The measuring system is used to measure the volume flow of saturated steam, overheated steam,
gases and liquids. If the process pressure and process temperature are constant, the measuring
device can also output the flow as the calculated mass flow or corrected volume flow.
Resulting from incorrect use or from use other than that designated, the operational safety of the
measuring devices can be suspended. The manufacturer accepts no liability for damages being
produced from this.
1.2Installation, commissioning and operation
Note the following points:
• Installation, electrical installation, commissioning and maintenance of the device must be carried
out by trained, qualified specialists authorized to perform such work by the facility's owneroperator. The specialist must have read and understood these Operating Instructions and must
follow the instructions they contain.
• The device must be operated by persons authorized and trained by the facility's owner-operator.
Strict compliance with the instructions in these Operating Instructions is mandatory.
• Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts wetted
by special fluids, including fluids used for cleaning. However, small changes in temperature,
concentration or the degree of contamination in the process can result in changes of the chemical
resistance properties. Therefore, Endress+Hauser can not guarantee or accept liability for the
chemical resistance properties of the fluid wetted materials in a specific application. The user is
responsible for the choice of fluid wetted materials in regards to their in-process resistance to
corrosion.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams.
• Invariably, local regulations governing the operation, maintenance and repair of electrical devices
apply. Special instructions relating to the device can be found in the relevant sections of the
documentation.
1.3Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of these Operating Instructions. Strict compliance with
the installation instructions and ratings as listed in this supplementary documentation is
mandatory. The symbol on the front of the Ex documentation indicates the approval and the
certification center ( 0 Europe, 2 USA, 1 Canada).
• The measuring system complies with the general safety requirements in accordance with
EN 61010-1 and the EMC requirements of IEC/EN 61326 and NAMUR Recommendations NE
21, NE 43 and NE 53.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Endress+Hauser distributor will supply you with current information and updates to these
Operating Instructions.

1.4Return
The following procedures must be carried out before a flowmeter requiring repair or calibration, for
example, is returned to Endress+Hauser:
• Always enclose a fully completed "Declaration of Contamination" form with the device. Only then
can Endress+Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per European
Directive 91/155/EEC.
• Remove all fluid residues. Pay special attention to the grooves for seals and crevices which could
contain fluid residues.
This is particularly important if the fluid is hazardous to health, e.g. flammable, toxic, caustic,
carcinogenic, etc.

3.1Incoming acceptance, transport, storage
3.1.1Incoming acceptance
On receipt of the goods, check the following points:
• Check the packaging and the contents for damage.
• Check the shipment, make sure nothing is missing and that the scope of supply matches your
order.
3.1.2Transport
Please note the following when unpacking or transporting to the measuring point:
• The devices must be transported in the container supplied.
• Devices with nominal diameter DN 40 to 300 (1½ to 12") may not be lifted at the transmitter
housing or at the connection housing of the remote version when transporting (see Fig. 4). Use
carrier slings when transporting and put the slings around both process connections. Avoid chains
as these could damage the housing.
#
Warning!
Risk of injury if the measuring device slips.
The center of gravity of the entire measuring device might be higher than the points around which
the slings are slung. Therefore, when transporting, make sure that the device does not
unintentionally turn or slip.
A0001871
Fig. 4:Transportation instructions for sensors with DN 40 to 300 (1½ to 12")
3.1.3Storage
Note the following points:
• Pack the measuring device in such a way as to protect it reliably against impact for storage (and
transportation). The original packaging provides optimum protection.
• The permissible storage temperature is:
– Standard: –40 to +80 °C (–40 to +176 °F)
– ATEX II 1/2 GD version/dust ignition-proof: –20 to +55 °C (–4 to +131 °F)
• When in storage, the device should not be exposed to direct sunlight in order to avoid
impermissibly high surface temperatures.

3.2Installation conditions
Note the following points:
• The measuring device requires a fully developed flow profile as a prerequisite for correct volume
flow measurement. The inlet and outlet runs must be taken into account (see Page 14).
• The maximum permitted ambient temperatures (see Page 83) and fluid temperatures (see
Page 84) must be observed.
• Pay particular attention to the notes on orientation and piping insulation (see Page 12).
• Verify that the correct nominal diameter and pipe standard (DIN/JIS/ANSI) were taken into
account when ordering since the calibration of the device and the achievable accuracy depend on
these factors. If the mating pipe and the device have different nominal diameters/pipe standards,
an inlet correction can be made via the device software by entering the actual pipe diameter (see
MATING PIPE DIAMETER function on Page 115).
• The correct operation of the measuring system is not influenced by plant vibrations up to 1 g,
10 to 500 Hz.
• For mechanical reasons, and in order to protect the piping, it is advisable to support heavy sensors.
For weight information, please refer to Technical Information TI070D/06/en.
3.2.1Dimensions
The dimensions and lengths of the sensor and transmitter can be found in the Technical Information
TI070D/06/en.
3.2.2Installation location
We recommend you observe the following dimensions to guarantee problem-free access to the
device for service purposes:
• Minimum spacing (A) in all directions = 100 mm (3.94 inch)
• Necessary cable length (L): L + 150 mm (L + 5.91 inch).

