Overview
SITRANS F M electromagnetic flowmeters are designed to measure the flow of conductive media.
The complete SITRANS F M series includes three different types of flowmeters, covering all applications using electromagnetic flowmeters, thus Siemens can uniquely meet specific applications:
Modular DC pulse flowmeters cover all common applications in all industries. The diverse components and models in the modular system allow adaptation to various measurement tasks.
SITRANS F M Products
Battery-powered water meters (fully electronic) are ideal for drinking water applications, such as network distribution, billing, and irrigation, where power supply is not available. In addition, they comply with MID (EU) and OIML R49 water meter standards and are MCERTS certified.
SITRANS F M MAG 8000
High-power flowmeters can be used in demanding applications where other flowmeters cannot perform. These flowmeters can handle liquids and slurries in industries such as mining, cement, and pulp and paper.
SITRANS F M 911/TRANSMAG 2
Advantages
Better flexibility
Comprehensive product range
Can use the same transmitter and sensor for compact or remote installation
USMII communication platform, easy integration with all systems
MAG 5000, 6000, 6000 I are easy to commission
All SITRANS F M DC pulse electromagnetic flowmeters are equipped with a SENSORPROM memory chip. Sensor calibration data and transmitter settings are always stored in the chip.
During commissioning, no initialization programming is required.
Factory settings matching the sensor are stored in the SENSORPROM chip, and user settings are automatically downloaded to the SENSORPROM chip. When replacing the transmitter, the new transmitter can directly read the previous data from SENSORPROM for measurement without re-setting.
In addition, during the initial sensor calibration, the "signature" used to connect to the SITRANS F M verifier is also stored.
Easy maintenance
When replacing the transmitter, no re-initialization is required; SENSORPROM automatically updates all settings.
Expansion space
With the USM II "plug and play" universal signal module, the flowmeter can be easily connected to other buses or integrated into other systems, ensuring easy upgrade to higher-level communication/bus platforms.
Applications
Electromagnetic flowmeters are suitable for measuring the flow of almost all conductive liquids, viscous materials, and slurries.
The prerequisite is that the medium must have very low conductivity. The temperature, pressure, density, and viscosity of the medium do not affect the measurement results.
Electromagnetic flowmeters are mainly used in the following areas:
Water and wastewater
Chemical industry
Pharmaceutical industry
Food and beverage industry
Mining, concrete, and cement industry
Pulp and paper industry
Steel industry
Power generation, power industry, and refrigeration industry
The diverse components and models in the modular system allow adaptation to various tasks.

Technical Specifications
Flowmeter accuracy
To ensure flow measurement accuracy, the flowmeter must be calibrated. Calibration is performed at Siemens Flow Products using traceable instruments, with SI units of measurement.
Therefore, the calibration certificate ensures that test results are recognized worldwide, including in the US (NIST traceability).
Siemens can provide accredited calibration according to ISO 17025 in the flow range from 0.0001 m³/h to 10000 m³/h.
Calibration is based on ISO 4185, using two methods: static weighing and reference meter. A measurement uncertainty of ±0.1 % is provided.
The Siemens Flow Instruments accredited laboratory has been certified by ILAC MRA (International Laboratory Accreditation Cooperation – Mutual Recognition Arrangement), ensuring global traceability and recognition of test results.
The calibration certificate is shipped with the sensor, and the calibration data is stored in the SENSORPROM unit.

Flow and velocity diagram
Metric
Size selection table (DN 2 - DN 2000)
This table shows the relationship between flow velocity v, flow rate Q, and sensor size DN.
Sensor selection guide
Minimum range: 0 … 0.25 m/s
Maximum range: 0 … 10 m/s
Normally, the sensor should be selected so that the flow velocity v falls within the range of 1 ~ 3 m/s.
Example:
A flow rate of 50 m3/h and a sensor size of DN 80 provide a flow velocity of 2.7 m/s, which is within the recommended range of 1 to 3 m/s.

