of the device, there may be a shift in the measured value, i.e. when the
container is empty, the MEASURED VALUE parameter does not display zero.
