Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus Level measurement (via local operation and FieldCare)
Endress+Hauser 115
!
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. You can also specify customer-specific units. See parameter descriptions for PRESS. ENG.
UNIT (060) (→ ä 155), HEIGHT UNIT (708) (→ ä 158), UNIT VOLUME (313) (→ ä 159)
and MASS UNIT (709) (→ ä 160).
3. For this level mode, the measured variables %, level, volume and mass are available. → ä 158
ff.
4. The EMPTY PRESSURE (710) (→ ä 161) and FULL PRESSURE (711) (→ ä 161) parameters
display the pressure values belonging to the EMPTY CALIB. and FULL CALIB. parameters.
5 Local operation:
Select the BASIC SETUP function group. Menu path:
GROUP SELECTION → OPERATING MENU →
SETTINGS → BASIC SETUP
P01-xxxxxxxx-05-xx-xx-xx-011
1 See Table, Step 11.
2 See Table, Step 12.
6 Select a pressure unit via the PRESS. ENG. UNIT
parameter, here mbar for example.
7 Select the "Linear" option by means of the LEVEL MODE
parameter.
8 Select the "Level" option by means of the LIN.
MEASURAND parameter.
9 Select a level unit via the HEIGHT UNIT parameter, here
m for example.
10 Select the "Wet" option by means of the CALIBRATION
MODE parameter.
11 The 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.
12 The 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.
14 Result:
The corresponding pressure value has been assigned to
the lower and upper level value. The device is ready for
level measurement.