3.2.3Orientation
The device can be installed basically in any orientation. Please consider the following, however
(Fig. 6):
• In the case of liquids, there should be upward flow in vertical pipes to avoid partial pipe filling (see
orientation A).
• The arrow on the meter body has to point in flow direction.
• In order to make sure that the maximum ambient temperature (see Page 83) is not exceeded, we
recommend the following orientations:
– In the case of hot fluids (e.g. steam or fluid temperature 200 °C/392 °F), select orientation
C or D.
– Orientations B and D are recommended for very cold fluids (e.g. liquid nitrogen).
Caution!
"
• If fluid temperature is 200 °C ( 392 °F), orientation B is not permitted for the wafer version
(Prowirl 72 W) with a nominal diameter of DN 100 (4") and DN 150 (6").
• In case of vertical orientation and downward flowing liquid, the piping has always to be
completely filled.
Fig. 6:Possible orientations of the device
High fluid temperature:
– horizontal piping: orientation C or D
– vertical piping: orientation A
Low fluid temperature:

3.2.4Heat insulation
Some fluids require suitable measures to avoid heat transfer at the sensor. A wide range of materials
can be used to provide the required insulation.
When insulating, please ensure that a sufficiently large area of the housing support is exposed. The
uncovered part serves as a radiator and protects the electronics from overheating (or undercooling).
The maximum insulation height permitted is illustrated in the Fig. 7. These apply equally to both
the compact version and the sensor in the remote version.
"

Perforated plate flow conditioner
A specially designed perforated plate flow conditioner, available from Endress+Hauser, can be
installed if it is not possible to observe the inlet runs required. The flow conditioner is fitted between
two piping flanges and centered with mounting bolts. Generally, this reduces the inlet run required
to 10 DN with complete accuracy.
A0001887
Fig. 10:Perforated plate flow conditioner
Calculation examples (SI units) for the pressure loss of flow conditioners:
The pressure loss for flow conditioners is calculated as follows:
p [mbar] = 0.0085 · [kg/m³] · v² [m/s]
• Example with steam
p = 10 bar abs
t = 240 °C = 4.39 kg/m³
v = 40 m/s
• Example with H
= 965 kg/m³
v = 2.5 m/s
p = 0.0085 · 965 · 2.5
O condensate (80°C)
2
= 51.3 mbar
p = 0.0085 · 4.39 · 40² = 59.7 mbar
3.2.6Vibrations
The correct operation of the measuring system is not influenced by plant vibrations up to 1 g, 10 to
500 Hz. Consequently, the sensors require no special measures for attachment.

3.3.1Mounting sensor
Caution!
"
Please note the following prior to mounting:
• Prior to installing the measuring device in the piping, remove all traces of transport packaging and
any protective covers from the sensor.
• Make sure that the internal diameters of seals are the same as, or greater than, those of the
measuring pipe and piping. Seals projecting into the flow current have a negative effect on the
vortex formation after the bluff body and cause inaccurate measurement.The gaskets provided
by Endress+Hauser for the wafer version have therefore an inner diameter with a bigger inner
diameter than the piping.
• Ensure that the arrow on the measuring pipe matches the direction of flow in the piping.
• Lengths:
– Prowirl W (wafer version): 65 mm (2.56 inch)
– Prowirl F (flanged version) See Technical Information TI070D/06/en.
Mounting Prowirl W
The centering rings supplied are used to mount and center the wafer-style devices.
A mounting kit consisting of tie rods, seals, nuts and washers can be ordered separately.

Warning!
When connecting Ex-certified devices, please refer to the notes and diagrams in the Ex-specific
supplement to these Operating Instructions. Please do not hesitate to contact your Endress+Hauser
representative if you have any questions.
4.1PROFIBUS PA cable specifications
Cable type
Twin-core cables are recommended for connecting the device to the fieldbus. Following IEC
61158-2 (MBP), four different cable types (A, B, C, D) can be used with the fieldbus, only two of
which (cable types A and B) are shielded.
• Cable types A or B are particularly preferable for new installations. Only these types have cable
shielding that guarantees adequate protection from electromagnetic interference and thus the
most reliable data transfer. In the case of multi-pair cables (type B), it is permissible to operate
multiple fieldbuses (with the same degree of protection) on one cable. No other circuits are
permissible in the same cable.
• Practical experience has shown that cable types C and D should not be used due to the lack of
shielding, since the freedom from interference generally does not meet the requirements
described in the standard.
The electrical data of the fieldbus cable have not been specified but determine important
characteristics of the design of the fieldbus, such as distances bridged, number of users,
electromagnetic compatibility, etc.

• Belden: 3076F
• Kerpen: CeL-PE/OSCR/PVC/FRLA FB-02YS(ST)YFL
20Endress + Hauser
Page 21
Proline Prowirl 72 PROFIBUS PA4 Wiring
Maximum overall cable length
The maximum network expansion depends on the type of protection and the cable specifications.
The overall cable length combines the length of the main cable and the length of all spurs (>1 m
(>3 ft)).
Note the following points:
• The maximum permissible overall cable length depends on the cable type used:
Type A1900 m6200 ft
Type B1200 m4000 ft
• If repeaters are used, the maximum permissible cable length is doubled.
A maximum of three repeaters are permitted between user and master.
Maximum spur length
The line between the distribution box and field device is described as a spur.
In the case of non-Ex applications, the max. length of a spur depends on the number of spurs (>1 m)
(>3 ft):
Number of spurs1 to 1213 to 1415 to 1819 to 2425 to 32
Max. length per spur
[m]120 90 60301
[ft]400 300 200 1003
Number of field devices
In systems that meet FISCO in the EEx ia type of protection, the line length is limited to
max. 1000 m (3280 ft). A maximum of 32 users per segment in non-Ex areas or a maximum of
10 users in an Ex-area (EEx ia IIC) is possible. The actual number of users must be determined
during project planning.
Bus termination
The start and end of each fieldbus segment are always to be terminated with a bus terminator. With
various junction boxes (non-Ex), the bus termination can be activated via a switch. If this is not the
case, a separate bus terminator must be installed.
Note the following points:
• In the case of a branched bus segment, the device furthest from the segment coupler represents
the end of the bus.
• If the fieldbus is extended with a repeater then the extension must also be terminated at both
ends.
Further information
General information and further notes regarding the wiring can be found in the BA034S/04: "Field
communication PROFIBUS DP/PA: Guidelines for planning and commissioning".

