4.5.1Installation instructions for devices without diaphragm seals –
PMP51, PMC51
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 pressure
compensation (1).
‣ If this is the case, mount the Cerabar M with the pressure compensation (1) pointing
downwards.
®
• Keep the pressure compensation and GORE-TEX
• Cerabar M transmitters without diaphragm seals are mounted as per the norms for a
manometer (DIN EN 837-2). We recommend the use of shutoff devices and siphons. The
orientation depends on the measuring application.
• Do not clean or touch process isolating diaphragms with hard or pointed objects.
• The device must be installed as follows in order to comply with the cleanability
requirements of the ASME-BPE (Part SD Cleanability):

NOTICE
NOTICE
4.5.2Installation instructions for devices with diaphragm seals –
PMP55
• Cerabar M devices with diaphragm seals are screwed in, flanged or clamped, depending on
the type of diaphragm seal.
• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause
zero point shift. The zero point shift can be corrected.
• Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or
pointed objects.
• Do not remove process isolating diaphragm protection until shortly before installation.
Improper handling!
Damage to the device!
‣ A diaphragm seal and the pressure transmitter together form a closed, oil-filled
calibrated system. The fill fluid hole is sealed and may not be opened.
‣ 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
(3.94 in)).
‣ Please observe the application limits of the diaphragm seal filling oil as detailed in the
Technical Information for Cerabar M TI00436P, "Planning instructions for diaphragm
seal systems" section.
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 pressure
transmitter below the diaphragm seal. This prevents vacuum loading of the diaphragm seal
caused 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.
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 constant
extreme 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 be
used for maximum temperatures of up to 400 °C (+752 °F). For the temperature
application limits, see technical Information, "Diaphragm seal filling oils" section.
To minimize the influence of rising heat, Endress+Hauser recommends the device be
mounted 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 the
hydrostatic column in the temperature isolator. You can correct this zero point shift at the
device.
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 the
following graphic.

4.6Installing Deltabar M
Incorrect handling!
Damage of the device!
‣ Disassembly of the screws with item number (1) is not permissible under any
circumstances and will result in loss of warranty.
4.6.1Installation 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 73, "Pos. zero adjust")
• 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 ( ä 29, "Wall
and pipe-mounting (option)").

4.7Installing Deltapilot M
• Due to the orientation of the Deltapilot M, there may be a shift in the zero point, i.e. when
the container is empty or partially full, the measured value does not display zero. You can
correct this zero point shift ä 47, Section "Function of the operating elements" or
ä 73, Section 8.3 "Pos. zero adjust".
• The local display can be rotated in 90° stages.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä 21, Section 4.5.5 "Wall and pipe mounting (optional)".
4.7.1General installation instructions
• Do not clean or touch process isolating diaphragms with hard or pointed objects.
• The process isolating diaphragm in the rod and cable version is protected against
mechanical damage by a plastic cap.
• If a heated Deltapilot 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
pressure compensation (1). If this is the case, mount the Deltapilot M with the pressure
compensation (1) pointing downwards.
• Keep the pressure compensation and GORE-TEX
®
filter (1) free from contamination.
• The device must be installed as follows in order to comply with the cleanability
requirements of the ASME-BPE (Part SD Cleanibility).:

• Always install the device below the lowest measuring point.
• Do not install the device at the following positions:
– in the filling curtain
– in the tank outflow
– in the suction area of a pump
– or at a point in the tank that can be affected by pressure pulses from the agitator
• The calibration and functional test can be carried out more easily if you mount the device
downstream of a shutoff device.
• Deltapilot M must be included in the insulation for media that can harden when cold.
Pressure measurement in gases
• Mount Deltapilot M with shutoff device above the tapping point so that any condensate
can flow into the process.
Pressure measurement in steams
• Mount Deltapilot M with siphon above the tapping point.
• Fill the siphon with liquid before commissioning.
The siphon reduces the temperature to almost the ambient temperature.

• When mounting rod and cable versions, make sure that the probe head is located at a point
as free as possible from flow. To protect the probe from impact resulting from lateral
movement, mount the probe in a guide tube (preferably made of plastic) or secure it with
a clamping fixture.
• In the case of devices for hazardous areas, comply strictly with the safety instructions
when the housing cover is open.
• The length of the extension cable or the probe rod is based on the planned level zero point.
The height of the protective cap must be taken into consideration when designing the

OperatorOperators are responsible for the devices during normal "operation". This is usually limited
Service engineer/

ExpertExperts work with the devices over the entire product life cycle, but their device
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, 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 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.
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).

