Full-Bore Electromagnetic Flow Measurement
The SITRANS FM MAG 3100 is a full-bore electromagnetic flow sensor designed for continuous volume flow measurement of electrically conductive liquids.
Because the measuring tube has no mechanical moving parts or internal restriction, the MAG 3100 provides a reliable solution for industrial processes where low maintenance and stable flow measurement are important. Siemens specifies the sensor for applications across process industries, chemical processing, steel, mining, utilities, power generation, and oil & gas.
Why Choose a Full-Bore MAG 3100?
The full-bore construction allows the process liquid to pass through the complete pipe diameter without an internal obstruction.
This makes the MAG 3100 particularly useful when the process involves:
- Conductive liquids
- Dirty or particle-containing fluids
- Continuous industrial flow measurement
- Applications where pressure loss should be minimized
- Large pipeline flow measurement
Wide DN15 to DN2000 Size Range
The MAG 3100 is available in a very wide nominal diameter range from DN15 to DN2000 (1/2" to 78").
This allows the same sensor family to cover everything from relatively small process lines to large water, utility, mining, and industrial pipelines.
Flexible Lining and Electrode Materials
Process conditions vary significantly between applications, so the MAG 3100 can be configured with different lining and electrode materials.
Depending on the selected configuration, engineers can choose materials suited to:
- General industrial liquids
- Chemically aggressive media
- Abrasive process fluids
- Water and utility applications
- High-demand industrial processes
This flexibility makes the MAG 3100 easier to match to the actual process medium rather than relying on a single standard sensor configuration.
Remote or Integral Installation
The MAG 3100 can be supplied as a sensor for remote transmitter installation or configured with an integral Siemens MAG transmitter, depending on the selected order configuration.
Remote installation can be useful when the flow sensor and transmitter need to be installed separately because of temperature, accessibility, or site layout requirements.
Designed for Demanding Industrial Applications
The MAG 3100 is intended for applications where a rugged electromagnetic flow sensor is required rather than a compact general-purpose flowmeter.

FAQ
What is Siemens 7ME631?
7ME631 is the Siemens order-code family for the SITRANS FM MAG 3100 full-bore electromagnetic flow sensor. It is designed for volume flow measurement of conductive liquids.
What liquids can SITRANS MAG 3100 measure?
The MAG 3100 is designed for electrically conductive liquids. The appropriate lining and electrode materials should be selected according to the conductivity, temperature, chemical properties, and other process conditions of the medium.
What is the measuring diameter range?
The MAG 3100 covers DN15 to DN2000, or approximately 1/2" to 78".
Does MAG 3100 have moving parts?
No. It is an electromagnetic flow sensor without mechanical moving components in the measuring path. This helps reduce mechanical wear and maintenance requirements.
Can MAG 3100 measure dirty liquids?
Yes. Electromagnetic flow measurement is well suited to many conductive process liquids containing suspended particles or solids. The correct liner and electrode materials should be selected according to the specific medium.
What is the difference between MAG 3100 and MAG 5100 W?
The MAG 3100 is a general industrial full-bore electromagnetic sensor designed for a broad range of process industries, with DN15–DN2000 sizes and flexible material configurations. The MAG 5100 W is specifically optimized for water, wastewater, water distribution, and related applications.
Can MAG 3100 be used with a remote transmitter?
Yes. Siemens configurations are available for remote transmitter installation, and selected configurations can also use an integral MAG transmitter.
Is MAG 3100 suitable for large pipelines?
Yes. With sizes extending to DN2000, the MAG 3100 is suitable for large industrial pipelines and utility applications where a full-bore electromagnetic flow sensor is required.
