2 Safety
2.1 Intended use
The flow meter described in this Operating Instructions is intended to measure mass flow
of fluids and gases while simultaneously also capturing their density and temperature.
These values form the basis for calculating additional measured quantities, such as
volume flow and concentration of fluids.
The flow meter uses the Coriolis principle and can be used in process automation for a
wide range of flow rate measurements. It allows for measuring various fluids, e.g.:
▪ Oils, grease
▪ Gases, liquid gases
▪ Acids, solutions, solvents
▪ Emulsions and suspensions
Use of the flow meter is limited primarily by the necessary homogeneity of the fluid and
chemical resistance of the wetted parts. Details can be obtained from the responsible
Siemens sales organization. Operational safety cannot be ensured in the event of any
improper or not intended use. Siemens is not liable for damage arising from such use.
The flow meter described in this Operating Instructions is a class A device according to
EN 61326-1 and may only be used in an industrial environment.
2.2 Technical conditions
At normal conditions, the flow meter does not release any poisonous gases or
substances.
If the flow meter is operated in faulty conditions, its safety and function may be impaired.
For this reason, the following must be observed:
▶Operate the flow meter only when in good working order.
▶If its operational performance changes unexpectedly, check flow meter for faults.
▶Do not undertake unauthorized conversions or modifications on the flow meter.
▶Eliminate faults immediately.
▶Use only original spare parts.
2.3 General safety instructions
DANGER Use of fluids that are a health hazard may result in caustic burns or
poisoning
▶When removing the flow meter, avoid touching the fluid and breathing gas residues
left in the sensor.
▶Wear protective clothing and a breathing mask.

General safety instructions
FC6x0
Safety
A5E52748375-AA, 2023/09 11 / 194
DANGER Use of unproper materials through the customer may result in heavy
corrosion and/or erosion
▶The medium temperature / pressure ranges are calculated and approved without
corrosion or erosion.
▶The customer is fully responsible to select proper materials to withstand his corrosive
or erosive conditions.
▶In case of heavy corrosion and/or erosion the instrument may not withstand the
pressure and an incident may happen with human and / or environmental harm.
▶Siemens will not take any liability regarding damage caused by corrosion / erosion.
▶If corrosion / erosion may happen, the user has to check periodically if the necessary
wall thickness is still in place.
DANGER Improper installation in hazardous area
The following basic safety instructions must be observed when handling the flow meter:
▶When using the flow meter in areas at risk of explosion, compliance with the
Explosion Proof Type Manual is mandatory.
WARNING High fluid temperatures may result in hot surfaces and therefore a risk of
burns
▶Apply thermal insulation to sensor.
▶Attach warning labels to the sensor.
▶Wear protective gloves.
WARNING Risk of injury from electrical shock due to inadequate clothing
▶Wear protective clothing as required by regulations.
WARNING Risk of injury from electrical shock at the transmitter
▶Avoid handling the transmitter with wet hands.
▶Wear protective gloves.
The following basic safety instructions must be observed when handling the flow meter:
▶Carefully read the Reference Manual prior to operating the flow meter.
▶Only qualified specialist personnel must be charged with the tasks described in this
Operating Instructions.
▶Ensure that personnel complies with locally applicable regulations and rules for
working safely.
▶Do not remove or cover safety markings and nameplates from flow meter.
▶Replace soiled or damaged safety markings on the flow meter. For replacing please
contact the Siemens Service Center.
▶If SITRANS FC is used to measure safety-related quantities, ensure that the
transmitter does not display any error messages and, if applicable, the Total Health
Check function is performed at regular intervals.
▶Avoid erosion and corrosion as they reduce accuracy and resistance to temperature
and pressure. Over time, calibration constants change as a result of erosion and
corrosion, therefore requiring recalibration. Siemens does not assume any guaranty
or liability with respect to corrosion resistance of wetted parts in any specific process.
The user is responsible for selecting the appropriate materials. Siemens provides
support in clearing up the question of corrosion resistance of the materials used
(special fluids but also cleaning agents). Minor changes in temperature, concentration
or pollution degree in the process may result in differences in terms of corrosion

Safety General safety instructions

resistance. In case of corrosion or erosion, the pipes must be checked periodically to
ensure necessary wall thickness. This can be accomplished by using, for example,
the Tube Health Check function.
▶When performing welding tasks on the pipe, it is important not to ground the welding
equipment by way of the flow meter. Soldering and welding work on parts of the flow
meter is prohibited.
▶Continuous temperature fluctuations in excess of 100 °C may result in tube failure
due to material fatigue and therefore must be avoided.
▶The operator is responsible for ensuring that design limits (pressure, temperature) are
not exceeded in the event unstable fluids decay.
▶External influences may result in failure of threaded connections. The operator is
responsible for providing suitable protective measures.
▶Compression and shock waves in pipes can cause damage to the sensor. For this
reason it is important to avoid exceeding the design limits (pressure, temperature).
▶Fires may result in increased process pressure (caused by temperature-related
volume changes) and failure of gaskets. The operator is responsible for taking
suitable measures to prevent fire-related damage.
▶Manufacturing methods and technologies have been successfully field-tested for
decades. Erosion and/or corrosion are not taken into account.
▶Removal of material from the flow meter with power tools such as drills or saws is not
permitted.
▶Any repair, modification, replacement or installation of replacement parts is permitted
only if it's complying with this Operating Instructions. Other work must be first
authorized by Siemens. Siemens does not assume liability for damage caused by
unauthorized work on the flow meter or by improper use.

5 Transport and storage
5.1 Transport
The following rules apply when transporting the flow meter:
▶Observe the transport-related instructions on packaging.
▶In order to avoid damage, do not unpack the flow meter until it is at the installation
site.
▶Do not remove protective materials, such as protective stickers or covers from
process connections during transport.
▶Starting at a weight of 15 kg, have at least two persons and/or use suitable tools
(shoulder straps, lifting device, cart) to lift and transport the flow meter.
WARNING Risk of injury from slipping or falling flow meter
▶Ensure that suspension points of the ropes are located above the flow meter's center
of gravity.
▶Use a lifting device meeting local regulations.
▶Attach lifting ropes to process connections.
▶Do not suspend flow meter from transmitter housing, neck of sensor or flange holes.
The lifting ropes must always be attached to the sensor at the process connections
(except for the SITRANS FC1x0). The depictions that are crossed out in the figure below
show impermissible attachment types. This applies to the remote type, the remote type
with long neck and the compact type, independent of the design. If the process
connections are others than flanges, the holding ropes must be secured against slipping,
if necessary (for example, for the SITRANS FC5x0).

crossed out)