4.1.1Shielding and grounding
When planning the shielding and grounding for a fieldbus system, there are three important points
to consider:
• Electromagnetic compatibility (EMC)
• Explosion protection
• Safety of the personnel
To ensure the optimum electromagnetic compatibility of systems, it is important that the system
components and above all the cables, which connect the components, are shielded and that no
portion of the system is unshielded. Ideally, the cable shields will be connected to the field devices'
housings, which are usually metal. Since these are generally connected to the protective earth, the
shield of the bus cable is grounded many times. Make sure that the stripped and twisted lengths of
cable shield to the terminals are as short as possible.
This approach, which provides the best electromagnetic compatibility and personnel safety, can be
used without restriction in systems with good potential equalization.
In the case of systems without potential equalization, a power supply frequency (50 Hz) equalizing
current can flow between two grounding points which, in unfavorable cases, e.g. when it exceeds
the permissible shield current, may destroy the cable.
To suppress the low frequency equalizing currents on systems without potential equalization, it is
therefore recommended to connect the cable shield directly to the building ground (or protective
earth) at one end only and to use capacitive coupling to connect all other grounding points.
"
!
Caution!
The legal EMC requirements are met only when the cable shield is grounded at both ends!.

4.3Connecting the measuring unit
4.3.1Connecting the transmitter
!
"
Note!
• When connecting Ex-certified devices, please refer to the notes and diagrams in the Ex-specific
supplement to these Operating Instructions.
• The remote version must be grounded. In doing so, the sensor and transmitter must be connected
to the same potential equalization.
• The national regulations governing the installation of electrical equipment must be observed.
• When connecting the transmitter, use a connecting cable with a continuous service temperature
of at least –40 °C (–40 °F) to permitted max. ambient temperature plus 10 °C (plus 18 °F).
• A shielded cable must be used for the connection.
• The terminals for the PROFIBUS PA connection (terminal 1 = PA+, terminal 2 = PA –) have
integrated reverse polarity protection. This ensures correct signal transmission via the fieldbus
even if lines are confused.
• Cable cross-section: max. 2.5 mm²
• Observe the grounding concept.
Caution!
• Risk of damaging the PROFIBUS cable!
If the shielding of the cable is grounded at more than one point in systems without additional
potential equalization, power supply frequency equalization currents can occur that damage the
cable or the shielding. In such cases the shielding of the cable is to be grounded on only one side,
i.e. it must not be connected to the ground terminal of the housing. The shield that is not
connected should be insulated!
• We recommend that the PROFIBUS not be looped using conventional cable glands. If you later
replace even just one measuring device, the bus communication will have to be interrupted.

4.3.3Fieldbus connector
The connection technology of PROFIBUS PA allows measuring devices to be connected
to the fieldbus via uniform mechanical connections such as T-boxes, distribution modules, etc.
This connection technology using prefabricated distribution modules and plug-in connectors offers
substantial advantages over conventional wiring:
• Field devices can be removed, replaced or added at any time during normal operation.
Communication is not interrupted.
• Installation and maintenance are significantly easier.
• Existing cable infrastructures can be used and expanded instantly, e.g. when constructing new
star distributors using 4-channel or 8-channel distribution modules.
The device can therefore be supplied with the option of a ready-mounted fieldbus connector.
Fieldbus connectors for retrofitting can be ordered from Endress+Hauser as a spare part (see
Page 73).
Supply line/T-box shielding
Use cable glands with good EMC properties, if possible with all-round contact of the cable shielding
(Iris spring). This requires small differences in potential, poss. potential equalization.
• The PA cable shielding must be intact.
• The shielding connection must always be kept as short as possible.
Ideally, cable glands with Iris springs should be used for the shielding connection. The shielding is
positioned on the T-box housing by means of the Iris spring located inside the gland. The shielding
braid is located beneath the Iris spring. When the armored thread is tightened, the Iris spring is
pressed against the shielding, thereby creating a conductive connection between the shielding and
the metal housing.
A connection box or a plug-in connection is to be seen as part of the shielding (Faraday shield). This
applies, in particular, to remote boxes if these are connected to a PROFIBUS PA measuring device
by means of a pluggable cable. In such instances, a metallic connector must be used where the cable
shielding is positioned at the plug housing (e.g. prefabricated cables).

The measuring device meets all the requirements for IP 67 (NEMA 4X).
Caution!
"
Do not loosen the screws of the sensor housing, as otherwise the degree of protection guaranteed
by Endress+Hauser no longer applies.
Compliance with the following points is mandatory following installation in the field or servicing in
order to ensure that IP 67 (NEMA 4X) protection is maintained:
• The housing seals must be clean and undamaged when inserted into their grooves. The seals must
be dried, cleaned or replaced if necessary.
• The housing screws and screw caps must be firmly tightened.
• The cables used for connection must be of the specified outside diameter Page 81, cable
entries.
• The cable entries must be firmly tightened (point a Fig. 20).
• The cable must loop down before it enters the cable entry ("water trap") (point b Fig. 20).
This arrangement prevents moisture penetrating the entry.
The cable entries should not point upwards.
• Replace all unused cable entries with dummy plugs.
• Do not remove the grommet from the cable entry.

