Level measurement (ToF Tool) Cerabar S/Deltabar S

Note!
1. For this level type, the measured variables "height + %", "height + volume", "height + mass",
"%-height + %", "%-height + volume" and "%-height + mass" are available. → See Page 117 ff.
2. You can also specify customer-specific units. See parameter description for PRESS. ENG. UNIT
(→ Page 102), HEIGHT UNIT (→ Page 117), UNIT VOLUME (→ Page 118) and MASS UNIT
(→ Page 119).
3. Once you have entered the maximum level to be expected for LEVEL MAX., the alarm "A707
X-Val of lin. table out of edit limits" can appear. At this stage, the linearisation table already
consists of two points as standard. It could be the case that the 2nd value and thus the highest
X-VALUE of the linearisation table is greater than the maximum level entered. The message
disappears as soon as the highest X-VALUE is greater than the maximum level and the table
entered is active.
4. You can use the MENU DESCRIPTOR parameter (→ Page 136) to specify which measured
value should be displayed on the on-site display.
18 Select the "Editor table" option by means of the TABLE
SELECTION parameter.
P01-PMP75xxx-19-xx-xx-xx-005
P01-xxxxxxxx-05-xx-xx-xx-018

5 See table, step 16.
6 See table, step 17.
7 See table, steps 18 to 22.
19 Select the "Semiautomatic" option by means of the LIN.
EDIT MODE parameter.
20 Select the "New table" option by means of the EDITOR
TABLE parameter. After confirming with "Enter," the
"Continue edit" option is displayed again.
21 Enter linearisation table (min. 2 points, max. 32 points).
Fill the tank to the height of the 1st point.
LINE-NUMB: confirm value displayed.
X-VAL.: the hydrostatic pressure present is measured
and converted to the corresponding level and displayed.
The X-VAL. displayed is saved by confirming the
Y-value. See following line, Y-VAL.
Y-VAL.: enter the volume value, here 0 m
3
for example,
and confirm the value.
22 You can enter further points for the linearisation table as
explained in step 21. Once all the points have been
entered, the table must be activated by means of the
TAB. ACTIVATE parameter.
23 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).
24 Result:
– The linearisation table has been entered.
– The measured value display and the
TANK CONTENT parameter display the 2nd
measured value (here the volume).
– The LEVEL BEFORE LIN parameter displays the 1st
measured value (here the height). See also the
following note, point 4.