SetupContains 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 indepth 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

6.3.3Operation with a device display (optional)
A 4-line liquid crystal display (LCD) is used for display and operation. The onsite display
shows measured values, dialog texts, fault messages and notice messages.
For easy operation the display can be taken out of the housing (see figure steps 1 to 3). It is
connected to the device through a 90 mm (3.54 in) cable.
The display of the device can be turned in 90° stages (see figure steps 4 to 6).
Depending on the orientation of the device, this makes it easy to operate the device and read
the measured values.

FieldCare is an Endress+Hauser asset management tool based on FDT technology. With
FieldCare, you can configure all Endress+Hauser devices as well as devices from other
manufacturers that support the FDT standard. Hard- and software requirements can be
found on the Internet: www.endress.com → Search for: FieldCare → FieldCare → Technical
data.
FieldCare supports the following functions:
• Configuration of transmitters in online/offline mode
• Loading and saving device data (upload/download): see parameter "Download select"
ä 119 in operating menu or via Resource block ä 173.
• Documentation of the measuring point
• Offline parametrization of transmitters
• In "Level expert" measuring mode, the configuration data which were generated by FDT
upload cannot be saved back again (FDT download); they are used solely to document the
configuration.
• Further information on FieldCare can be found on the Internet (http://www.endress.com,
Download Search for: FieldCare).
• As not all internal device dependencies can be mapped in offline operation, the
consistency of the parameters must be checked before the parameters are transmitted to
the device.
• All the function blocks are set to the OOS mode following a download. The DIP switches
must be set to the as-delivered state for this purpose (see Figure ä 46).

6.4.2Number of devices
• Endress+Hauser devices meet the requirements specified by the FISCO model.
• Due to the low current consumption, the following can be operated at one bus segment
when
installation is performed according to FISCO:
– Up to 6 devices for EEx ia, CSA and FM IS applications
– Up to 22 devices in all other applications, e.g. in non hazardous areas, EEx nA etc.
The maximum number of measuring devices at one bus segment is defined by their current
consumption, the performance of the bus coupler, and the required bus length.
6.4.3Operation
You can obtain special configuration and operating programs from various manufacturers
for the configuration, such as the FieldCare operating program from Endress+Hauser
ä 53, Section 6.3.4 "Operation via FieldCare". These configuration programs make it
possible to configure FF functions and all the device-specific parameters. The predefined
function blocks allow uniform access to network and device data.
6.4.4Network configuration
You require the following to configure a device and integrate it into an FF network:
• An FF configuration program
• The Cff file (Common File Format: *.cff)
• The device description (DD)
(Device Description format 4 : *sym, *ffo or
Device Description format 5 : *sy5, *ff5)
Pre-defined standard DDs, which can be obtained from FOUNDATION Fieldbus, are available
for the basic functions of measuring devices. You require the device-specific DD to be able to
access all the functions.
The files for the devices can be acquired as follows:
• Internet Endress+Hauser: http://www.endress.com Search for FOUNDATION Fieldbus
• Internet FOUNDATION Fieldbus: http://www.fieldbus.org
The device is integrated into the FF network as follows:
• Start the FF configuration program.
• Download the Cff and device description files (*.ffo, *.sym (for format 4) *ff5, *sy5 (for
format 5) to the system.
• Configure the interface, see Note.
• Configure the device for the measuring task and for the FF system.
• For more in-depth information on integrating the device into the FF system, see the
description for the configuration software used.
• When integrating the field devices into the FF system, make sure you are using the right
files. You can read out the required version by means of the Device Revision/DEV_REV and
DD Revision/DD_REV parameters in the Resource Block.