5.5.2Configuring the device address
Note the following points:
• In the case of a PROFIBUS PA device, the address must always be configured.
The valid device addresses are in the range from 1 to 126. In a PROFIBUS PA network, each
address can only be assigned once. If an address is not configured correctly, the device is not
recognized by the master.
The address 126 can be used for initial commissioning and for service purposes.
• All devices have the address 126 and software addressing on leaving the factory.
Procedure for configuring the device address ( Fig. 25 on Page 44):
1.Switch off power supply.
2.Unscrew the cover of the electronics compartment from the transmitter housing.
3.Remove the display module (a) from the retaining rails (b) and refit onto right retaining rail with
the left side (this secures the display module).
4.Fold up the plastic cover (c).
5.Fold up the cover (d) of the I/O board (COM module).

5.Configuring cyclic data traffic:
– All the relevant data are described in the "System integration" ( Page 48) section.
– We recommend that the "Coupling Documentation" be used for step-by-step configuration.
This can be obtained from Endress+Hauser Process Solutions for various automation systems
and programmable logic controllers.
– The files required for commissioning and network configuration can be obtained as described
on Page 48 ff.
6.3System integration
The device is ready for system integration once commissioning has been effected via the Class 2
master (Commuwin II). The PROFIBUS PA system requires a description of the device parameters,
e.g. output data, input data, data format, data volume and supported transmission rate so that it can
integrate the field devices into the bus system.
These data are contained in a Device Master File (GSD file) which is placed at the disposal of the
PROFIBUS PA master while the communication system is being commissioned.
Device bitmaps, which appear as icons in the network tree, can also be integrated. The Profile 3.0
Device Master File (GSD) allows field devices from various manufacturers to be exchanged without
having to reconfigure.
Generally, the Profile 3.0 distinguishes between three different versions of GSD (factory setting:
manufacturer-specific GSD):
!
Manufacturer-specific GSD: This GSD guarantees the unlimited functionality of the field device.
Device-specific process parameters and functions are therefore available.
Profile GSD: This GSD is different in terms of the number of Analog Input Blocks (AI) and the
measuring principles. If a system is configured with profile GSDs, it is possible to exchange devices
that are supplied by various manufacturers. It is, however, essential that the cyclic process values
follow the same sequence.
Example:
The Proline Prowirl 72 PROFIBUS PA supports the Profile PA139740.gsd (IEC 61158-2 (MBP)).
This GSD contains one Analog Input Block and one Totalizer Block. The following measured
variable is always assigned to the Analog Input Block: AI 1 = Volume flow. This guarantees that the
first measured variable agrees with the field devices of other manufacturers.
Profile GSD (multivariable) with the ID number 9760
: This GSD contains all function blocks
Hex
such as AI, DO, DI etc. This GSD is not supported by Prowirl 72.
Note!
• A decision should be made with respect to which GSD is to be used before configuration takes
place.
• The setting can be changed using a Class 2 master.
Prowirl 72 supports the following GSD files:

Proline Prowirl 72 PROFIBUS PA6 Commissioning
Each device receives an identification number from the Profibus User Organization (PNO). The
name of the Device Master File (GSD) is derived from this.
For Endress+Hauser, this ID No. starts with the manufacturer ID 15xx.
In order to ensure clarity and make assignment easier, the GSD names (with the exception of type
files) at Endress+Hauser are as follows:
EH3_15xxEH = Endress + Hauser
3 = Profile 3.0
_ = Standard identification
15xx = ID No.
EH3x15xxEH = Endress + Hauser
3 = Profile 3.0
x = Extended identification
15xx = ID No.
The GSD files for all Endress+Hauser devices can be acquired in the following manner:
• Internet (Endress+Hauser) http://www.endress.com (Products Process
Solutions PROFIBUS GSD files)
• Internet (PNO) http://www.profibus.com (GSD library)
• On CD ROM from Endress+Hauser
Structure of GSD files from Endress+Hauser
For Endress+Hauser field transmitters with PROFIBUS interface, all the data which are needed for
configuration are contained in one file. Once unpacked, this file will create the following structure:
• Revision #xx stands for the corresponding device version. Device-specific bitmaps can be found
in the directories "BMP" and "DIB". The utilization of these will depend on the configuration
software that is being used.
• The GSD files are saved in the "Extended" and "Standard" subdirectories of the "GSD" folder.
Information relating to the implementation of the field transmitter and any dependencies in the
device software can be found in the "Info" folder. Please read this information carefully before
configuring. The files with the extension .200 can be found in the "TypDat" folder.
Standard and extended formats
The modules of some GSD files are transmitted with an extended identification (e.g. 0x42, 0x84,
0x08, 0x05). These GSD files can be found in the "Extended" folder. All GSD files that have a
standard identification (e.g. 0x94) can be found in the "Standard" folder.
When integrating field transmitters, the GSD files with the extended identification should be used
first. If, however, the integration is not successful, the standard GSD should be used. This
differentiation is the result of specific implementation in the master systems.
Contents of the download file from the Internet and the CD-ROM:
• All Endress+Hauser GSD files
• Endress+Hauser type files
• Endress+Hauser bitmap files
• Useful information relating to the devices

Working with GSD / type files
The GSD files must be integrated into the automation system.
Depending on the software that is being used, the GSD files can be copied to the program-specific
directory or can be read into the database using the import function within the configuration
software.
Example 1:
In the case of the configuration software Siemens STEP 7 (Siemens PLC S7-300 / 400) the files are
copied to the subdirectory ...\ siemens \ step7 \ s7data \ gsd.
The GSD files also have bitmap files. These bitmap files are used to display the measuring points in
image form. The bitmap files must be saved to the directory ...\ siemens \ step7 \ s7data \ nsbmp.
Example 2:
If you have a PLC Siemens S5 where the PROFIBUS DP network is configured with the
configuration software COM ET 200, you will have to use the type files (x.200 files).
If you are using configuration software other than that referred to above, ask your PLC manufacturer
which directory you should use.
Compatibility of Profile 2.0 and 3.0 devices
It is possible to operate Profile 2.0 and 3.0 devices with different GSD files in one system using one
DP master as the cyclic data for the automation system in both profile versions are compatible.

