!Note!
• The individual functions are described in the "Description of Device Functions" section (ä95).
• The display returns to the QUICK SETUP COMMISSION cell (ä109) if you press the Pkey combination (Esc)
during parameter interrogation. The configuration settings already made remain valid, however.
mThe following parameters are reset to the factory setting if the fluid selected is changed:
In group Parameter
User interface 100% value line 1, 100% value line 2
Current output All parameters
Frequency output All parameters
Process parameter All relevant parameters
nOnly the output (current output or frequency output) not yet configured is offered for selection after the first cycle.
oThe "YES" option appears as long as a free output is available. "NO" is displayed when no further outputs are
available.
pWhen "YES" is selected, the volume flow is assigned to line 1 of the local display and the temperature to line 2.
qIf "HART INPUT GAUGE" or "HART INPUT ABSOLUTE" is selected in the PRESSURE TYPE function, the HART
INPUT field automatically switches to "PRESSURE".
If "HART INPUT ABSOLUTE" or "PREDEFINED VALUE" is selected, the AMBIENT PRESSURE field is not displayed.
If "PREDEFINED VALUE" is selected, the OPERATING PRESSURE field is displayed.
If "PREDEFINED VALUE" is selected, the ERROR VAL. PRESS field is not displayed.
rIf "SATURATED STEAM DELTA HEAT" or "WATER DELTA HEAT" is selected, the following notice message is
displayed: "EXTERNAL TEMPERATURE SENSOR REQUIRED".
sIf "SATURATED STEAM DELTA HEAT" or "WATER DELTA HEAT" is selected, the HART INPUT field automatically
switches to "TEMPERATURE".
tOnly data for the gas phase are available for these fluids.
uThese functions are only called up if the OTHER option was selected in one of the functions GAS TYPE 1 to 8.
vThe entry only appears if  was selected in the GAS TYPE 1 to 8 function.

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 diameters 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 (å4). 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: Instructions for transporting sensors with DN 40 to 300 (1½ to 12")
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)
• Protect the measuring device against direct sunlight during storage in order to avoid unacceptably
high surface temperatures.

Proline Prowirl 73 Installation
Endress+Hauser 17
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 therefore have to be taken into account
(ä20).
• The maximum permitted ambient temperatures (ä84) and fluid temperatures (ä85)
must be observed.
• Pay particular attention to the notes on orientation and piping insulation (ä18).
• 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 
(ä140, D MATING PIPE function).
• 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 Dimensions
All the dimensions and lengths of the sensor and transmitter are provided in the separate "Technical
Information" document.
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 (A) in all directions = 100 mm (3.94")
• Necessary cable length (L): L + 150 mm (5.91")

3.2.4 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. 6: 1 = Flanged version, 2 = Wafer version
"Caution!
Danger of electronics overheating!
• Always keep the adapter between the sensor/transmitter and the connection housing of the
remote version free of insulating material.
• Note that a certain orientation might be required, depending on the fluid temperature (ä18).
• Observe information on the permissible temperature ranges (ä84).
mIn the case of liquids, there should be upward flow in vertical pipes to avoid partial pipe filling (Fig. A).
"Caution!
Disruption in flow measurement!
To guarantee the flow measurement of liquids, the measuring tube must always be completely full in pipes with
vertical downward flow.
n"Caution!
Danger of electronics overheating!
If fluid temperature is 200 °C (392 °F), orientation B is not permitted for the wafer version (Prowirl 73W) with
nominal diameters DN 100 (4") and DN 150 (6").
In order to ensure that the maximum permissible ambient temperature for the transmitter is not exceeded (ä84), we
recommend the following orientations:
oIn the case of hot fluids (e.g. steam or fluid temperature (TM) 200 °C (392 °F)): orientation C or D
pIn the case of very cold fluids (e.g. liquid nitrogen): orientation B or D
