3.1 System configuration
Generally after deciding on the necessary flow measurements an evaluation should be done.
In this way, the best economical solution can be obtained since configurations and accuracy
measurement requirements can be in conflict with the overall system costs. In particular
when using Clamp-on systems it’s important to perform a very detailed evaluation. Later this
will result in smooth installations and the highest customer satisfaction.
For example, a poor accuracy may result if the installed pipe size is different than actual pipe
size. Although operation may still be achieved, accuracy can be compromised due to
incorrect volume calculation.
The SITRANS F US ultrasonic flowmeter systems consist of a transmitter, one or two sensor
pairs and the connecting cables. The following table lists process temperatures for the
available combinations of sensors and transmitters.

SITRANS F flowmeters with minimum IP66/IP67/NEMA 4X enclosure rating are suitable for
indoor and outdoor installations.
If applicable, make sure that specifications for rated medium temperature (TS) plus ambient
temperature that are indicated on the device nameplate / label will not be exceeded.
Ensure that the device is suitable for the application and that it is installed where there is no
risk of penetration of aggressive vapors.

4.2 Installation safety precautions
Prevent the device from overheating or materials becoming brittle due to UV exposure by
protecting it from direct sunlight. Make sure that the maximum permissible ambient
temperature is not exceeded. Refer to the information in Technical data (Page 81).
Risk of explosion in hazardous areas
Special requirements apply to the location and installation of the device. See Installation in
hazardous areas (Page 15).
Special precautions must be taken when the flowmeter is mounted in applications with
working pressures/media that can be dangerous to people, surroundings, equipment or
others in case of pipe fracture.
● Take appropriate protective measures to avoid contact with surfaces with temperatures
above 70 °C (155 °F).
● Prevent severe external stresses and loads from acting on the device.
● Do not install the flowmeter in the vicinity of strong electromagnetic fields, for example
near motors, variable frequency drives, transformers etc.

Mounting location transmitter/sensors, distance and required
There are a number of factors to consider when deciding on an installation location for the
clamp-on sensors and transmitter. Primarily, the pipe section should remain completely full
during normal operation and be in reasonable condition, without excessive corrosion (or
scaling) which can interfere with ultrasound transmission into the fluid. Available straight pipe
run and installation in hazardous areas are also important points to consider when selecting
a location.
The following hardware characteristics need to be considered:
●
maximum allowed sensor cable length. (Refer to appropriate transmitter Operating

●
material and dimensions.

Selecting a location for the sensors
4.4 Determining a location
● Avoid, if possible, the following installations:
– Installation at the highest point of the pipe system
– Installation in vertical pipes with free outlet or downwards flow
1. Locate the sensors downstream from the center of the longest available straight run. A
location ten pipe diameters or greater downstream from the nearest bend will provide
adequate flow profile conditions.
2. Do not, if possible, install the sensors downstream from a throttling valve, a mixing tank,
the discharge of a positive displacement pump or any other equipment that could possibly
aerate the liquid. The best location will be as free as possible from flow disturbances,
vibration, sources of heat, noise, or radiated energy.
3. Avoid mounting the sensors on a section of pipe with any external scale. Remove all
scale, rust, loose paint, etc., from the location.
4. Do not mount the sensors on a surface aberration (pipe seam, etc.)

5. Do not mount sensors from different ultrasonic flowmeters on the same pipe. Also, do not
run the sensor cables in common bundles with cables from other instrumentation. You
can run these cables through a common conduit ONLY if they originate at the same
flowmeter.

a horizontal pipe is either the ten o’clock and two o’clock position for Reflect mode, or one
sensor at nine o’clock and one sensor at three o’clock for Direct Mode. Mounting on a
vertical pipe is recommended only if flow is in the upward direction. When mounting on a
vertical pipe flowing in a downward direction make sure there is sufficient back pressure
in the system to maintain a full pipe.

Refer to the transmitter Operating Instructions for transmitter mounting.
The transmitter independently calculates the best distance for the sensors on the pipe
according to the selected parameters. A manual search for the best signal strength and
signal quality is not necessary. To receive these calculations, certain parameters have to be
programmed into the meter:
● Pipe outer diameter (e.g. selection by inside table > metric DIN100 -> 114.3 mm)
● Pipe wall thickness (DIN automatically 3.6 mm or by manual input)
● Pipe material - Steel or other materials from material tables
● Liner inside - (e.g. Cement - 5 mm)
● Medium settings - Liquid Class (Water 20°C or other kind of liquid by table or custom
setting)
● Pipe Up- and Downstream conditions (only required if condition is not ideal)
● Sensor type - Sensor model (e.g. FSS200 Universal)

IMPORTANT
Avoid installing sensors on top or on the bottom of a horizantal pipe.
4.5 Orienting the sensors
There are no flow direction symbols shown in the sensors. Positive flow is defined as the
movement of fluid from the upstream "A" sensor to the downstream "B" sensor, whereas
negative flow is in the reverse direction.
Siemens recommends orienting the sensors in one of the following ways:
1. Vertical orientation with an upwards flow in order to minimize the effect of gas / air
bubbles in the media (sensors shown in Reflect Mount).
Figure 4-2 Vertical installation with an upwards flow
2. Horizontal orientation with sensors shown in Reflect Mount and Direct mount. Note that
flow can move in either direction.

To install the sensors these basic steps must be followed:
1. Program parameters into transmitter
2. Mount the sensors on pipe using parameters from transmitter
3. Connect sensor cables from sensor to transmitter
All though the transmitter recommends a mounting mode after analyzing your pipe and liquid
data entries you can still install clamp-on sensors in the way that best suits your application
and the sensor type you have purchased.

Figure 4-3 Reflect mount (Pipe shown from above in 12 o'clock position)
Reflect mount is recommended whenever possible. This is the simplest way to mount the
sensors. Also, Reflect mount resists abnormal flow profile conditions such as cross-flow
within the flow stream. In addition, Reflect mount may be the only possibility if conditions do
not allow access to the opposite side of the pipe.
Direct mount provides a shorter sonic beam path. This usually improves performance with
sonically attenuative liquids or pipe materials. Direct mount is recommended for plastic
pipes. Compared to Direct mounting, Reflect mount requires almost double the amount of
mounting length. Therefore, Direct mount may be the only option if the availability of
mounting space is limited.