Proline Prowirl 72 PROFIBUS PA6 Commissioning
6.3.1Compatibility with previous model Prowirl 77
In the event of the device being replaced, Prowirl 72 PROFIBUS PA ensures compatibility of the
cyclic data with the previous model Prowirl 77 PROFIBUS PA with Profile version 2.0 (ID No.
1510).
It is possible to replace a Prowirl 77 PROFIBUS PA device with a Prowirl 72 PROFIBUS PA without
adjusting the planning of the PROFIBUS DP/PA network in the automation device even though the
devices differ with regard to their name and their ID number. Once replaced, the device is
recognized either automatically (factory setting) or this can be set manually.
Automatic recognition (factory setting)
The Prowirl 72 PROFIBUS PA automatically recognizes the measuring device (Prowirl 77
PROFIBUS PA) planned in the automation system and makes the same input and output data and
measured value status information available for cyclic data exchange.
Manual setting
The manual setting is made in the manufacturer-specific device matrix in the SELECTION GSD
(V6H1) parameter, see Page 119. When replacing instead of a Prowirl 77 PROFIBUS PA, "Prowirl
77" must be selected in the SELECTION GSD parameter.
Then the Prowirl 72 PROFIBUS PA makes the same input and output data and measured value
status information available for cyclic data exchange.
!
Note!
• At 16 mA, the current consumption of the Prowirl 72 PROFIBUS PA is slightly higher than that
of the Prowirl 77 PROFIBUS PA (12 mA). After replacing the devices, make sure that the sum of
the base currents of all the PROFIBUS PA bus users does not exceed the maximum permitted feed
current of the bus feed device.
• When acyclically configuring the Prowirl 72 PROFIBUS PA by means of an operating program
(Class 2 master), access takes place directly via the block structure or the parameters of the
measuring device.
• If parameters in the device to be replaced (Prowirl 77 PROFIBUS PA) have been changed
(parameter setting no longer corresponds to the original factory setting), these parameters have to
be adjusted accordingly in the new Prowirl 72 PROFIBUS PA in use by means of an operating
program (Class 2 master).
Example:
The assignment of low flow cut off was changed from volume flow (factory setting) to corrected
volume flow in a Prowirl 77 PROFIBUS PA which is in use. This measuring device is now being
replaced by a Prowirl 72 PROFIBUS PA. Once the device has been replaced, the low flow cut off
assignment in the Prowirl 72 PROFIBUS also has to be adjusted manually, i.e. changed to
corrected volume flow to ensure that the device behaves identically.
Procedure when replacing the measuring devices
Replacing a Prowirl 77 PROFIBUS PA with a Prowirl 72 PROFIBUS PA
• Remove the Prowirl 77 PROFIBUS PA
• Configure the device address (see Page 42).
The same device address as that configured for the Prowirl 77 PROFIBUS PA must be used.
• Check that the maximum permitted feed current of the bus feed device is not exceeded. This could be caused by the
higher current consumption of the Prowirl 72 PROFIBUS PA.
• Connect the Prowirl 72 PROFIBUS PA
• If necessary, the following settings must be adjusted (if the factory setting had been altered):
– Configuration of the application-specific parameters
– Configuration of the units for the process variables

6.4Cyclic data exchange
In the case of PROFIBUS PA, the cyclic transmission of analog values to the automation system is
effected in data blocks of 5 bytes. The measured value is portrayed in the first 4 bytes in the form
of floating point numbers in accordance with IEEE 754 standard (see IEEE floating point number).
The 5th byte contains status information pertaining to the measured value which is implemented in
accordance with the Profile 3.0 Specification ( Page 48). The status is indicated on the display of
the device, if present.
!
Note!
An exact description of the data types can be found in Section 11 "Operation via PROFIBUS PA" on
Page 95 ff.
IEEE floating point number
Converting a hexadecimal value to an IEEE floating point number for measured value acquisition.
The measured values are shown in numerical format IEEE-754 in the following manner and are
transferred to the Class 1 master:
The analog values transmitted by Prowirl 72 during cyclic data exchange are:
• Volume flow
• Calculated mass flow
• Corrected volume flow
• Totalizer and the corresponding controls
• Control for manufacturer-specific functions
!
Note!
The totalizer can be configured in various combinations with the totalizer controls.
It is possible to configure the totalizer only, or additionally integrate one or two control blocks in
order to reset the totalizer or stop totalizing, for example.
The configuration is explained in detail on Page 55.
The block model illustrated ( Fig. 26) shows which input and output data Prowirl 72 provides
for cyclic data exchange.

Input data
Input data are: volume flow, calculated mass flow, corrected volume flow and totalizer. The current
measured value can be transmitted to the automation system using these measured variables.
Data transfer from Prowirl to the automation system
The input and output bytes are structured in a fixed sequence. If addressing is effected automatically

Controls (output data), manufacturer-specific
The device is capable of processing controls (output data) during cyclic data exchange e.g. the
switching on of positive zero return.

