Level measurement (ToF Tool) Cerabar S/Deltabar S
80 Endress+Hauser
8.3 "Pressure linearized" level type
8.3.1 Semiautomatic entry of the linearisation table
Example:
In this example, the volume in a tank with a conical outlet should be measured in m
3
.
Prerequisite:
• The tank can be filled. The linearisation characteristic must rise continuously.

Description
1 Deltabar S: before configuring the device for your
application, the pressure piping must be cleaned and the
device filled with fluid. See Operating Instructions
BA301P, Section 6.6.1.
P01-PMP75xxx-19-xx-xx-xx-002
2 Carry out position adjustment if necessary. See Page 98,
ToF Tool, table 4: POSITION ADJUSTMENT.
Carry out basic setup:
3 If necessary, select the "Level" measuring mode via the
MEASURING MODE parameter.
Menu path: OPERATING MENU → SETTINGS →
BASIC SETUP → MEASURING MODE
4 Select a pressure unit via the PRESS. ENG. UNIT
parameter, here mbar for example.
5 Select the "Pressure linearized" option by means of the
LEVEL MODE parameter. See also the following note,
point 3.
6 Select the "Volume" option by means of the LINd.
MEASURAND parameter.
7 Select a volume unit via the UNIT VOLUME parameter,
here m
3
for example.
8 Select HYDR. PRESS MIN. parameter.
Enter the minimum hydrostatic pressure to be expected,
here 0 mbar for example.
9 Select HYDR. PRESS MAX
.
Enter the maximum hydrostatic pressure to be expected,
here 350 mbar for example.
