1.3
Preliminary Information
The following information is specifically for the FSS200 sensors.
Clamp-on ultrasonic flowmeters can accommodate a wide range of fluid flow applications.
These instructions expect that only a technically instructed person will be installing these
flowmeters. Knowledge about process conditions and application parameters are
prerequisite, including knowledge of the functional principles of these flowmeters.
Further information:
Siemens provides special training and other information via the Internet, including helpful
installation videos. Helpful links will be listed inside this manual separately.

1.5
Required Tools
It is helpful to have common electric and hand tools available for installation of the sensors.
●For easy programming, a PC would also be helpful and can be used later for diagnostics
and documentation.
●Sensor cables are normally preassembled at the transmitter end.
●Hot-air gun if shrink sleeves are needed.
●A plastic hammer and bubble level should be used for sensor mounting and Vernier
adjustment of sensor frames.
●For preparing irregular pipe surfaces that have old paint, corrosion, etc. an electric hand
sander may be used.
●An optional circumference tape measure for pipe and sensor installation.
Note
Important
Never use an electric hand grinder or angle grinder when preparing pipe surfaces.
Incorrect bevel and chamfer angles at the pipe surface can disturb clear signal transmission.
●Use a thickness gauge to measure pipe wall thickness. If not available use pipe class
tables or call technical support.
●Assorted sizes of screwdrivers, nut drivers and wrenches.

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit:
http://www.siemens.com/industrialsecurity
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.
