“SENSOR INSTALLATION” Quick Setup Page 76
Measuring devices with a local display:
Use this “Quick Setup” (→ Page 76) 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 sensors 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 84.

Commissioning via “QUICK SETUP”
Commissioning via FieldTool
Page 78, 84
Measuring devices with a local display:
You can commission your measuring device quickly and easily using the special
“Quick Setup” menu → Page 78. 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
– Bus address
– Tag name
– 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 84
▼
Application-specific QUICK SETUPs Page 80 ff.
In “Quick Setup” mode, you have the option of starting other, application-spe-
cific Quick Setups, for instance the menu for measuring pulsating flow.
▼
Customer-specific configuration Page 57 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 FieldTool
– 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 93 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 fluids in closed pipes, e.g.:
•Acids, alkalis, paints, oils
•Liquid gas
•Ultrapure water with low conductivity, water, wastewater
In addition to the volume flow, the system measures the sound velocity in the fluid. The
sound velocity can be used to distinguish different fluids or as a measure of fluid quality.
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, 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 facility's owner-operator. The specialist must have read and under-
stood these Operating Instructions and must follow the instructions they contain.
•The device must be operated by persons authorized and trained by the plant opera-
tor. Strict compliance with the instructions in the Operating Instructions is mandatory.
•Endress+Hauser will be happy to assist in clarifying the chemical resistance proper-
ties 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 appli-
ance 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 documentation”, which is an integral part of these Operating Instructions. Strict
compliance with the installation instructions and connection data as listed in the sup-
plementary “Ex” documentation is mandatory. The symbol on the front of the Ex doc-
umentation indicates the approval and the certification body
(0 Europe, 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 Recommenda-
tion NE 21 and NE 43.
•The manufacturer reserves the right to modify technical data without prior notice. Your
E+H distributor will supply you with current information and updates to these Operat-
ing Instructions.

1.4 Return
The following procedures must be carried out before a flowmeter requiring repair or cal-
ibration, 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 hazard-
ous 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 haz-
ardous 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 applicable 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 incor-
rectly 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.

3.1 Incoming acceptance, transport and storage
3.1.1 Incoming acceptance
•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 125)
of the transmitter, the measuring sensors and the corresponding sensor cables.
•The measuring device must be protected ageinst 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 130 ff.
3.2.2 Installation location
Correct measuring is possible only if the pipe is full. Avoid the following installation loca-
tions:
•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.
Fig. 4: 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-sec-
tion 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 con-
sidered. Compliance with the following requirements for the inlet and outlet runs is rec-
ommended to ensure measuring accuracy:

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 reflec-
tion 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.
Fig. 9: Sensor arrangement (Clamp On)
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 are offered for Prosonic Flow W, P and U 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 installation. 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, even for nominal diameters < DN 100. This applies also to applications with
media with high acoustic damping. 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 Two-channel measuring devices
PROline Prosonic Flow 93 has two measuring channels which are independent of one
another. In other words, the transmitter supports the simultaneous operation of two sen-
sor pairs at two individual measuring channels. In doing so, the resources of the trans-
mitter are split evenly between the two channels.
This ability of the transmitter can be used in many different ways:
•For two-channel measurement
•For two-path measurement
The transmitter can output the measured values of both channels either individually or
arithmetically linked (as total, difference or mean).
3.3.1 Two-channel measurement
In the case of dual-channel measurement, the measured values of two independent
measuring points are determined and processed by one transmitter.
Abb. 10: Two-channel measurement
a Cable for power supply
b Signal cable (Outputs)
If required, the measured values of measuring channel 1 and measuring channel 2 can
be arithmetically linked together. The following possibilities for outputting measured val-
ues are suitable for dual-channel measurement:
•Individual output of measured values from channel 1 and 2
•Total of measured values from channel 1 and 2
•Difference of measured values from channel 1 and 2
The measuring device supports the individual configuration of the measuring channels
and the independent setting of the display and outputs. As a result, the sensor type and
type of installation, for example, can be selected and configured separately for both
channels.

!Note!
•The necessary settings for measured value output for two-channel measurement can
be found under the appropriate ASSIGN function for the display, outputs and totalizers
(see Description of Device Functions Prosonic Flow 93, BA071D/06/en/).
•The current measured values linked arithmetically can be found in the CALCUL. MAIN
VALUES function group (see Description of Device Functions Prosonic Flow 93,
BA071D/06/en/).
•The settings for the measuring channels are made independently for channel 1 and
channel 2 in the PROC. PARAM. (CH1...CH2), SYS. PARAM. (CH1...CH2) and SEN-
SOR DATA (CH1...CH2) function groups.
•Please pay special attention to the installation recommendations in Chapter “Installa-
tion location”, Page 14, Chapter “Orientation”, Page 15, Chapter “Inlet and outlet runs
(Clamp On version)”, Page 15 as well as the recommendations on the type of instal-
lation in Chapter “Sensor arrangement (Clamp On)”, Page 17.
3.3.2 Two-path measurement
In dual-path measurement, the transmitter is used to operate two sensor pairs which are
installed on the same pipe. Different applications can necessitate different types of
installation.

The following possibilities for outputting measured values are suitable for dual-path
measurement:
•Individual output of measured values from channel 1 and 2
•Arithmetic mean of the measured values from channel 1 and 2 (CH1 + CH2 / 2)
The possibility of obtaining the mean value in dual-path measurement provides the
advantage of a more stable measured value. A measured value that is generated from
two independent measuring signals is generally less sensitive to irregularities and faults
in the application.
As a result, if conditions are not ideal, for example, the dual-path system means that the
different flow components within the flow can be better determined thanks to the fact
that the measured values are determined independently on two levels. Differences are
then balanced out when the two measured values are subsequently averaged to form
one process variable. This often results in a more stable and more accurate measured
value than would be the case with single-path measurement.
The measuring device supports the individual configuration of the measuring channels.

•The necessary settings for measured value output for two-path measurement can be
found under the appropriate ASSIGN function for the display, outputs and totalizers
(see Description of Device Functions Prosonic Flow 93, BA071D/06/en/).
•The current measured values linked arithmetically can be found in the CALCUL. MAIN
VALUES function group (see Description of Device Functions Prosonic Flow 93,

•The settings for the measuring channels are made independently for channel 1 and
channel 2 in the PROC. PARAM. (CH1...CH2), SYS. PARAM. (CH1...CH2) and SEN-
SOR DATA (CH1...CH2) function groups. In general, identical setting values are rec-
ommended for both channels in dual-path measurement. The independent setting for
channel 1 and 2 makes it possible, however, to balance out application-specific asym-
metry.

tion location”, Page 14, Chapter “Orientation”, Page 15, Chapter “Inlet and outlet runs
