to a reference temperature of 20°C (68°F) or 100°F (38 °C) for ANSI flanges.
• The pressure values permitted at higher temperatures can be found in the following
standards:– EN 1092-1: 2001 Tab. 18 1)– ASME B 16.5a – 1998 Tab. 2-2.2 F316
– ASME B 16.5a – 1998 Tab. 2.3.8 N10276– JIS B 2220
• The test pressure corresponds to the over pressure limit (OPL) of the device = MWP x 1.5
2).
• The Pressure Equipment Directive (EC Directive 97/23/EC) uses the abbreviation "PS". The
abbreviation "PS" corresponds to the MWP (maximum working pressure) of the measuring
device.
1)2)8With regard to their stability-temperature property, the materials 1.4435 and 1.4404 are grouped together
under 13EO in EN 1092-1 Tab. 18. The chemical composition of the two materials can be identical.
The equation does not apply for PMP51 and PMP55 with a 40 bar (600 psi) or a 100 bar (1500 psi) measuring

Installation instructions for devices without diaphragm seals –PMP51, PMC51

NOTICE

Damage to the device!
If a heated Cerabar M is cooled during the cleaning process (e.g. by cold water), a vacuum
develops for a short time, whereby moisture can penetrate the sensor through the pressurecompensation (1).
‣ If this is the case, mount the Cerabar M with the pressure compensation (1) pointing
downwards.

‣ A diaphragm seal and the pressure transmitter together form a closed, oil-filledcalibrated system. The fill fluid hole is sealed and may not be opened.
‣ When using a mounting bracket, sufficient strain relief must be ensured for thecapillaries in order to prevent the capillary bending down (bending radius 100(3.94 in)).
‣ Please observe the application limits of the diaphragm seal filling oil as detailed in theTechnical Information for Cerabar M TI00436P, "Planning instructions for diaphragm
seal systems" section.
NOTICE

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 or above the reference temperature‣ With a bending radius of  100 mm (3.94 in).
‣ Do not use the capillaries as a carrying aid for the diaphragm seals!

Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressuretransmitter below the diaphragm seal. This prevents vacuum loading of the diaphragm sealcaused by the presence of fill fluid in the capillary.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustrations below must not be exceeded.

H1

A0023994

Fig. 9:Installation above the lower diaphragm seal

The maximum height difference depends on the density of the filling oil and the smallest
ever pressure that is permitted to occur at the diaphragm seal (empty vessel), see illustration

Mounting with temperature isolator
Endress+Hauser recommends the use of temperature isolators in the event of constantextreme medium temperatures which lead to the maximum permissible electronics
temperature of +85 °C (+185°F) being exceeded.
Depending on the filling oil used, diaphragm seal systems with temperature isolators can beused for maximum temperatures of up to 400 °C (+752 °F). For the temperatureapplication limits, see technical Information, "Diaphragm seal filling oils" section.
To minimize the influence of rising heat, Endress+Hauser recommends the device bemounted horizontally or with the housing pointing downwards. The additional installation
height also brings about a maximum zero point shift of 21 mbar (0.315 psi) due to thehydrostatic column in the temperature isolator. You can correct this zero point shift at thedevice.
The temperature restrictions are lowest with an insulation height of 30 mm (1.18 inch).
Full insulation exhibits virtually the same behavior as no insulation!
The temperature limits with an insulation height of 30 mm (1.18 inch) are illustrated in thefollowing graphic.

Information on filling
The diaphragm seal must be filled as soon as it has been welded on.
• After welded into the process connection, the sensor assembly must be properly filled witha filling oil and sealed gas-tight with a sealing ball and lock screw.
Once the diaphragm seal has been filled, at the zero point the device display should notexceed 10% of the full scale value of the cell measuring range. The internal pressure of thediaphragm seal must be corrected accordingly.
• Adjustment / calibration:– The device is operational once it has been fully assembled.
– Perform a reset. The device must then be calibrated to the process measuring range as
described in the Operating Instructions.

Installation position• 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 47, "Function of the operating
elements")– via the operating menu ( ä 64, "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 andmaintenance without interrupting the process.
• When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection isused, 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 ( ä 29, "Walland pipe-mounting (option)").

