3.1 Installation position
!
Note!
• Due to the orientation of the Deltabar M, there may be a shift in the measured value, i.e. when
the container is empty, the measured value does not display zero. You may correct this zero
point shift by a position adjustment in one of the following ways:
– via the operation keys on the electronics module ( ä 13, "Function of the operating
elements")
– via the operating menu ( ä 28, "Position zero adjustment")
• 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.
• Install the impulse piping with a monotonic gradient of at least 10%.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls (see Operating
Instructions BA00383P).
3.1.1 Installation position for flow measurement
!
Note!
For more information about differential pressure flow measurement refer to following
documents:
• Differential pressure flow measurements with orifices: Technical Information TI00422P
• Differential pressure flow measurement with Pitot tubes: Technical Information TI00425P
Flow measurement in gases
• Mount the Deltabar M above the measuring point so that the condensate which may be
present, can run off into the process piping.
Flow measurement in steam
• Mount the Deltabar M below the measuring point.
• Mount the condensate traps at the same level as the tapping points and at the same distance
to the Deltabar M.
• Prior to commissioning, fill the impulse piping to the height of the condensate traps.
Flow measurement in liquids
• Mount the Deltabar M below the measuring point so that the impulse piping is always filled
with liquid and gas bubbles can run back into the process piping.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.

Endress+Hauser 7
3.1.2 Installation position for level measurement
Level measurement in an open container
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is
always filled with liquid.
• The low-pressure is open to atmospheric pressure.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
Level measurement in a closed container
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is
always filled with liquid.
• Always connect the low-pressure above the maximum level.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
Level measurement in a closed container with superimposed steam
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is
always filled with liquid.
• Always connect the low-pressure above the maximum level.
• A condensate trap ensures constant pressure on the low-pressure.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
3.1.3 Installation position for differential pressure measurement
Differential pressure measurement in gases and steam
• Mount the Deltabar M above the measuring point so that the condensate which may be
present, can run off into the process piping.
Differential pressure measurement in liquids

Note!
• When using the measuring device in hazardous areas, installation must comply with the
corresponding national standards and regulations and the Safety Instructions or Installation or
Control Drawings.
• All explosion protection data are given in separate documentation which is available upon
request. The Ex documentation is supplied as standard with all devices approved for use in
explosion hazardous areas.
4.2.2 Current consumption
11 mA ±1 mA, switch-on current corresponds to IEC 61158-2, Clause 21.

• Use a twisted, shielded two-wire cable, preferably cable type A.
• Terminals for wire cross-sections 0.5 to 2.5 mm
2
(20 to 14 AWG)
• Cable outer diameter: 5 to 9 mm (0.2 to 0.35 in) depends on the used cable gland (see
technical information)
!
Note!
For further information on the cable specifications, see Operating Instructions BA00034S

5.2 Operation with an operating menu
5.2.1 Operation concept
The operation concept makes a distinction between the following user roles:
User role Meaning
Operator Operators are responsible for the devices during normal "operation". This is usually limited to reading process
values either directly at the device or in a control room. If the work with the devices extends beyond value
read-off tasks, the tasks involve simple, application-specific functions that are used in operation. Should an error
occur, these users simple forward the information on the errors but do not intervene themselves.
Service
engineer/
technician
Service engineers usually work with the devices in the phases following device commissioning.
They are primarily involved in maintenance and troubleshooting activities for which simple settings have to be
made at the device.
Technicians work with the devices over the entire life cycle of the product.
Thus, commissioning and advanced settings and configurations are some of the tasks they have to carry out.
Deltabar M PROFIBUS PA Operation
Endress+Hauser 15
5.2.2 Structure of the operating menu
Expert Experts work with the devices over the entire product life cycle, but their device requirements are often
extremely high. Individual parameters/functions from the overall functionality of the devices are required for this
purpose time and again.
In addition to technical, process-oriented tasks, experts can also perform administrative tasks (e.g. user
administration).
"Experts" can avail of the entire parameter set.
User role Meaning
User role Submenu Meaning/use
Operator Language Only consists of the "Language" parameter (000) where the operating language for the device is
specified.
The language can always be changed even if the device is locked.
Operator Display/operat. Contains parameters that are needed to configure the measured value display (selecting the
values displayed, display format, etc.).
With this submenu, users can change the measured value display without affecting the actual
measurement.
Service
engineer/
technician
Setup Contains all the parameters that are needed to commission measuring operations. This submenu
has the following structure:
• Standard setup parameters
A wide range of parameters, which can be used to configure a typical application, is available
at the start. The measuring mode selected determines which parameters are available.
After making settings for all these parameters, the measuring operation should be completely
configured in the majority of cases.
• "Extended setup" submenu
The "Extended setup" submenu contains additional parameters for more in-depth
configuration of the measurement operation to convert the measured value and to scale the
output signal.
This menu is split into additional submenus depending on the measuring mode selected.
Service
engineer/
technician
Diagnosis Contains all the parameters that are needed to detect and analyze operating errors. This
submenu has the following structure:
• Diagnostic list
Contains up to 10 error messages currently pending.
• Event logbook
Contains the last 10 error messages (no longer pending).
• Instrument info
Contains information on the device identification.
• Measured values
Contains all the current measured values
• Simulation
Is used to simulate pressure, level, flow and alarm/warning.
• Factory reset