Installation conditions
Vibration resistance
Strong vibrations should be avoided.
In cases of severe vibration, a remote transmitter is recommended.
The sensor must be completely filled with liquid.
Install on a full pipe
The sensor must be completely filled with liquid. The following two points should be avoided:
Flowmeter installed at the highest point of the pipe
Installed on a vertical pipe with a free outlet
Do not install on an empty pipe
For partially filled pipes or downward pipes with a free outlet, the flowmeter should be installed at a U-shaped pipe.
When half-full pipe, install at U-shaped pipe
Installation on vertical pipes
It is recommended that the fluid flow direction be upward, which minimizes the effect of bubbles in the liquid on measurement.
Installed on a vertical pipe, fluid flow direction upward
Installation on horizontal pipes
The sensor must be installed as shown in the figure below. It must not be installed as shown in the bottom figure, which would place the measuring electrodes either at a high point of the pipe susceptible to bubbles or at a low point of the pipe where sediment, dirt, etc. may exist.
To measure fluids containing dust
The flowmeter should be installed on a vertical pipe with the fluid flow direction upward
To measure fluids containing dust, the flowmeter should be installed on a vertical pipe with the fluid flow direction upward
Inlet and outlet pipe sections
Recommended straight pipe lengths upstream and downstream of equipment between elbows, pumps, and valves
For the most accurate flow measurement, the upstream and downstream straight pipe lengths must be known. Practical experience has shown that MAG 5100 W and MAG 8000 can operate in non-optimal piping arrangements and provide acceptable accuracy even with zero diameters upstream and downstream.
At the same time, try to center the flowmeter with the pipe flange and gasket.
Ambient temperature - installation
Temperature changes cause expansion or contraction of the piping system. To avoid damage to the sensor, gaskets must be used and appropriate torque applied. For details, refer to the sensor manual.
Potential equalization
Potential equalization
At all times, the potential of the liquid and the potential of the sensor must be equal. Depending on the application, this can be achieved in different ways:
Connect the sensor and adjacent flanges with jumper wires (MAG 1100, MAG 3100)
Direct metal contact between sensor and accessories (MAG 1100 F)
Built-in grounding electrodes (MAG 3100, MAG 5100 W)
Optional grounding/protection flange/grounding ring (MAG 1100, MAG 3100, MAG 8000)
Optional graphite gaskets for MAG 1100 (for MAG 1100 high-temperature version, graphite gaskets are standard)
MAG 8000 installed in plastic or coated pipes: use 2 grounding rings.
Grounding connection
MAG 3100 and MAG 5100 W: conductive and non-conductive pipes have grounding electrodes (no further action required)
MAG 1100 and MAG 3100; no grounding electrodes in conductive pipes (MAG 1100 uses graphite gaskets)
When no grounding electrodes are available, use grounding rings in non-conductive pipes (MAG 1100 uses graphite gaskets)
MAG 1100 F is grounded through the process connection. For detailed information on MAG 8000 grounding
Vacuum
To prevent damage to the liner when operating the instrument under vacuum conditions, please note the "Operating pressure" information given in the "Technical Specifications" section.
Installation of flowmeters on large-diameter pipes
Reducing normal pipe diameter
The flowmeter can be installed between two reducers (e.g., DIN 28545). The figure below shows the pressure drop curve assuming a reduction angle of 8°. This curve applies to water as the medium.
Curve of pipe diameter reduction versus pressure drop between reducers
Example:
In the sensor, at a flow velocity (v) of 3 m/s (10 ft/s), when the diameter is reduced from DN 100 (4") to DN 80 (3") (d1/d2 = 0.8), a pressure drop of 2.9 mbar (0.04 psi) is generated.
Ambient temperature
Curve of maximum ambient temperature versus medium temperature
The transmitter can be installed compact or remote.
For compact installation, the medium temperature must meet the requirements in the figure.
Sensor cable and medium conductivity
Compact installation:
Liquid conductivity ≥5 µS/cm.
Remote version
Minimum conductivity of the medium (using standard electrode cable)
Conductivity of the medium (using special electrode cable)
Empty pipe detection
Installation must meet the following restrictions regarding the use of the empty pipe detection function:
Medium conductivity ≥ 20 μS/cm
Cable length in remote version ≤ 50 m (150 ft)
And special cable is required.