Controls for the totalizer (output data)
These functions allow the totalizer to be controlled from the automation system. The following
controls are possible:
• Totalizing
• Resetting
• Activation of a preset value
• Balancing
• Only positive flow detection
• Only negative flow detection (Prowirl 72 cannot measure any negative flow)
• Stop totalizing

Note!
• "One" control can be executed through the cyclic data exchange each time the output byte

a control.
• It is only possible to preset a predefined totalizer value via the Class 2 master or the FieldCare
FieldCare service and configuration software!
Example for SET_TOT and MODE_TOT:
If the control variable SET_TOT is set to "1" (1 = reset the totalizer), the value of the totalizer is set
to "0". The value of the totalizer will now be added up starting from "0".
If the totalizer is to retain the value "0", it is necessary to set the control variable MODE_TOT to "3"
(3 = STOP totalizing). The totalizer will now stop adding up. The totalizer can then be reset to "1"
using control variable SET_TOT (1 = reset the totalizer).

Factory settings for the cyclic measured variables
The following measured variables are configured in Prowirl 72 at the factory:
• Volume flow (channel 273)
• Calculated mass flow (channel 277)
• Corrected volume flow (channel 398)
• Totalizer (with control variable SET_TOT and MODE_TOT)
• Control (manufacturer-specific)
If all measured variables are not required, you can use the placeholder "EMTY_MODULE" (0x00)
- which can be found in the GSD file - to deactivate individual measured variables using the
configuration software of the Class 1 master. Examples of configuration Page 56.
!
"
Note!
Only activate the data blocks which are processed in the automation system. This improves the data
throughput rate of a PROFIBUS PA network.
A double-arrow symbol flashes on the display to show that the device is communicating with the
automation system.
Caution!
• It is essential to adhere to the following sequence when configuring the measured variables:
Analog Input, Totalizer and Control.
• The device has to be reset once a new measured variable configuration has been loaded to the
automation system. This can be effected in either of two ways:
– Via a Class 2 master
– Switching supply voltage OFF and then ON again.
System units
The measured values are transmitted in the system units, as described in the table on Page 54, to
the automation system via cyclic data exchange.
Examples of configuration
The configuration of a PROFIBUS DP system is normally effected in the following manner:
1.The field devices (Prowirl 72 PA) which are to be configured are integrated into the
configuration program of the automation system via the PROFIBUS DP network. The GSD file
is used here. Measured variables required can be configured "off line" using the configuration
software.
2.The automation system's user program should now be programmed. The user program
controls the input and output data and defines the location of the measured variables so that
they can be processed further.
An additional measured value configuration module may have to be used in the case of
automation systems which do not support the IEEE-754 floating point format.
It may also be necessary to change the byte sequence (byte swapping) depending on the type
of data management employed in the automation system (little-endian format or big-endian
format).
3.When configuration is completed, this is transferred to the automation system in the form of a
binary file.
4.The system can be started now. The automation system establishes a connection to the
configured devices. The device parameters which are relevant for the process can now be set
using a Class 2 master, e.g. with Commuwin II ( Page 47).

6.5Acyclic data exchange
Acyclic data exchange is used to transfer parameters during commissioning and maintenance or to
display other measured variables that are not contained in the useful cyclic data traffic. Thus,
parameters for recognizing, for controlling or for adjusting can be changed in the various blocks
(Physical Block, Transducer Block, function block) while the device is involved in cyclic data
exchange with a PLC.
When observing acyclic communication, a distinction must be made between two types:
6.5.1Class 2 master acyclic (MS2AC)
MS2AC deals with acyclic communication between a field device and a Class 2 master (e.g.
Fieldcare, Commuwin, PDM etc., see Page 35). Here, the master opens a communication channel
by means of an SAP (service access point) to access the device.
A Class 2 master must be made aware of all the parameters which should be exchanged with a
device by means of PROFIBUS. This assignment is made to each individual parameter either in a
device description (DD), a DTM (Device Type Manager) or within a software component in the
master via slot and index addressing.
The following should be noted with MS2AC communication:
• As already explained, a Class 2 master accesses a device by means of special SAPs. Thus, the
number of Class 2 masters that can simultaneously communicate with a device is restricted to the
number of SAPs made available for this communication.
• When a Class 2 master is used, the cycle time of the bus system increases.
This should be taken into account when programming the control system used.
6.5.2Class 1 master acyclic (MS1AC)
In the case of MS1AC, a cyclic master, which is already reading the cyclic data from the device or
writing the data to the device, opens the communication channel via the SAP 0x33 (special service
access point for MS1AC) and can then, like a Class 2 master, acyclically read or write a parameter
by means of the slot and the index (if supported).
The following should be noted with MS1AC communication:
• At present, there are very few PROFIBUS masters on the market that support this kind of
communication.
• Not all PROFIBUS devices support MS1AC.
• In the user program, you must be aware that constant parameter writing (e.g. with every program
cycle) can drastically reduce the operating life of a device. Parameters written acyclically are
written to memory modules (EEPROM, Flash, etc.). These are resistant to voltage. These memory
modules are only designed for a limited number of writes. This number of writes is not even
nearly reached in normal operation without MS1AC (during configuration). This maximum figure
can be quickly reached as a result of incorrect programming and thus the operating time of a
device can be drastically reduced.
The measuring device supports MS2AC communication with 2 available SAPs.
MS1AC communication is supported by the device.
The memory module is designed for 10

writes.

9.2System error messages
General notes
The measuring device always assigns system and process errors which occur to two types of error
messages, resulting in different weightings.
"Fault message" error message type:
• If this message occurs, operation is immediately interrupted or stopped.
• Display on the PROFIBUS Fault messages are relayed to downstream function blocks or higherlevel process control systems with the status "BAD" of the corresponding process variable.
• Local display A lightning symbol ($) flashes on the display
"Notice message" error message type:
• Normal operation continues despite this message.
• Display on the PROFIBUS Notice messages are relayed to downstream function blocks or
higher-level process control systems with the status "UNC(ERTAIN)" of the corresponding
process variable.
• Local display An exclamation mark (!) flashes on the display.
Serious system errors, e.g. electronic module defects, are always categorized and displayed as "fault
messages" by the measuring device. On the other hand, the measuring system interprets simulations
and positive zero return as "notice messages".

