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...300 may not be lifted at the transmitter housing or at the
connection housing of the remote version when transporting (see Fig. 3). 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. 3: Instructions for transporting sensors with DN 40...300
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 –40...+80 °C
(ATEX II 1/2 GD version/dust ignition-proof –20...+55 °C).
• When in storage, the device should not be exposed to direct sunlight in order to avoid
impermissibly high surface temperatures.

3 Installation Proline Prowirl 72
12 Endress + Hauser
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 14).
• The maximum permitted ambient temperatures (see Page 63) and fluid temperatures
(see Page 63) 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 97).
• The correct operation of the measuring system is not influenced by plant vibrations up to 1 g,
10...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.
3.2.1 Dimensions
The dimensions and lengths of the sensor and transmitter can be found in the Technical Information
TI070D/06/en.
3.2.2 Installation location
We recommend you observe the following dimensions to guarantee problem-free access to the
device for service purposes:
• Minimum spacing in all directions = 100 mm
• Necessary cable length: L + 150 mm
A0001870
Fig. 4: A = Minimum spacing in all directions, L = cable length
3.2.3 Orientation
The device can generally be installed in any position in the piping.
In the case of liquids, there should be upward flow in vertical pipes to avoid partial pipe filling (see
orientation A).
In the case of hot fluids (e.g. steam or fluid temperature ≥ 200 °C), select orientation C or D so that
the permitted ambient temperature of the electronics is not exceeded. Orientations B and D are
recommended for very cold fluids (e.g. liquid nitrogen) (see Page 13).
L
A

Proline Prowirl 72 3 Installation
Endress + Hauser 13
Orientations B, C and D are possible with horizontal installation (see Page 13).
The arrow indicated on the device must always point in the direction of flow in all orientations.
"Caution!
• If fluid temperature is ≥200 °C, orientation B is not permitted for the wafer version
(Prowirl 72 W) with a nominal diameter of DN 100 and DN 150.
• In case of vertical orientation and downward flowing liquid, the piping has always to be
completely filled.

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 diagrams. These apply equally to both
the compact version and the sensor in the remote version.

Fig. 6: 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 is always exposed.
• Note that a certain orientation might be required, depending on the fluid temperature →Page 12.
• Information on permissible temperature ranges →Page 63.

Outlet runs with pressure and temperature 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.

Fig. 8: Installation of pressure measuring point (PT) and temperature measuring point (TT)
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 x DN with complete accuracy.
A0001887
Fig. 9: Perforated plate flow conditioner
Examples of pressure loss for flow conditioner
The pressure loss for flow conditioners is calculated as follows:
∆p [mbar] = 0.0085 · ρ[kg/m³] · v² [m/s]
3.2.6 Vibrations
The correct operation of the measuring system is not influenced by plant vibrations up to 1 g,
10...500 Hz. Consequently, the sensors require no special measures for attachment.
3.2.7 Limiting flow
See the information on Page 59 and 65.
• Example with steam
p = 10 bar abs
t = 240 °C → ρ = 4.39 kg/m³
v = 40 m/s
∆p = 0.0085 · 4.39 · 40² = 59.7 mbar
• Example with H2O condensate (80 °C)
ρ = 965 kg/m³
v = 2.5 m/s
∆p = 0.0085 · 965 · 2.5² = 51.3 mbar

3.3.1 Mounting the 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. For this reason, the seals
supplied by Endress+Hauser for the wafer version have a slightly larger internal diameter than the
measuring pipe.
• Ensure that the arrow on the measuring pipe matches the direction of flow in the piping.
• Lengths:
– Prowirl W (wafer version): 65 mm
– 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.
