Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus Level measurement (via local operation and FieldCare)
Endress+Hauser 107
!
Note!
1. You can also perform calibration with reference pressure by means of the QUICK SETUP
menu. → ä 138 ff, Table 4: QUICK SETUP "Level".
2. For this level mode, the measured variables %, level, volume and mass are available. → See
also parameter description for OUTPUT UNIT, → ä 148.
3. If operating via the local operation, the EMPTY CALIB. (010) (→ ä 149) and FULL CALIB.
(004) (→ ä 149) parameters also show the pressure present at the device. For operation using
FieldCare, the pressure present at the device is displayed in the PROCESS VALUES group.
5 Local operation:
Select the BASIC SETUP function group. Menu path:
GROUP SELECTION → OPERATING MENU →
SETTINGS → BASIC SETUP

1 See Table, Step 9.
2 See Table, Step 10.
6 Select a pressure unit via the PRESS. ENG. UNIT
parameter, here mbar for example.
7 Select a level unit via the OUTPUT UNIT parameter,
here m for example.
8 Select the "Wet" option by means of the CALIBRATION
MODE parameter.
9 The hydrostatic pressure for the lower calibration point is
present at the device, here 0 mbar for example.
Select the EMPTY CALIB. parameter.
Enter the level value, here 0 m for example. The
pressure value present is assigned to the lower level
value by confirming the value.
10 The hydrostatic pressure for the upper calibration point is
present at the device, here 300 mbar (4.5 psi) for
example.
Select the FULL CALIB. parameter.
Enter the level value, here 3 m (9.8 ft) for example. The
pressure value present is assigned to the upper level
value by confirming the value.
11 Result:
The measuring range is set for 0 to 3 m (9.8 ft).
