“SENSOR INSTALLATION” Quick Setup Page 64, 67
Measuring devices with a local display:
Use this “Quick Setup” ( → Page 64) to determine the data required for sensor installation
such as sensor distance (1), wire length, pipe materials, sound velocity in liquids, etc.
– The system provides you with the sensor distance for the W/P/U “clamp-on” versions as
distance data. For the W and P sensors, you also receive the data in the form of a letter for
sensor 1 and in the form of a number for sensor 2. You can thus easily position the sen-
sors with the aid of the mounting rail.
– With the butt-weld version, you receive the sensor distance as distance data.
Measuring devices without a local display:
No “Sensor Installation” Quick Setup is available for devices without a local display.
The sensor installation procedure for such devices is explained on
→ Page 67.
Connection of the sensor/transmitter connecting cable → Page 35

Commissioning via “QUICK SETUP”
Commissioning via “ToF Tool - Fieldtool Package”
Page 65, 67
Measuring devices with a local display:
You can commission your measuring device quickly and easily using the special “Quick
Setup” menu → Page 65. This means that important basic functions can be configured
directly via the local display, e.g. display language, measured variables, engineering units,
etc.
Where necessary, the following adjustments and configurations must be carried out
separately:
– Zero point adjustment
–Busaddress
–Tagname
– Configuration of the totalizers
Measuring devices without a local display:
– No “Commissioning” Quick Setup is available for devices without a local display.
The commissioning procedure for such devices is explained on → Page 67
A0001055
▼
Customer-specific configuration Page 45 ff.
Complex measurement tasks require the configuration of additional functions which you
can individually select, set and adapt to your process conditions using the function matrix.
There are two options:
– Setting parameters via the configuration program “ToF Tool - Fieldtool Package”
– Setting parameters via the local display (optional)
All functions are described in detail, as is the function matrix itself, in the “Description of
Device Functions” manual, which is a separate part of these Operating Instructions.

Proline Prosonic Flow 90 1 Safety instructions
Endress+Hauser 7
1 Safety instructions
1.1 Designated use
The measuring device described in these Operating Instructions is to be used only for measuring the
flow of liquids in closed pipes, e.g.:
• Ultra clean water with low conductivity
• Water, wastewater, etc.
As well as measuring the volume flow, the measuring system also always measures the sound
velocity of the fluid. The sound velocity can be used to distinguish different fluids or as a measure
of fluid quality.
The manufacturer accepts no liability for damage resulting from incorrect use or other than
designated use.
1.2 Installation, commissioning and operation
Note the following points:
• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorized to perform such work by the facil-
ity'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 plant operator.
Strict compliance with the instructions in the Operating Instructions is mandatory.
• Endress+Hauser will be happy to assist in clarifying the chemical resistance properties of parts
wetted by special fluids, including fluids used for cleaning.
• If welding work is performed on the piping system, do not ground the welding appliance through
the Prosonic flowmeter.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams. The transmitter must be grounded, unless the power supply is galvanically
isolated.
• Invariably, local regulations governing the opening and repair of electrical devices apply.
1.3 Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate “Ex docu-
mentation”, which is an integral part of these Operating Instructions. Strict compliance with the
installation instructions and connection data as listed in the supplementary “Ex” documentation
is mandatory. The symbol on the front of the Ex documentation indicates the approval and the
certification body (0Europe, 2 USA, 1 Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of EN 61326/A1, and NAMUR Recommendation NE 21.
• 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.

8Endress+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. 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
EN 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. flam-
mable, 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. They have been tested and
left the factory in a condition in which they are safe to operate. The devices comply with the appli-
cable standards and regulations in accordance with EN 61010 “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 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.

• 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
The devices must be transported in the container supplied when transporting them to the measuring
point.
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 storage temperature corresponds to the ambient temperature range (Page 99) of the
transmitter, the measuring sensors and the corresponding sensor cables.
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.

3.2 Installation conditions
3.2.1 Installation dimensions
The dimensions and the fitting lengths of the sensors and the transmitter are on Page 104 ff.
3.2.2 Installation location
Correct measuring is possible only if the pipe is full. Avoid the following installation locations:
• Do not install at the highest point in the run. Risk of air accumulating.
• Do not install directly upstream from an open pipe outlet in a down pipe.
A0001103
Fig. 5: Installation location
Down pipes
Notwithstanding the above, the installation proposal below permits installation in an open down
pipe. Pipe restrictions or the use of an orifice plate with a smaller cross-section than the nominal
diameter prevent the pipe from running empty while measurement is in progress.

3.2.3 Orientation
Vertical orientation
Recommended orientation with upward direction of flow (View A). Entrained solids sink down.
Gases rise away from the measuring sensor when fluid is not flowing. The piping can be completely
drained and protected against build-up.
Horizontal orientation
In the recommended installation range in a horizontal installation position (View B), gas and air
accumulation at the pipe cover and problematic build-ups at the bottom of the pipe have a minor
influence on the measurement.

