Installing/mounting
Location in the system
The optimum location in the system depends on the application:
●Liquid applications
Gas or vapor bubbles in the fluid may result in erroneous measurements, particularly in the density measurement.
–Do not install the flowmeter at the highest point in the system, where bubbles will be trapped.
–Install the flowmeter in low pipeline sections, at the bottom of a U-section in the pipeline.
Figure 3-1 Liquid applications, wrong location with trapped air/gas
●Gas applications
Vapor condensation or oil traces in the gas may result in erroneous measurements.
–Do not install the flowmeter at the lowest point of the system.
–Install a filter.
Figure 3-2 Gas applications, wrong location with trapped oil
Flow direction
The calibrated flow direction is indicated by the arrow on the sensor. Flow in this direction will be indicated as positive by
default. The sensitivity and the accuracy of the sensor do not change with reverse flow.
The indicated flow direction (positive/negative) is configurable.

CAUTION
Accurate measurement
The sensor must always be completely filled with process media in order to measure accurately.
Orienting the sensor
The sensor operates in any orientation. The optimal orientation depends on the process fluid and the process conditions.
Siemens recommends orienting the sensor in one of the following ways:
1. Vertical installation with an upwards flow (self-draining)
Figure 3-3 Vertical orientation, upwards flow
2. Horizontal installation, tubes down (recommended for liquid applications)
Figure 3-4 Horizontal orientation, tubes down
3. Horizontal installation, tubes up (recommended for gas applications)
Figure 3-5 Horizontal orientation; tubes up

Note
Hygienic applications
In 3A and EHEDG certified hygienic applications the flowmeter must be installed vertically as shown in 1 above.
Installation in a drop line
Installation in a drop line is only recommended if a pipeline reduction or orifice with a smaller cross-section can be installed
to create back-pressure and prevent the sensor from being partially drained while measuring.

Mounting the device
NOTICE
Incorrect mounting
The device can be damaged, destroyed or its functionality impaired through improper mounting.
●Before installing ensure there is no visible damage present on the device.
●Make sure that process connectors are clean, and suitable gaskets and glands are used.
●Mount the device using suitable tools.
WARNING
Unsuitable connecting parts
Danger of injury or poisoning.
In case of improper mounting hot, toxic and corrosive process media could be released at the connections.
●Ensure that connecting parts (such as flange gaskets and bolts) are suitable for connection and process media.
●Install the sensor in well-supported pipelines in order to support the weight of the flowmeter.
●Center the connecting pipelines axially in order to assure a stress-free installation. The flowmeter must not be used to
bring the rest of the pipework into line; make sure the pipework is correctly aligned before inserting the flow sensor.

A5E33120231-001, 12/2013 5
●Install two supports or hangers symmetrically and stress-free on the pipeline in close proximity to the process
connections.
Note
Handling
Never lift the flowmeter using the housing, that is always lift the sensor body.
Avoid vibrations
●Make sure that any valves or pumps upstream of the sensor do not cavitate and do not send vibrations into the sensor.
●Decouple vibrating pipeline from the flow sensor using flexible tube or couplings.
Figure 3-7 Non-flexible pipes not recommended in vibrating environment
Figure 3-8 Flexible pipes recommended in vibrating environment
Avoid cross talk
If operating more than one flowmeter in one or multiple interconnected pipelines there is a risk of cross talk.
Prevent cross talk in one of the following ways:
●Mount sensors on separate frames
●Decouple the pipeline using flexible tube or couplings
Figure 3-9 High risk of cross talk when using non-flexible pipes
Figure 3-10 Low risk of cross talk when using flexible pipes and separate frames

Connecting
Note
End Of Line (EOL) termination
The FC410 EOL termination DIP switch is default set to EOL active. To change termination setting see Setting the EOL
termination DIP switches (Page 8).
M12 version
The sensor is provided with a preformed cable terminated with M12 style stainless steel weather-proof plugs.
The cable screen is physically and electrically terminated within the body of the plug.
Take care when handling the cable and passing it through cable ducting that the plug is not subjected to excessive tension
(pulling) as the internal connections may be disengaged.
Note
Never pull the cable by the plug - only by the cable itself.
1. Connect the sensor using the supplied 4-wire cable with M12 connectors.
Note
Grounding
The sensor cable screen is mechanically connected to the grounding terminal (PE), only when the M12 plug is correctly
tightened.

lid by one quarter of a turn to seal on the O-ring.
8. Reinstate and tighten the lid lock screw.
Setting the EOL termination DIP switches
It is important to terminate the Modbus RS 485 line correctly at the start and end of the bus segment since impedance
mismatch results in reflections on the line which can cause faulty communication transmission.
If the device is at the end of the bus segment, it is recommended to terminate the device as shown in Auto hotspot. The
table below shows the relation between the DIP switch settings and the permissible communication interface set-ups.
Default configuration is EOL active.
Location of DIP switch
The DIP switch is located in the electronic as shown below.
