Siemens Flow Instruments SITRANS F M electromagnetic flowmeters consist of a sensor and a
transmitter. These instructions only describe the sensor installation. For further information on the
transmitter installation, please refer to the SITRANS F M handbook.
Technical Documentation (handbooks, instructions, manuals etc.) on the complete product
range SITRANS F can be found on the internet/intranet on the following links:
Sensor MAG 1100 DN2...10 (1/12”...3/8") with adaptors
The MAG 1100 DN 2, 3, 6 and DN 10 are prepared for G ½" (ISO) or ½" NPT pipe connection.
The length "L" varies dependent on the gasket choice.

Installation, general
Reading and operating the flowmeter is possible under almost any installation conditions
because the display can be oriented in relation
to the sensor. To ensure optimum flow measurement attention should be paid to the following:
The sensor must always be completely full
with liquid.
Therefore avoid:
• Installation at the highest point in the pipe
system
• Installation in vertical pipes with free outlet
For partially filled pipes or pipes with downward flow and free outlet the flowmeter should
be located in a U-tube.
Installation in vertical pipes
Recommended flow direction: upwards. This
minimizes the effect on the measurement of
any gas/air bubbles in the liquid.

Installation, general
(continued)
Installation in horizontal pipes
The sensor must be mounted as shown in the
upper figure. Do not mount the sensor as
shown in the lower figure. This will position the
electrodes at the top where there is possibility
for air bubbles and at the bottom where there
is possibility for mud, sludge, sand etc.
If using empty pipe detection the sensor can be
tilted 45°, as shown in the upper figure.
Measuring abrasive liquids and liquids containing particles
Recommended installation is in a vertical/
inclined pipe to minimize the wear and deposits in the sensor.
Avoid vibrations!
Inlet and outlet conditions
To achieve accurate flow measurement it is
essential to have straight lengths of inlet and
outlet pipes and a certain distance between
pumps and valves.
It is also important to centre the flowmeter in
relation to pipe flanges and gaskets.
Installation in large pipes
The flowmeter can be installed between two
reducers (e.g. DIN 28545). Assuming that at 8°
the following pressure drop curve applies. The
curves are applicable to water.
Example:
A flow velocity of 3 m/s (V) in a sensor with a
diameter reduction from DN 100 to DN 80
= 0.8) gives a pressure drop of 2.9 mbar.

Potential equalization
To obtain optimum results from the measuring system the sensor’s chassis point/housing must
have the same electrical potential as the liquid being measured.
Depending on the type of gasket selected (graphite, EPDM or PTFE) and application, this can
be achieved as follows:
Graphite gasketsEPDM or PTFE gaskets
Electrically
conductive
piping
A: Potential equalization with electri-
cally conductive graphite gaskets
Electrically
non-conductive
piping
B: Potential equalization using earth
strap supplied.
C: Potential equalization with electri-
cally conductive graphite gaskets
D: Potential equalization using sepa-
rate potential equalization ring
The sensors DN 2, 3, 6 and DN 10 can also be mounted between two adapter flanges. In this
way the potential equalization with the liquid occurs automatically.
NOTE:
Special attention must be paid to piping systems with cathodic protection.
See SITRANS F M handbook.
For applications where high accuracy is
required, it will be advantageous to use
recessed flanges as shown in the drawing.
NB
To obtain optimum measuring accuracy and
the necessary tightness, it is important that the
sensor gaskets and the flange centre lines are
merging and that the connection flanges have
been mounted at right angles to the pipe.
The connection flanges must be parallel.

Installation
Tightening
The design of the sensor MAG 1100 allows for
bi-directional flow. Dimension L is given in the
previous table.
The arrow at the sensor indicates recommended
flow direction (the meter has been calibrated
with flow in arrow direction "+").

4. Gaskets
L. Sensor length incl. gaskets
First place three stay-bolts to locate the sensor, see a. These should be tightened gently, making
sure that each gasket fits exactly into its recess at either end of the sensor, see b.
The remaining flange bolts can now be inserted and tightened using about 25% of the actual
tightening torque, see table d.

The bolts must be tightened using up to 50% of the max.
tightening torque for the pipe dimensions stated. The max.
tightening torque for different size pipes is given in the table d.
The bolts must now be cross-tightened in the sequence shown
in c, using up to 100% torque.
1. Mount the cover or the transmitter on the
terminal box.
2. It is important that the screws are firmly
tightened (4 Nm). Use a large screwdriver
fitting into the screw slot.

Manufacturer’s design
and safety statement
1. Responsibility for the choice of lining and electrode materials with regard to their abrasion
and corrosion resistance lies with the purchaser; the effect of any change in process medium
during the operating life of the flowmeter should be taken into account. Incorrect selection
of lining and/or electrode materials could lead to a failure of the flowmeter.
2. It is the responsibility of the user to ensure that stresses and loading caused by earthquakes,
traffic, high winds and fire damage are taken into account during installation, when appropriate. These forces are not taken into account during flowmeter design.
3. It is the responsibility of the user to ensure that the flowmeter is installed such that it does not
act as a focus for pipeline stresses. External loadings are not taken into account during
flowmeter design.
4. During operation do not exceed the pressure and/or temperature ratings indicated on the data
label or in the installation instructions.
5. It is the responsibility of the user to ensure that all installations include over pressure protection,
means for draining/venting, and that adequate protection is provided to minimise
any risk of contact with hot surfaces.
6. Under the Pressure Equipment Directive this product is a pressure accessory, and not
approved for use as a safety accessory, as defined by the Pressure Equipment Directive.
7. Removal of the terminal box except by Siemens Flow Instruments or their approved agents
will invalidate the PED conformity of the product.
In accordance with the Pressure Equipment Directive (97/23/EC)
to obtain optimum sealing. The cable entry
gasket must obtain firm contact with the cable.
For sensors DN 2+3 in applications with low
conductivity and high vibration level of cables
use low noise coax electrode cable.
