Product introduction
Electromagnetic flowmeters are suitable for measuring the flow of almost all electrically
conducting liquids, pastes and slurries.
A prerequisite is that the medium must have a minimum conductivity of 5 µS/cm and a solid content
of maximum 40%. The temperature, pressure, density, and viscosity have no influence on the result.
The main applications of the electromagnetic flowmeters can be found in the following sectors:
• Water and wastewater
• Chemical and pharmaceutical industries
• Food and beverage industry
• Mining, aggregates and cements industries
• Pulp and paper industry
• Steel industry
• Power; utility and chilled water industry

Product introduction
1. Product introduction
SITRANS F M electromagnetic flowmeters are characterised by simplicity:
? Simple to install
? Simple to commission
? Simple to operate
? Simple to maintain
SITRANS F M electromagnetic flowmeters are manufactured by Siemens Flow Instruments A/S
- one of the world's leading manufacturers of flowmeters. specified settings are downloaded to the
SENSORPROM® unit. Should the transmitter be replaced, the new transmitter will upload all
previous settings and resume measurement without any need for re-programming.
Furthermore, the "fingerprint" used in connection with the Siemens Flow Instruments Verificator is
stored during the sensor calibration.

USM II "Plug & Play" add-on communication modules.
USM II - the Universal Signal Module with "Plug & Play" simplicity makes it easy to access and integrate
the flow measurement with almost any system. It ensures the flowmeter will be easy to upgrade to new
communication platforms in the future, too.

Mode of operation
The flow measuring principle is based on Faraday’s law of electromagnetic induction.
Ui = When an electrical conductor of length L is moved at velocity v, perpendicular to the lines of
flux through a magnetic field of strength B, the voltage Ui is induced at the ends of the conductor
Ui = L x B x v
Ui = Induced voltage
L = Conductor length = Inner pipe diameter = k1
B = Magnetic field strength = k2
v = Velocity of conductor (media)
k = k1 x k2
Ui = k x v, the electrode signal is directly proportional to the fluid velocity
A flowmeter consists of a sensor (MAG 1100, MAG 1100 F, MAG 3100, MAG 3100 P or MAG 5100 W)
and a transmitter (MAG 5000 or 6000).
SENSOR
The sensor converts the flow into an electrical voltage (Ui) proportional to the velocity of the flow.
The sensor is built up of a stainless steel pipe, 2 coils, electrodes, an isolating liner, housing and,
where applicable, connecting flanges.
TRANSMITTER
The transmitter consists of a number of function blocks which convert the sensor voltage into flow
readings.
Power supply
Two different types of power supply are available. A 12 ... 24 V AC/DC and a 115 ... 230 V AC switch
mode type.
Coil current module generates a pulsating magnetizing current that drives the coils in the sensor.
The current is permanently monitored and corrected. Errors or cable faults are registered by the selfmonitoring
circuit.
Input circuit amplifies the flow proportional signal from the electrodes. The input impedance is
extremely high: >1014 ? which allows flow measurements on fluids with conductivities as low as
5 µS/cm. Measuring errors due to cable capacitance are eliminated due to active cable screening.
Digital signal processor converts the analog flow signal to a digital signal and suppresses
electrode noise through a digital filter. Inaccuracies in the transmitter as a result of long-term drift
and temperature drift are monitored and continuously compensated for via the self-monitoring
circuit. The analog to digital conversion takes place in an ultra low noise ASIC with 23 bit signal
resolution. This has eliminated the need for range switching. The dynamic range of the transmitter
is therefore unsurpassed with a turn down ratio of minimum 3000:1.
CAN communication
The transmitter operates internally via an internal CAN communication bus. Signals are transferred
through a signal conditioner to the display module, and to/from internal/external option modules
and the dialog module.
Dialog module
The display unit consists of a 3-line display and a 6-key keypad. The display shows a flow rate or
a totalizer value as primary reading.
Output module converts flow data to an analog, a digital and a relay output. The outputs are
galvanically isolated and can be individually set to suit a particular application.

Detection of empty pipe (special cable required in remote mounted installation)
Depends on sensor size

For detection of empty sensor the min. conductivity must always be >50 µS/cm and the max. length
of the electrode cable when remote mounted is 50 meters (164 ft). Special cable must be used!
For 19" Ex applications with safety barriers special cable cannot be used and the empty pipe
function can therefore not be used. For these applications 25 meters (82 ft) of cable can be used
in order to obtain 0.25% and 50 meters (164 ft) to obtain 0.5%.
For remote MID installations the max. cable length is 3 meters (9.8 ft). For other CT application
standard requirements are applicable.
Empty sensor detection is not available with DN 2, 3 (1/12, 1/8 inch) sizes.
Guidelines for selection of sensor
Min. measuring range: 0 ... 0.25 m/s
Max. measuring range: 0 ... 10 m/s
Normally the sensor size is selected so that the nominal flow velocity v lies within the measuring
range 1 ... 3 m/s.
Guidelines for selection of sensor
Min. measuring range: (0 ... 0.8 ft./sec)
Max. measuring range: (0 ... 33 ft./sec)
Normally the sensor size is selected so that the nominal flow velocity v lies within the measuring
range (1 ... 15 ft./sec.)