9.4Process errors without messages
SymptomsRemedial measures
Remark:
You may have to change or correct settings in certain parameters in order to rectify the fault. The parameters listed
below, such as AMPLIFICATION etc., are described in detail in the Section »Operation via PROFIBUS PA« on
Page 95 ff.
No flow signal• For liquids:
Check whether the piping is completely filled. The piping must always be
completely filled for accurate and reliable flow measurement.
• Check whether all the packaging material, including the meter body protective
covers, was completely removed before mounting the device.
• Check whether the desired electrical output signal was connected correctly.
Flow signal even though there
is no flow
Faulty or highly fluctuating
flow signal
Check whether the device is subject to particularly strong vibrations. If so, a flow can
be displayed even if the fluid is at a standstill, depending on the frequency and
direction of the vibration.
Remedial measures at the device:
• Turn the sensor 90° (pay attention to the installation conditions, Page 11 ff.).
The measuring system is most sensitive to vibrations which follow in the direction
of the sensor. Vibrations have less of an effect on the device in the other axes.
• The amplification can be altered using the AMPLIFICATION function (see
Page 125).
Remedy through constructive measures during installation:
• If the source of the vibration (e.g. pump or a valve) has been identified, the
vibrations can be reduced by decoupling or supporting the source.
• Support the piping near the device.
If these measures do not solve the problem, your Endress+Hauser service organization
can adjust the filters of the device to suit your special application.
• The fluid is not sufficiently single-phase or homogeneous. The piping must always
be completely filled and the fluid must be single-phase and homogeneous for
accurate and reliable flow measurement.
• In many instances, the following measures can be taken to improve the
measurement result even under non-ideal conditions:
– For liquids with a low gas content in horizontal pipework, it helps to install the
device with the head pointing downwards or to the side. This improves the
measuring signal since the sensor is not in the area where gas accumulates when
this type of installation is used.
– For liquids with a low solids content, avoid installing the device with the
electronics housing pointing downwards.
– For steam or gases with a low liquid content, avoid installing the device with the
electronics housing pointing downwards.
• The inlet and outlet runs must be present as per the installation instructions
( Page 14).
• Suitable seals with an internal diameter not smaller than the pipe internal diameter
must be installed and correctly centered.
• The static pressure must be large enough to rule out cavitation in the area of the
sensor.

SymptomsRemedial measures
Faulty or highly fluctuating
flow signal (contd.)
The fault cannot be rectified
or some other fault not
described above has occurred.
In these instances, please
contact your Endress+Hauser
service organization.
• Check whether the correct fluid was selected in the APPLICATION function (see
Page 112). The setting in this function determines the filter settings and can thus
have an effect on the measuring range.
• Check whether the data for the K-factor on the nameplate match the data in the KFACTOR parameter (see Page 123).
• Check whether the device is installed correctly in the direction of flow.
• Check whether the nominal diameter of the mating pipe and the device match
(see Page 115).
• The flow must be in the measuring range of the device ( Page 79). The start of
measuring range depends on the density and the viscosity of the fluid. Density and
viscosity depend on temperature. Density also depends on the process pressure in
the case of gases.
• Check whether the operating pressure is affected by pressure pulsations (e.g. from
piston pumps). The pulsations can affect vortex shedding if they have a frequency
similar to the vortex frequency.
• Check whether the correct engineering unit was selected for the flow or totalizer.
The following options are available for tackling problems of this nature:
Request the services of an Endress+Hauser service technician
If you contact our service organization to have a service technician sent out, please be
ready with the following information:
– A brief description of the error with information on the application.
– Nameplate specifications ( Page 7 ff.): order code and serial number.
Return devices to Endress+Hauser
The procedures on Page 6 must be carried out before you return a measuring device
requiring repair or calibration to Endress+Hauser.
Always enclose a fully completed "Declaration of Contamination" form with the
flowmeter. A copy of the form can be found at the end of these Operating Instructions.

Measuring principleVortex flow measurement on the principle of the Karman vortex street.
Measuring systemThe measuring system consists of a transmitter and a sensor:
• Transmitter Proline Prowirl 72 PROFIBUS PA
• Prowirl F or W sensor
Two versions are available:
•Compact version:
Transmitter and sensor form a single mechanical unit.
• Remote version:
Sensor is mounted separate from the transmitter.
10.1.3Input
Measured variableVolumetric flow (volume flow) is proportional to the frequency of vortex shedding after the bluff
body.
Volume flow can be output as the output variable, as can the calculated mass flow or corrected
volume flow if process conditions are constant.
Measuring rangeThe measuring range depends on the fluid and the pipe diameter.
Start of measuring range:
Depends on the density and the Reynolds number (Re
= 4000, Re
min
The Reynolds number is dimensionless and represents the ratio of the inertia force of a fluid to its
viscous force. It is used to characterize the flow. The Reynolds number is calculated as follows:
= 20000).
linear
Re = Reynolds number, Q = flow, di = internal diameter, = dynamic viscosity, = density
46 m/s (151 ft/s) or Mach 0.3
(depending on which is smaller)
75 m/s (246 ft/s) or Mach 0.3
(depending on which is smaller)
120 m/s (394 ft/s) or Mach 0.3
(depending on which is smaller)
Calibrated range: up to 75 m/s (246 ft/s)
!Note!
By using the selection and planning program "Applicator", you can determine the exact values for
the fluid you use. You can obtain the Applicator from your Endress+Hauser sales center or on the
Internet under www.endress.com.

