Introduction
1.6 Security information
SITRANS FM MAG 3100
6Operating Instructions, 12/2021, A5E03005599-AE

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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected to
an enterprise network or the internet if and to the extent such a connection is necessary and only
when appropriate security measures (e.g. 󹪝rewalls and/or network segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends that product updates are applied as soon as they are available
and that the latest product versions are used. Use of product versions that are no longer
supported, and failure to apply the latest updates may increase customer’s exposure to cyber
threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed
under
https://www.siemens.com/industrialsecurity.
1.7 Transportation and storage
To guarantee su󹪟cient protection during transport and storage, observe the following:
• Keep the original packaging for subsequent transportation.
• Devices/replacement parts should be returned in their original packaging.
• If the original packaging is no longer available, ensure that all shipments are properly
packaged to provide su󹪟cient protection during transport. Siemens cannot assume liability
for any costs associated with transportation damages.
NOTICE
Insu󹪟cient protection during storage
The packaging only provides limited protection against moisture and in󹪝ltration.
• Provide additional packaging as necessary.
Special conditions for storage and transportation of the device are listed in Technical
speci󹪝cations (Page 73).
1.8 Notes on warranty
The contents of this manual shall not become part of or modify any prior or existing agreement,
commitment or legal relationship. The sales contract contains all obligations on the part of
Siemens as well as the complete and solely applicable warranty conditions. Any statements
regarding device versions described in the manual do not create new warranties or modify the
existing warranty.

Note
Compact mounted versions
For intrinsically safe data for MAG 3100 Ex compact mounted with MAG 6000 I Ex d, refer to the
Operating Instructions of MAG 6000 I or to certi󹪝cate number Sira 11ATEX2124X, available
here: Certi󹪝cates (http://www.siemens.com/processinstrumentation/certi󹪝cates).
WARNING
With intrinsically safe circuits
If a non-conforming supply unit is used, the "fail-safe" type of protection will no longer be
e󹪜ective and the approval certi󹪝cation will be invalid.
With intrinsically safe circuits, use only certi󹪝ed meters appropriate for the transmitter.

Special conditions for safe use
It is required that:
• Electrical connections are in accordance with national requirements.
• Appropriate cable connectors are used for the output circuits:
– Intrinsically safe: blue
– Non-intrinsically safe: black
• Minimum 4 mm2 cable is to be used for potential equalization
• Cable glands for coil circuit must be Ex e approved (increased safety) and 󹪝t the application
by being approved for the cable used as regards size and temperature.

• Sensor insulation thickness is max. 100mm (only insulated sensors).
• IEC/EN 61241-14 and 61241-17 are considered for installation in areas with combustible
dust.
DANGER
Risk of explosion
Do NOT open the device while energized; otherwise there is a risk of explosion.
WARNING
Explosive gas or dust
The terminal box shall not be opened when an explosive gas or dust atmosphere may be
present.
WARNING
Potential equalization
In operation, the output is earthed through the conductive medium being measured and
therefore potential equalization is necessary throughout the hazardous area.
The apparatus housing shall be connected to the potential equalizing conductor in the
hazardous area.
WARNING
External connections to Ex e terminals
The external connections to the Ex 'e' Terminals of the Remote version shall comply with the
following:
• The wire conductors shall have a cross-sectional area between 0.5 mm2 and 2.5 mm2.
• No more than one single or multiple strand wire conductor shall normally be connected
to each of the terminals. If multiple conductors are required, these shall be joined in a
suitable manner, for example two conductors into a single insulated crimped boot lace
ferrule.
• The insulation on the wire conductors shall extend to within 1 mm of the metal of the
terminal throat.
• The terminal screws shall be tightened down with a torque between 0.5 Nm and 0.7 Nm.
• The terminals shall never be exposed to temperatures outside of the range -50°C to +
130°C; in addition, they shall only be installed and wired with cable in an ambient
temperature of -10 to +80°C. Furthermore, in the event of there being a process
temperatures of + 180°C in conjunction with an upper ambient temperature of +50°C
the terminal strips should not be installed or wired with cable.

WARNING
Laying of cables
Cable for use in zone 1 and 2 or 21 and 22 must satisfy the requirements for having a proof
voltage < AC 500 V applied between the conductor/ground, conductor/shield and shield/
ground.
Connect the devices that are operated in hazardous areas as per the stipulations applicable
in the country of operation, for example for Ex "d" and "nA", permanent cables must be laid.

Description 3
The main applications of the SITRANS F M electromagnetic 󹪞ow sensors can be found in the
following 󹪝elds:
• Process industry
• Chemical industry
• Steel industry
• Mining
• Utility
• Power generation & distribution
• Oil & gas / HPI
• Water & waste water
• Pulp & paper
3.1 System components
The SITRANS FM 󹪞owmeter system includes:
• Transmitter (types: SITRANS FM MAG 5000/6000 or MAG 6000 I)
• Sensor (types: SITRANS FM MAG 1100/1100 F, MAG 3100/3100 P or MAG 5100 W)

3.2 Design
SITRANS F M MAG 3100 is available in a wide range of sizes (DN 15 to DN 2000 (½" to 78")) and
pressure ratings (PN 6 to PN 100 / ANSI Class 150 / 300 / 600, AS 2129 / AS 4087 - on request up
to 690 bar (10 000 psi)). The fully welded construction provides a ruggedness that suits the
toughest applications and environments.
Sensor housing and 󹪞anges are designed in carbon steel (ASTM A 105) and terminal box in 󹪝bre
glass reinforced polyamide or optionally in stainless steel (AISI 316). Measuring pipe is made of
stainless steel (AISI 304) while liners and electrodes are available in various material, which
makes the sensor highly resistant to a wide range of chemicals.
The present range of liner types includes:
• PTFE
• PFA
• Soft rubber
• EPDM
• Linatex
• Ebonite Hard Rubber
Electrodes are available in:
• Hastelloy C276 or C22
• AISI 316Ti (1.4571)
• Platinum / Iridium
• Titanium
• Tantalum
The sensors carry a wide range of approvals, see Technical data (Page 73).
Inspection
1. Check for mechanical damage due to possible improper handling during shipment. All claims
for damage are to be made promptly to the shipper.
2. Make sure the scope of delivery, and the information on the nameplate corresponds to the
ordering information.
