Cerabar S/Deltabar S Level measurement (FF configuration program)
Endress+Hauser 11
!
Note!
1. For this level type, the measured variables %, volume and mass are available. → See Page 40 ff.
2. You can also specify customer-specific units. See parameter descriptions for CAL_UNIT
(→ Page 34), HEIGHT_UNIT (→ Page 41), VOLUME_UNIT (→ Page 42) and MASS_UNIT
(→ Page 43).
Description
Carry out linearisation:
P01-xxxxxxxx-05-xx-xx-xx-015
Fig. 2: Semiautomatic entry of the linearisation
table
1 See Table, Step 9.
2 See Table, Step 10.
3 See Table, Step 11.
4 See Table, Step 12.
5 See Table, Steps 13 to 16.
11 Select SCALE_OUT parameter, EU_0 element.
Specify the minimum tank contents to be expected, here
0 m
3
for example.
12 Select SCALE_OUT parameter, EU_100 element.
Specify the maximum tank contents to be expected, here
3.5 m
3
for example. See also the following note, point 4.
13 Select the "Semiautomatic" option by means of the
LINEARIZATION_TABLE_MODE/LIN. EDIT MODE
parameter.
14 Select the "Edit table" option by means of the
TAB_OBCODE/TABLE SELECTION parameter.
15 Enter linearisation table (min. 2 points, max. 32 points).
Fill the tank to the height of the 1st point.
TAB_ENTRY: enter the value of the corresponding point.
The PRESSURE_1_AFTER_DAMPING/PRESSURE
parameter displays the measured hydrostatic pressure.
This hydrostatic pressure displayed is saved by
confirming the Y-value. See the following line.
TAB_XY_VALUE, 2nd element (Y-value): enter the
volume value, here 0 m
3
for example, and confirm the
value.
16 You can enter further points for the linearisation table as
explained in Step 15. The previous point first has to be
saved in the linearisation table before the next point can
be entered. In other words, a complete linearisation table
cannot be saved to the device. Once all the points have
been entered, the table must be activated by means of
the TAB_OBCODE/TABLE SELECTION parameter.
17 Set the Pressure Transducer Block to the "Auto" block
mode.
18 If necessary, use the Analog Input Block to configure the
CHANNEL parameter (→ Page 67), L_TYPE parameter
(→ Page 69), XD_SCALE parameter (→ Page 73) and
OUT_SCALE parameter (→ Page 71).
19 Result:
The linearisation table is entered and the measuring
device is ready for level measurement.
