1 Safety Instructions
1.1 Correct usage
•Prowirl 77 is only to be used for measuring the volumentric flowrate of saturated
steam, superheated steam, gases and liquids. If the process pressure and
temperature are constant, then Prowirl 77 can also indicate the flowrate in units of
mass, energy or corrected volume.
•The manufacturer assumes no liability for damage caused by incorrect use of the
instrument.
•Instruments which are ordered with hazardous area approvals are supplied with a
separate “Ex documentation”, which is an integral part of this Operating Manual.
The instructions and connected loads provided in this supplement must be closely
observed! An appropriate pictogram is shown on the front page of the
Ex documentation according to the approval given and the test centre.
1.2 Dangers and Notes
All instruments are designed to meet state-of-the-art safety requirements, have been
tested, and have left the works in an operationally perfectly safe condition.
The devices were developed according to EN 61010 “Protection Measures for
Electrical Equipment for Measurement, Control, Regulation and Laboratory Proce-
dures”. A hazardous situation may occur if the flowmeter is not used for the purpose it
was designed for or is used incorrectly. Please carefully note the information
provided in this Operating Manual indicated by the pictograms:
Warning!
A “warning” indicates actions or procedures which, if not performed correctly, may
lead to personal injury or a safety hazard.
Please strictly observe the instructions supplied and proceed carefully.
Caution!
A “caution” indicates actions or procedures which, if not performed correctly, may
lead to faulty operation or destruction of the instrument. Please strictly observe the
respective instructions.
Note!
A “note” indicates actions or procedures which, if not performed correctly, may indi-
rectly affect operation or lead to an unexpected instrument response.
1.3 Operational safety
•The Prowirl 77 measuring system fulfills the general safety regulations according to
EN 61010 and the interference immunity regulations (EMC) according to European
standard EN 50081 Part 1 and 2 / EN 50082 Part 1 and 2 as well as NAMUR recom-
mendations.
•Housing ingress protection IP 67 according to EN 60529.
•A comprehensive self-monitoring feature of the measuring system ensures high
operational safety.
•After loss of power supply (which is provided by the field bus), the configuration
data of the measuring system remain in the EEPROM (without batteries).
The totalizer remains on the value last shown.
Warning!

1.4 Personnel for Installation, Start-up and Operation
•Mounting, electrical installation, start-up and maintenance of the instrument may
only be carried out by trained personnel authorised by the operator of the facility.
Personnel must absolutely and without fail read and understand this Operating
Manual before carrying out its instructions.
•The instrument may only be operated by personnel who are authorised and trained
by the operator of the facility. All instructions in this manual are to be observed
without fail.
•In case of corrosive fluids, the compatibility of the material of all wetted parts such
as measuring pipe, bluff body, sensor and gaskets is to be verified. This also ap-
plies to fluids used to clean the Prowirl 77 flowmeter. Endress+Hauser will be
pleased to provide you with any help required.
•The installer has to make sure that the measuring system is correctly wired up
according to the wiring diagrams. The complete bus system is to be grounded.
Please observe all provisions valid for your country pertaining to opening and repair
of electrical devices.
1.5 Repairs, Dangerous Chemicals
The following procedures must be carried out before a Prowirl 77 is sent to
Endress+Hauser for repair:
•A note must be enclosed with the instrument, containing a description of the fault,
the application and the chemical and physical properties of the fluid being
measured.
•Remove all residue which may be present. Pay special attention to the gasket
grooves and crevices where fluid may be present. This is especially important if the
fluid is dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive,
etc.
•No instrument should be returned to us without all dangerous material being
removed first.
Incomplete cleaning of the instrument may result in waste disposal requirements or
cause harm to personnel (burns, etc.). Any costs arising from this will be charged to
the operator of the instrument.
1.6 Technical Improvements
The manufacturer reserves the right to modify technical data without prior notice.
Your local E+H Sales Office will supply you with all current information and any
updates to this Operating Manual.
There is no longer any contact protection once the housing cover is removed

2 System Description
The Prowirl 77 vortex flowmeter measures the volumetric flow of steam, gases and liq-
uids for fluid temperatures in the range of –200...+400 °C and at nominal pressures of
up to PN 160 / ANSI class 600.
Prowirl 77 measures the volumetric flow at operating conditions. If the process
pressure and temperature are constant, Prowirl 77 can be programmed to supply the
flowrate in mass, energy or corrected volume units.
2.1 Prowirl 77 Measuring System
A measuring system consists of:
•Prowirl 77 transmitter
•Prowirl 77 W, Prowirl 77 F or Prowirl 77 H body
The Prowirl 77 transmitter is available in different versions. The transmitter versions
differ in the type of electrical output signals and digital communication capabilities.
This Operating Manual describes the “PROFIBUS-PA”version.
The Prowirl 77 transmitter is available in two other versions:
•Version: “PFM”
•Version: “4...20 mA”(optional with HART)
Operation of those versions is not included in this Operating Manual. Separate
Operating Manuals for those instruments are available on request.

The various Prowirl 77 transmitters can be freely combined with all meter body
versions. This guarantees flexibility when matching a complete meter to specific
industrial process conditions.

3 Mounting and Installation
3.1 General Information
Protection IP 67 (EN 60529)
The instruments fulfil all the requirements for IP 67. The following points must always
be observed in order to ensure protection to IP 67 after istallation in the field or after
servicing:
•Housing gaskets must be clean and
undamaged when inserted in the
gasket groove. The gaskets may need
to be dried, cleaned or replaced.
•All housing screws and the housing
cover must be firmly tightened.
•The cables used for connecting
must have an outer diameter in the
specified range.
•The cable gland must be firmly
tightened (see Fig. 2).
•The cable must loop down before
entering the cable gland to ensure that
no moisture can enter it
(see Fig. 2).
•Any unused cable glands are to be
replaced with a plug.
•The protective bushing should not be
removed from the cable gland.
Temperature ranges
•The maximum approved ambient and process temperatures must be observed
(see page 56).
•Observe also the instructions on piping insulation and mounting position
(see page 11).

3.2 Installation
A vortex flowmeter requires a fully developed flow profile as a prerequisite for
measuring volume accurately. The following points must therefore be noted when
mounting the Prowirl 77 in the pipeline.
Pipe inner diameter
When ordering, ensure that the nominal diameter and pipe schedule (DIN/ANSI/JIS)
are correct, since calibration of the flowmeter and therefore the achieveable accuracy
of the measuring point are dependent on these specifications.
Inlet and outlet sections
To ensure an undisturbed flow profile,
the vortex flowmeter should be mounted
upstream of any flow disturbances such
as pipe elbows, reducers or valves,
otherwise the longest possible section of
piping should be between the distur-
bance and the flowmeter. The figures on
the left show the minimum section of
straight piping
downstream of the distur-
bance as multiples of the nominal diame-
ter of the pipe in DN. If two or more flow
disturbances are located upstream, then
the longest inlet section recommended
should be used.
There must also be a straight outlet
section of sufficient length downstream
from the flowmeter to ensure that the vor-
tices are properly developed.
Flow conditioner
With limited space and large pipes, it
is not always possible to use the inlet
sections given above. In such cases the
specially developed perforated plate flow
conditioner (see page 53 ff.) can be fitted
as shown on the left. The flow conditioner
is held between two piping flanges and
centred with the flange bolts. It reduces
the length of the inlet section downstream
from flow disturbances to 10 x DN while
maintaining high accuracy measurement.