3.2.4 Inlet and outlet runs (clamp-on version)
If possible, install the sensor well clear of assemblies such as valves, T-pieces, elbows, etc. If several
flow obstructions are installed, the longest inlet or outlet run must be considered. Compliance with
the following requirements for the inlet and outlet runs is recommended to ensure measuring accu-
racy.

3.2.7 Sensor arrangement (clamp-on)
The transmitter offers a number of options between 1 and 4 traverses for the type of installation.
Please note that the signal strength is reduced with each additional reflection point in the pipe.
(Example: 2 traverses = 1 reflection point)
To achieve the best signal quality possible, choose the least number of traverses required for a
sufficient transit time difference.
A0001108

1 = 1 traverse, 2 = 2 traverses, 4 = 4 traverses
Recommendations:
Due to their design and properties, the Prosonic Flow sensors are particularly suited to certain
nominal diameter ranges and pipe wall thicknesses. For this reason, various sensor types W, P and
U are offered for these different applications.
Recommendations for sensor installation can be found in the following table.
* see note below
!Note!
• The installation of clamp-on sensors is principally recommended in the 2 traverse type of instal-
lation. This type of installation allows the easiest and most comfortable type of mounting and
means that a system can also be mounted even if the pipe can only be accessed from one side.
• If the pipe nominal diameter is small (DN 60 and smaller), the sensor spacing with Prosonic
Flow W/P can be too small for an installation with 2 traverses. In this case, the 4 traverse type of
installation must be used. In all other instances, the 2 traverse configuration is the preferred
method.
• The use of Prosonic Flow W/P sensors DN 100...4000 is principally recommended for pipes with
a wall thickness >4 mm, pipes made of composites such as GRP, pipes with lining and for
applications with media with high acoustic damping, even for nominal diameters < DN 100.
For these applications, we principally recommend mounting the W/P sensors with 1 traverse
configuration.
• In the DN 15...50 nominal diameter range, Prosonic Flow U is preferred for use on plastic pipes.
Both the Prosonic Flow W/P and the Prosonic Flow U sensor types can be used in the
DN 50...100 nominal diameter range. The use of Prosonic Flow W/P sensors is principally
recommended for applications as of DN 60.
• If the measuring device displays an insufficient signal strength, reduce the number of the
traverses.

3.3 Installation instructions
3.3.1 Installing tensioning bands (clamp-on)
For W/P sensors DN 50...200
1. Push one of the supplied threaded bolts on the tensioning band.
2. Run the tensioning band around the pipe without twisting it and push the end through the
tensioning band lock (make sure that the screw is pushed up).
3. By hand, make the tensioning band as tight as possible.
4. Push the screw down and tighten the tensioning band with a screwdriver so that it cannot slip.
5. If so desired, shorten the tensioning band to the desired length.
"Caution!
Risk of injury. When shortening the tensioning band, try to avoid sharp edges.
A0001109
Fig. 11: Tensioning band installation for DN 50...200
For W/P sensors DN 250...4000
The following steps relate to Fig. 12 on Page 19.
1. Measure the pipe circumference.
Shorten the tensioning band to the pipe circumference +10 cm.
"Caution!
Risk of injury. When shortening the tensioning band, try to avoid sharp edges.
2. Loop the tensioning band through one of the centering plates supplied with the threaded
bolt (1).
3. Insert both ends of the tensioning bands down into the openings in the tensioning band lock
(2). Bend back the ends of the tensioning bands.
4. Interlock both halves of the lock (3). Make sure that there is sufficient space for the tensioning
band to be tightened with the locking screw.
5. Tighten the tensioning band using a screwdriver (4).

3.3.2 Use of weld bolts for W/P sensors
Weld studs can be used instead of tensioning bands for the following types of installation of the
W/P clamp-on measuring sensors.
!Note!
To determine the sensor distance (distance from the centre of the first stud to the centre of the
second bolt) use:
• the “Sensor Installation” Quick Setup menu if the measuring device has a local operation. Use the
Quick Setup as described on Page 64. The sensor distance is displayed in the SENSOR DISTANCE
function. The transmitter has to be installed and connected to the power supply to carry out the
“Sensor Installation” Quick Setup.
• the procedure described on Page 67 ff. if the measuring device has no local operation.
For an exact description of the sensor installation process, please refer to the appropriate pages of
the clamp-on versions. You must keep to same installation sequence.
If you want to use a non-metric M6 ISO thread, please note the following:
• You require a sensor holder with a removable locking nut.
(Ordering code: 90WAx – xBxxxxxxxxxx)
• Remove the preinstalled locking nut on the sensor holder with a metric ISO thread.
• Use a nut which matches your threaded bolt.