6.4.5Device identification and addressing
FOUNDATION Fieldbus identifies the device using its ID code and automatically assigns it a
suitable field address. The identity code cannot be changed.
The device appears in the network display once you have started the FF configuration
program and integrated the device into the network. The blocks available are displayed
under the device name.
If the device description has not yet been loaded, the blocks report "Unknown" or "(UNK)".
The devices report as follows (typical display in a configuration program after the connection
has been established):
With FOUNDATION Fieldbus, all the device parameters are categorized according to their
functional properties and task and are generally assigned to three different blocks.
A FOUNDATION Fieldbus device has the following block types:
• A Resource Block (device block):
This block contains all the device-specific features of the device.
• One or more Transducer Blocks
A Transducer Block contains all the measuring and device-specific parameters of the
device. The measuring principles, such as pressure or totalizers, are mapped in the
Transducer Blocks.
• One or more function blocks:
Function blocks contain the automation functions of the device. A distinction is made
between different function blocks such as the Analog Input Block or PID Block. Each of
these function blocks is used to execute different application functions.
The function blocks can be connected by means of an FF configuration program, depending
on the automation task. The device thus takes on simple control functions, thereby relieving
the workload on the higher-order process control system.
The device has the following blocks:
• Resource Block (device block)
• 3 Transducer Blocks for all devices
– Pressure Transducer Block
This Block returns the output variables Primary Value/PRIMARY_VALUE and
Secondary Value/SECONDARY_VALUE. It contains all the parameters to configure the
measuring device for the measuring task such as measuring mode selection,
linearization function and unit selection.
– Display Transducer Block
This Block does not return any output variables. It contains all the parameters for
configuring the onsite display, such as Language/DISPLAY_LANGUAGE.
– Diagnostic Transducer Block
This Block does not return any output variables. It contains the simulation function for
the Pressure Transducer Block, parameters to configure the alarm response.
• In addition, 1 Transducer Block for Deltabar M
–DP_FLOW Block
This Block supplies the output variable Totalizer 1/TOTALIZER_1 and Totalizer 2/
TOTALIZER_2. It contains all the parameters required for configuring these totalizers.
• Function blocks in all devices
– 2 Analog Input Blocks (AI) (permanent block - cannot be deleted)
– Discrete Output Block (DO) (permanent block - cannot be deleted)
– Discrete Input Block (DI) (permanent block - cannot be deleted)
– Input Selector Block (ISB) (permanent block - cannot be deleted)
– PID Block (PID) (non-permanent block - can be deleted)
– Arithmetic Block (ARB) (non-permanent block - can be deleted)
– Signal Characterizer Block (SCB) (non-permanent block - can be deleted)
– Integrator Block (IT) (non-permanent block - can be deleted)
In addition to the pre-instantiated blocks already mentioned, the following blocks can also
be instantiated:
With Deltabar M:
• 3 Analog Input Blocks (AI)
• 4 Discrete Input Blocks (DI)
• 1 Discrete Output Block (DO)
• 2 Input Selector Block (ISB)
•2 PID Blocks (PID)
• 2 Arithmetic Blocks (ARTH)
• 2 Signal Characterizer Blocks (SCB)
• 2 Integrator Blocks (IT)

The Pressure Transducer Block supplies the primary value depending on the measuring
mode, and a secondary value
• for Cerabar/Deltapilot, secondary value = sensor temperature.
• for Deltabar, secondary value = Measured pressure.
By means of the Channel/CHANNEL parameter, the measured values (primary value,
secondary value, etc.) are transferred to an Analog Input Block from the Transducer Block,
see also the following section).
The Discrete Output, PID, Arithmetic, Signal Characterizer and Input Selector Block are not

• 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.
• There is no unit conversion.
• The values entered for "Empty calib. (028)/Full calib. (031)", "Empty pressure (029)/Full
pressure (032)", "Empty height (030)/Full height (033)" must be at least 1 % apart. The
value will be rejected, and a warning message displayed, if the values are too close
together.
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.

Calibration without reference pressure (dry calibration)
Example:
In this example, the volume in a tank should be measured in liters. The maximum volume of
1000 liters (264 gal) corresponds to a pressure of 450 mbar (6.53 psi). The minimum
volume of 0 liters corresponds to a pressure of 50 mbar (0.72 psi) since the device is
mounted below the start of the level measuring range.
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.
• The values entered for "Empty calib. (028)/Full calib. (031)", "Empty pressure (029)/Full
pressure (032)" must be at least 1% apart. The value will be rejected, and a warning

8.8Flow measurement (Deltabar M)
8.8.1Information on flow measurement
In the "Flow" measuring mode, the device determines a volume or mass flow value from the
differential pressure measured. The differential pressure is generated by means of primary
elements such as pitot tubes or orifice plates and depends on the volume or mass flow. Four
flow 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) totalizes the flow from commissioning onwards and cannot be
reset.
The totalizers are not available for the "Flow in %" flow type.

8.9.2"In pressure" level selection
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 due to the filling height and the density.
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• The tank can be filled and emptied.
The values entered for "Empty calib. (028)/Full calib. (031)" and the pressures present at the
device 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 so that the
measuring device can measure correctly.