Installation conditions
Transmitter can be mounted compact or remote.
The sensor must always be completely full with liquid.
(For further details see approval : DK-0200-MI001-001)
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.
Recommended flow direction: upwards. This minimizes the effect on the measurement of
any gas/air bubbles in the liquid.

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.

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.

Potential equalization
The electrical potential of the liquid must always be equal to the electrical potential of the sensor.
This can be achieved in different ways depending on the application:
A. Wire jumper between sensor and adjacent
flanges. (MAG 1100 and MAG 3100).
B. Direct metallic contact between sensor and
fittings. (MAG 1100 FOOD).
C. Built-in grounding electrodes. (MAG 3100
and MAG 5100 W).
D. Optional earthing/protection flanges/rings.
(MAG 1100 and MAG 3100).
E. Optional graphite gaskets on MAG 1100.
(Standard for MAG 1100 High temperature).

Vacuum
The flowmeter can be installed between two reducers (e.g. DIN 28545). At 8° the following
pressure drop curves apply. The curves are applicable to water.

Compact/remote installation
Max. ambient temperature as a function of temperature of medium.
The transmitter can be installed either compact or remote.
With compact installation the medium temperature must be in accordance with the graph.
With remote installation, the cable length and type described under "Technical data", chapter
2 must be used.

IP 68 applications only
If the sensor is buried or permanently submerged, the terminal box must be encapsulated
with silicon dielectric gel.
Mix the two components well and pour the contents into the terminal box.
The material is a non-toxic, transparent, selfhealing gel which cures in approx. 24 hours at
approx. 25°C (77°F) (curing time will increase by 100% per -10 °C).
The gel can be penetrated with test instruments or be removed in case of cable replacement.
The potting kit cannot be used for ATEX applications.

Suggestions for the direct burial of MAG 3100 & MAG 5100 W sensors
If MAG 3100 or MAG 5100 W sensors are buried directly into the ground, the SENSORPROM®
unit should be removed from the terminal box on the sensor and relocated in the remote
transmitter prior to burying the sensor.

AC-cleaning
AC-cleaning is used to remove fatty deposits on the electrodes. These fatty deposits are seen in
wastewater applications, in abbatoirs and water applications with oil residuals. During the cleaning
process, the surface of the electrodes get warmer, which tends to soften grease particles and the
gas bubbles generated mechanically lift deposits away from the surface of the electrodes.

DC-cleaning
DC-cleaning is used to eliminate electrically conductive deposits in the measuring pipe influencing
the measuring accuracy.
Particularly in district heating applications an electrically conductive deposit (magnetite) may occur
and short-circuit the electrode signal. In this case the accuracy of the meter decreases and the
signal/noise conditions of the meter become inferior. The problem only arises if the conductivity of
the water is less than approx. 250 µS/cm.
During DC-cleaning, electrolysis takes place where the flow of electrons removes the particle
deposits from the electrode area.

Custody transfer approval

A transmitter can be supplied in a version tested and approved for custody transfer (CT). The
internal counter can accordingly be used for charging.
This requires verification, sealing and setting of the transmitter together with the sensor for a
specific flow range. After sealing the data on the transmitter must not be changed.
The sealing of the transmitter is done by placing sealing marks on the transmitter and on the
connection plate in the terminal box.

P indicates sealing locations

Potential equalization
To obtain optimum results from the measuring system, the chassis body of the sensor must have
the same electrical potential as the liquid being measured.

MAG 1100 F
The sensor must be installed between two adapters.
Potential equalization with the liquid occurs automatically via these adapters and
through the adjacent pipe.

MAG 3100 / MAG 5100 W (except PTFE and PFA liner)
Potential equalization is carried out with the built-in grounding electrodes. No further actions
need to be taken.
Please note: MAG 3100 has no grounding electrodes if the electrodes materials are
platinium or tantalum or PN 100.

Installation of sensor
MAG 3100 (PTFE liner and PFA)
Electrically conductive piping Use an earth strap on one side.
Non-conductive piping
Use an earthing flange. Place the flange between flowmeter and the adjacent pipe flange.
Selection of earthing flange depends on the medium, liner material and application.

Inlet protection MAG 3100
With abrasive liquids, flowmeter inlet protection may be necessary. Here type C and E earthing
flanges are used.
Type C (for all liners except PTFE and PFA) is clamped between the flanges.
Type E (for PTFE liner only) is fitted to the flange.
Flat ring (for PFA liner only) is fitted to the flange.
When using an earthing flange, gaskets must always be used between the adjacent pipe
flange and the earthing flange.

Cathodic protected piping
Special attention must be given to systems with cathodic protection.
Compact installation:
The transmitter must be supplied through an isolation transformer. The terminal "PE" must
never be connected.
Remote installation:
The screen must only be connected at the sensor end via a 1.5 µF condensator. The
screen must never be connected at both ends.
Isolated sensor:
If above mentioned connections are unacceptable, the sensor must be isolated from the pipe work.
The bolts must be isolated from pipe.