Operation with an operating menu

6.3.1

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 withthe devices extends beyond value read-off tasks, the tasks involve simple, applicationspecific 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.

ExpertExperts 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.

Structure of the operating menu

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, display
contrast, 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 atypical 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 "Setup" submenu contains additional parameters for more indepth configuration of the measurement operation to convert themeasured value and to scale the output signal.
This menu is split into additional submenus depending on themeasuring mode selected.

Contains up to 10 error messages currently pending.
• Event logbook
Contains the last 10 error messages (no longer pending).
• Instrument info

nor integration into a distributed control system.
• Measurement
Contains all the parameters for configuring the measurement.
• OutputContains all the parameters for configuring the current output.
• Communication
Contains all the parameters for configuring the HART interface.

8.5.6"In height" level selection
Calibration without reference pressure (dry calibration)

Example:In this example, the volume in a tank should be measured in liters. The maximum volume of1000 liters (264 US gal) corresponds to a level of 4.5 m (15 ft). The minimum volume of 0liters corresponds to a level of 0.5 m (1.6 ft) since the device is mounted below the start ofthe level measuring range.
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.

• The values for "Empty calib./Full calib.", "Empty height/Full height" and" Set LRV/Set URV"
must be at least 1% apart. The value will be rejected, and a warning message displayed, 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 for the measuring
device to be able to measure correctly.
• Due to the orientation of the device, there may be pressure shifts in the measured value,i.e. when the container is empty or partly filled, the measured value is not zero. For
information on how to perform position adjustment, see  ä 64, "Position zeroadjustment".

Flow measurement (Deltabar M)

8.10.1

Information on flow measurement

In the "Flow" measuring mode, the device determines a volume or mass flow value from thedifferential pressure measured. The differential pressure is generated by means of primaryelements such as pitot tubes or orifice plates and depends on the volume or mass flow. Fourflow types are available: volume flow, norm volume flow (European norm conditions),
standard volume flow (American standard conditions), mass flow and flow in %.
In addition, the Deltabar M software is equipped with two totalizers as standard. The
totalizers add up the volume or the mass flow. The counting function and the unit can be set
separately for both totalizers. The first totalizer (totalizer 1) can be reset to zero at any time
while the second (totalizer 2) totalises the flow from commissioning onwards and cannot be
reset.

The totalizers are not available for the "Flow in %" flow type.

Information on level measurement

You have a choice of two methods for calculating the level: "In pressure" and "In height". The
table in the "Overview of level measurement" section that follows provides you with an
overview of these two measuring tasks.
• The limit values are not checked, i.e. the values entered must be appropriate for the sensor
and the measuring task for the device to be able to measure correctly.
• Customer-specific units are not possible.
• The values entered for "Empty calib./Full calib.", "Empty pressure/Full pressure", "Empty
height/Full height" and "Set LRV/Set URV" must be at least 1% apart. The value will berejected, and a message output, if the values are too close together.

Cleaning instructions

Endress+Hauser offer flushing rings as accessories to clean process isolating diaphragms
without taking the transmitters out of the process.
For further information please contact your local Endress+Hauser Sales Center.

9.1.1

Cerabar M PMP55

We recommend you perform CIP (cleaning in place (hot water)) before SIP (sterilization inplace (steam)) for pipe diaphragm seals. A frequent use of sterilization in place (SIP) will
increase the stress on the process isolating diaphragm. Under unfavorable circumstances in
the long term view we cannot exclude that a frequent temperature change could lead to amaterial fatigue of the process isolating diaphragm and possibly to a leakage.

9.2

Exterior cleaning

Please note the following points when cleaning the device:• The cleaning agents used should not corrode the surface and the seals.
• Mechanical damage to the process isolating diaphragm, e.g. due to pointed objects, must
be avoided.
• Observe the degree of protection of the device. See the nameplate if necessary ( ä 8 ff).

Messages

The following table lists the messages that can occur. The Diagnostic code parameter shows
the message with the highest priority. The device has four different status information codes
according to NAMUR NE107:• F = failure• M (warning) = maintenance required• C (warning) = function check• S (warning) = out of specification (deviations from the permitted ambient or process
conditions determined by the device with the self-monitoring function, or errors in thedevice itself indicate that the measuring uncertainty is greater than what would be
expected under normal operating conditions).
