1 Safety instructions
1.1 Designated use
The measuring system is used to measure the flow of saturated steam, superheated steam, gases and
liquids. The measured variables volume flow and temperature are measured primarily. From these
values, the device can used stored data on the density and enthalpy to calculate and output the mass
flow and heat flow for example.
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.
1.2 Installation, 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 owner-
operator. 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.
• Always note the regulations applicable in your country to the operation, maintenance and repair
of electrical devices. Special instructions relating to the device can be found in the relevant
sections of this documentation.
1.3 Operational 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 (0Europe, 2USA, 1Canada).
• 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.

10 Endress+Hauser
1.4 Return
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.
!Note:
A copy of the "Declaration of Contamination" can be found at the end of these Operating
Instructions.
#Warning:
• Do not return a measuring device if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.
• Costs incurred for waste disposal and injury (caustic burns, etc.) due to inadequate cleaning will
be charged to the owner-operator.
1.5 Notes on safety conventions and icons
The devices are designed to meet state-of-the-art safety requirements, have been tested and left the
factory in a condition in which they are safe to operate.
The devices comply with the applicable standards and regulations in accordance with EN 61010-1
"Protection Measures for Electrical Equipment for Measurement, Control, Regulation and
Laboratory Procedures". They can, however, be a source of danger if used incorrectly or for anything
other than the designated use.
Consequently, always pay particular attention to the safety instructions indicated in these Operating
Instructions by the following symbols:
#Warning:
"Warning" indicates an action or procedure which, if not performed correctly, can result in injury
or a safety hazard. Comply strictly with the instructions and proceed with care.
"Caution:
"Caution" indicates an action or procedure which, if not performed correctly, can result in incorrect
operation or destruction of the device. Comply strictly with the instructions.
!Note:
"Note" indicates an action or procedure which, if not performed correctly, can have an indirect
effect on operation or trigger an unexpected response on the part of the device.

3.1 Incoming acceptance, transport, storage
3.1.1 Incoming 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.
3.1.2 Transport
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 centre 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.

3.1.3 Storage
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.

3.2 Installation 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 19).
• The maximum permitted ambient temperatures (see Page 86) and fluid temperatures (see
Page 87) must be observed.
• Pay particular attention to the notes on orientation and piping insulation (see Page 17 ff.).
• 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 D MATING PIPE function on Page 139).
• 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.
3.2.1 Installation 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).

3.2.2 Orientation
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 86) 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 73 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.

3.2.3 Heat insulation
Some fluids require suitable measures to avoid heat transfer at the sensor to ensure optimum
temperature measurement and mass calculation. 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 diagrams. These apply equally to both
the compact version and the sensor in the remote version.
A0001868
Fig. 7: 1 = Flanged version, 2 = Wafer version
"Caution:
Danger of electronics overheating!
• Therefore, make sure that the adapter between sensor and transmitter and the connection
housing of the remote version are always exposed.
• Note that a certain orientation might be required, depending on the fluid temperature
→ Page 17.
• Information on permissible temperature ranges → Page 86.

Outlet runs with pressure measuring points
If pressure and temperature measuring points are installed after the device, please ensure there is a
large enough distance between the device and the measuring point so there are no negative effects
on vortex formation in the sensor.

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:
Δp [mbar] = 0.0085 · ρ[kg/m³] · v² [m/s]
3.2.5 Vibrations
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.
3.2.6 Limiting flow
See the information on Page 81 and 88.
• Example with steam
p = 10 bar abs
t = 240 °C → ρ = 4.39 kg/m³
v = 40 m/s
Δp = 0.0085 · 4.39 · 40² = 59.7 mbar
• Example with H2O condensate (80 °C)
ρ = 965 kg/m³
v = 2.5 m/s
Δp = 0.0085 · 965 · 2.5² = 51.3 mbar
