4 Pressure measurement
4.1 Calibration with reference pressure
Example:
In this example, a device with a 500 mbar (7.5 psi) sensor is configured for the 0...+300
mbar (4.5 psi)measuring range, i.e. 0 mbar and 300 mbar (4.5 psi) are assigned to the 4 mA
value and 20 mA value respectively.
Prerequisite:
• The pressure values 0 mbar and 300 mbar (4.5 psi) can be specified. The device is already
installed, for example.
• See also Operating Instructions Deltabar S (BA00270P), Section "Differential pressure
measurement", Cerabar S (BA00271P), Section "Pressure measurement" or Deltapilot S
(BA00332P), Section "Pressure measurement".
• For a description of the parameters mentioned, see
– Page 62, Table 2: MEASURING MODE

– Page 69, Table 7: BASIC SETUP.
• For a description of further relevant parameters, see
– Page 100, Table 15: EXTENDED SETUP
– Page 120, Table 25: PROCESS VALUES.
Changing the measuring mode can affect the adjustment data!
This situation can result in product overflow.

The measured variable is in
direct proportion to the
measured pressure.
Calibration is performed by
entering two pressure-level
value pairs.
The measured variable is in
direct proportion to the
measured pressure.
Calibration is performed by
entering the density and
two height-level value
pairs.
The measured variable is in
direct proportion to the
measured pressure.
The measured variable is
not in direct proportion to
the measured pressure as,
for example, with
containers with a conical
outlet. A
linearisation table must be
entered for the calibration.
– Two measured variables
are required or
– The container shape is
given by value pairs, such
as height and volume.
The 1st measured variable
%-height or height must be
in direct proportion to the
measured pressure. The
2nd measured variable
volume, mass or % must
not be in direct proportion
to the measured pressure.
A linearisation table must
be entered for the 2nd
measured variable. The 2nd
measured variable is
assigned to the 1st
measured variable by
means of this table.

5.2 "Level Easy Pressure" level selection
5.2.1 Calibration with reference pressure – wet calibration
Example:
In this example, the level in a tank should be measured in m. The maximum level is 3 m (9.8
ft). The pressure range is set to 0 to 300 mbar (4.5 psi).
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• The tank can be filled or emptied.
• See also Operating Instructions for Deltabar S (BA00270P) or Cerabar S (BA00271P),
Section "Level measurement" or Deltapilot S (BA00332P), Section "Level measurement".
• The values entered for EMPTY CALIB./FULL CALIB. and SET LRV/SET URV must have a
minimum interval of 1% for the "Level Easy Pressure" level mode. The value will be rejected
with a warning message if the values are too close together. Further limit values are not
checked; i.e. the values entered must be appropriate for the sensor and the measuring task
so that the measuring device can measure correctly.

5.2.2 Calibration without reference pressure – dry calibration
Example:
In this example, the volume in a tank should be measured in litres.The maximum volume of
1000 litres (264 US gal) corresponds to a pressure of 450 mbar (6.75 psi). The minimum
volume of 0 litres corresponds to a pressure of 50 mbar (0.75 psi), as the device is mounted
below the level lower range value. The device is mounted below the level lower range value.
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• This is a theoretical calibration i.e. the pressure and volume values for the lower and upper
calibration point must be known.
• See also Operating Instructions for Deltabar S (BA00270P) or Cerabar S (BA00271P),
Section "Level measurement" or Deltapilot S (BA00332P), Section "Level measurement".
• The values entered for EMPTY CALIB./FULL CALIB. and SET LRV/SET URV must have a
minimum interval of 1% for the "Level Easy Pressure" level mode. The value will be rejected
with a warning message if the values are too close together. Further limit values are not

5.3.2 Calibration without reference pressure – dry calibration
Example:
In this example, the volume in a tank should be measured in litres. The maximum volume is
1000 l (264 US gal), and the maximum height is 4.5 m (15 ft). The minimum volume of 0
litres corresponds to a level of 0.5 m (1.6 ft), as the device is mounted below the level lower
range value. The density of the fluid is 1 kg/dm
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• This is a theoretical calibration i.e. the height and volume values for the lower and upper
calibration point must be known.
• See also Operating Instructions for Deltabar S (BA00270P) or Cerabar S (BA00271P),
Section "Level measurement" or Deltapilot S (BA00332P), Section "Level measurement".
• The values entered for EMPTY CALIB./FULL CALIB., EMPTY PRESSURE/FULL PRESSURE,
EMPTY HEIGHT/FULL HEIGHT and SET LRV/SET URV must have a minimum interval of
1% for the "Level Easy Height" level mode. The value will be rejected with a warning
message if the values are too close together. Further limit values are not checked; i.e. the
values entered must be appropriate for the sensor and the measuring task so that the
measuring device can measure correctly.
• Due to the orientation of the device, there may be a shift in the measured value, i.e. when
the container is empty, the MEASURED VALUE parameter does not display zero. To
perform a position adjustment see also Page , Table 6: Position adjustment.
• For a description of the parameters mentioned, see

is larger than the minimum span.
4. A level value is assigned to both the lower and upper current value with the SET LRV
( Page 102) and SET URV (Page 102) parameters.
You can use the ASSIGN CURRENT parameter (Page 114) to specify whether the
current output should depict the 1st or 2nd measured variable. Depending on the
setting of the ASSIGN CURRENT parameter, enter the following values for SET LRV and
SET URV:
– ASSIGN CURRENT = tank content (factory setting) %-value, volume value or
mass value
– ASSIGNMENT = height level value
The following applies for the setting ASSIGN CURRENT "Tank content":
If you enter values for TANK CONTENT MIN (Page 104 or 107) and TANK CONTENT
MAX ( Page 104 or 107), the SET LRV and SET URV parameters are also changed. If
you want to assign values other than those for TANK CONTENT MIN and TANK
CONTENT MAX to the lower and upper current values, the desired values must be
entered for SET LRV and SET URV.
The following applies for the setting ASSIGN CURRENT "Height":
If you enter values for LEVEL MIN (Page 93) and LEVEL MAX (Page 93), the SET
LRV and SET URV parameters are also changed. If you want to assign values other than
those for LEVEL MIN and LEVEL MAX to the lower and upper current values, the
desired values must be entered for SET LRV and SET URV.

5.6.2 Dry calibration and manual entry of the linearisation table
Example:
In this example, the height and the volume should be measured at the same time.
Prerequisite:
• This is a theoretical calibration, i.e. the points for the linearisation table are known.
• A minimum gap of 0.5 % of the distance between two points must be maintained. Spans
for the "Pressure linearized" option: HYDR. PRESS MAX. – HYDR. PRESS MIN.; TANK
CONTENT MAX. – TANK CONTENT MIN. Spans for the "Height linearized" option: LEVEL
MAX – LEVEL MIN; TANK CONTENT MAX. – TANK CONTENT MIN.
• See also Operating Instructions for Deltabar S (BA00270P) or Cerabar S (BA00271P),
Section "Level measurement" or Deltapilot S (BA00332P), Section "Level measurement".
• Due to the orientation of the device, there may be a shift in the measured value, i.e. when
the container is empty, the MEASURED VALUE parameter does not display zero. To
perform a position adjustment see also Page 68, Table 6: Position adjustment.