Diameter jump correction
Prowirl 72 can correct shifts in the calibration factor which are caused by a jump in the diameter
between the device flange and the mating pipe. The diameter jump should only be corrected within
the following limit values (for which test measurements have also been performed).
Flange connection:
DN 15 (½"): ±20% of the internal diameter
DN 25 (1"): ±15% of the internal diameter
DN 40 (1½"): ±12% of the internal diameter
DN 50 ( 2"): ±10% of the internal diameter
Wafer:
DN 15 (½"): ±15% of the internal diameter
DN 25 (1"): ±12% of the internal diameter

Reaction time/step response
time
Influence of ambient
temperature
If all the configurable functions are set to 0, you must reckon with a reaction time/step response
time of 200 ms for vortex frequencies of 10 Hz and higher. For other settings where vortex
frequencies are 10 Hz and higher, a reaction time/step response time of 100 ms has to be added to
the overall filter reaction time.

Pressure measuring device
approval
The measuring devices can be ordered with or without PED (Pressure Equipment Directive). If
a device with PED is required, this must be ordered explicitly. For devices with nominal diameters
less than or equal to DN 25 (1"), this is neither possible nor necessary.
• With the identification PED/G1/III on the sensor nameplate, Endress+Hauser confirms
conformity with the "Basic safety requirements" of Appendix I of the Pressure Equipment
Directive 97/23/EC.
• Devices with this identification (with PED) are suitable for the following types of fluid:
– Fluids of Group 1 and 2 with a steam pressure of greater or less than 0.5 bar (7.3 psi)
– Unstable gases
• Devices without this identification (without PED) are designed and manufactured according to
good engineering practice. They correspond to the requirements of Art. 3, Section 3 of the
Pressure Equipment Directive 97/23/EC. Their application is illustrated in Diagrams 6 to 9 in
Appendix II of the Pressure Equipment Directive 97/23/EC.

11Operation via PROFIBUS PA
11.1Block model
In the PROFIBUS PA interface, all the device parameters are categorized according to their
functional properties and task and are generally assigned to three different blocks. A block may be
regarded as a container in which parameters and the associated functionalities are contained.
A PROFIBUS PA device has the following block types:
• A Physical Block (device block)
The Physical Block contains all the device-specific features of the unit.
• One or more Transducer Blocks
The Transducer Block contains all the measuring and device-specific parameters of the device.
The measurement principles (e.g. flow) are depicted in the Transducer Blocks in accordance with
the PROFIBUS PA Profile 3.0 Specification.
• One or more function blocks
Function blocks contain the automation functions of the device. We distinguish between different
function blocks, e.g. Analog Input function block, Analog Output function block, Totalizer Block,
etc. Each of these function blocks is used to process different application functions.
A number of automation-related tasks can be implemented with these blocks. In addition to these
blocks, a field device may have any number of other blocks, e.g. several Analog Input function
blocks if more than one process variable is available from the field device.
A0003881-EN
Fig. 34:Block types of a PROFIBUS PA device
The sensor signal is first prepared specifically for the flow in the measuring block (the Transducer
Block). The process variable is then passed to the Analog Input and Totalizer function block for
technical processing (e.g. scaling, limit value processing). The process variable goes through the
entire function block algorithm and is available to the process control system as an output variable.

11.2Physical Block (device block)
A Physical Block contains all the data that clearly identify and characterize the field device. It is an
electronic version of a nameplate on the field device. Parameters of the Physical Block include the
device type, device name, manufacturer ID, serial number, etc.
A further task of the Physical Block is the management of overall parameters and functions that have
an influence on the execution of the remaining blocks in the field device. The Physical Block is thus
the central unit that also checks the device status and thereby influences or controls the operability
of the other blocks and thus also of the device.
11.2.1Write protection
Hardware write protection for the device parameters is enabled and disabled by means of a DIP
switch on the amplifier board ( Page 44).
The HW WRITE PROTECT parameter ( Page 98) shows the status of the hardware write
protection. The following statuses are possible:
1 Hardware write protection enabled, it is not possible to write to the device
0 Hardware write protection disabled, device data can be overwritten
It is also possible to set software write protection to prevent all parameters from being acyclically
overwritten. This lock is set by an entry in the WRITE LOCKING parameter ( Page 98). The
following entries are permitted:
2457 Device data can be overwritten (factory setting)
0 Device data cannot be overwritten
11.2.2Physical Block parameters
The following table shows all the available parameters of the Physical Block.
Abbreviations used in the table:
•R = Read

In the configuration phase, each PROFIBUS device must
check an ID number allocated by the PNO (PROFIBUS
User Organization). Along with this device-specific ID
number there are also PROFILE ID numbers that have to
be accepted in the configuration phase as well, for the
purposes of interchangeability between devices of different
make. In this case the device might, under certain
circumstances, reduce the functionality for cyclic data to a
profile-defined scope.

General information on the MODE BLK parameter group:
There are three elements in this parameter group:
• The current operating mode of the block (Actual Mode)
• The modes supported by the block (Permitted Mode)
• The normal operating mode (Normal Mode)
A distinction is drawn between "automatic operation" (AUTO), manual user intervention
(MAN), local override (LO) and the "out-of-service" mode (O/S).
A function block generally offers a choice of operating modes, whereas the other block types
only work in the AUTO mode, for example.

Static parameters whose values change during
optimization or configuration increment the ST REV
parameter by 1.
This supports parameter-revision management.
The Static Revision Counter can show a higher value if
several parameters change within a very short period of
time, for example when parameters are loaded to the
device from Commuwin II.
This counter can never be reset, nor does it return to a
default setting even after a device reset. If the counter
overflows (16 bits), it starts again at 1.
