authorized specialists (e.g. electrical technicians) in full compliance with the instructions in
this manual, the applicable norms, legal regulations and certificates (depending on the
application).
• The specialist must have read and understood this manual and must follow the instructions it
contains. If you are unclear on anything in these Brief Operating Instructions, you must read
the Operating Instructions (on the CD-ROM). The Operating Instructions provide detailed
information on the device/measuring system.

3 Installation
3.1 General installation instructions
Warning!
#
The seal is not allowed to press on the process isolating diaphragm as this could affect the
measurement result.
Note!
!
• Due to the orientation of the Deltabar S, there may be a shift in the measured value, i.e. when
the container is empty, the measured value does not display zero. You can correct this zero
point shift either via the "zero" key on the electronic insert, or on the outside of the device or
via the onsite display. See Page 15, Section 5.2.1 "Position of operating elements", Page 16,
Section 5.2.2 "Function of the operating elements – onsite display not connected" and Page
25, Section 6.3 "Position adjustment".
• For FMD77 and FMD78, please refer to Section 3.3 "Installation instructions for devices with
diaphragm seals (FMD78)", Page 7.
• The FMD77 must only be insulated up to a certain height.
4 Endress+Hauser
Deltabar S FOUNDATION Fieldbus Installation
• General recommendations for routing the impulse piping can be found in DIN 19210
"Methods for measurement of fluid flow; differential piping for flow measurement devices" or
the corresponding national or international standards.
• Using a three-valve or five-valve manifold allows for easy commissioning, installation and
maintenance without interrupting the process.
• When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is
used, e.g. by using pipe heat tracing.
• Do not clean or touch diaphragm seals with hard or pointed objects.
• Install the impulse piping with a monotonic gradient of at least 10%.
• To ensure optimal readability of the onsite display, it is possible to rotate the housing up to
380°.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
3.2 Measuring arrangement
3.2.1 Pressure measurement
• The PMD70, PMD75 and FMD78 are best suited for differential pressure measurement.
• Measuring arrangement for gases: Mount device above the measuring point.
• Measuring arrangement for liquids and steams: Mount device below tapping point.
• For differential pressure measurement in vapor, mount the condensate traps at the same level
as the same the tapping point and at the same distance from Deltabar S.
3.2.2 Level measurement
• All Deltabar S devices are best suited for level measurement in closed tanks.
• PMD70, PMD75, FMD76 and FMD77 are suitable to level measurement in open tanks.
Measuring arrangement level measurement in closed tanks and closed tanks with
superimposed vapor
• PMD70, PMD75: Mount device below the lower measuring connection. Always connect the
negative side above the maximum level via an impulse piping.
• FMD76, FMD77: Mount device direct on the tank. Always connect the negative side above
the maximum level via an impulse piping.
• FMD78 ä 7, Section 3.3 and Section 3.4.
• In the case of level measurement in closed tanks with superimposed vapor, a condensate trap
ensures pressure which remains constant on the minus side.
Measuring arrangement level measurement in open tanks
• PMD70, PMD75: Mount device below the lower measuring connection. The negative side is
open to atmosphere pressure.
• FMD76, FMD77: Mount device direct on the tank. The negative side is open to atmosphere
pressure.
3.2.3 Flow measurement
• The PMD70 and PMD75 are best suited for flow measurement.
• Measuring arrangement for gases: Mount device above the measuring point.

Deltabar S FOUNDATION Fieldbus Installation
3.3 Installation instructions for devices with diaphragm seals (FMD78)
Note!
!
• The diaphragm seal, together with the pressure transmitter, forms a closed, calibrated system,
which is filled through openings in the diaphragm seal and in the measurement system of the
pressure transmitter. These openings are sealed and must not be opened.
• Do not remove the protection of the process isolating diaphragm until shortly before
installation.
• When using a mounting bracket, sufficient strain relief must be ensured for the capillaries in
order to prevent the capillary bending down (bending radius 100 mm).
• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause zero
point shift. You can correct this zero point shift either via the "zero" key on the electronic
insert, or on the outside of the device or via the onsite display. See Page 15, Section 5.2.1
"Position of operating elements", Page 16, Section 5.2.2 "Function of the operating elements
– onsite display not connected" and Page 25, Section 6.3 "Position adjustment".
• Please note the application limits of the diaphragm seal filling oil as detailed in the Technical
Information for Deltabar S TI00382P, Section "Planning instructions for diaphragm seal
systems" or at "www.endress.com/applicator".
In order to obtain more precise measurement results and to avoid a defect in the device, mount
the capillaries as follows:
• vibration-free (in order to avoid additional pressure fluctuations)
• not in the vicinity of heating or cooling lines
• insulate if the ambient temperature is below ore above the reference temperature
• with a bending radius of 100 mm.
• The ambient temperature and length of both capillaries should be the same when using
two-sided diaphragm seal systems.
• Two diaphragm seals which are the same (e.g. with regard to diameter, material, etc.) should
always be used for the negative and positive side (standard delivery).

3.3.1 Vacuum application (FMD78)
For applications under vacuum, Endress+Hauser recommends mounting the pressure
transmitter underneath the lower diaphragm seal. A vacuum load of the diaphragm seal caused
by the presence of filling oil in the capillaries is hereby prevented.
When the pressure transmitter is mounted above the lower diaphragm seal, the maximum
height difference H1 in accordance with the illustration below on the left must not be exceeded.
The maximum height difference is dependent on the density of the filling oil and the smallest
ever pressure that is permitted to occur at the diaphragm seal on the positive side (empty
container), see illustration below, on the right.
