SITRANS FM MAG 3100 - Electromagnetic Flow Sensor

SITRANS FM MAG 3100 is an electromagnetic flow sensor for demanding industries, offering flexible material options and high temperature and pressure capabilities.

A compact, wafer-design electromagnetic flow sensor with a stainless steel housing and highly resistant liners for extreme process media and temperatures

Robust electromagnetic flow transmitter for precise measurement of conductive liquids in demanding process and hazardous area applications with fully Ex-rated I/O.

High-accuracy electromagnetic flow transmitter with integrated batch control, plug-in communication modules, and flexible 19-inch rack or wall mounting options.

Engineered for extreme versatility, SITRANS FM MAG 3100 features fully welded carbon or stainless steel construction, withstanding high pressures and heavy mechanical loads. With a vast selection of liners (like PTFE or PFA) and electrodes, it adapts to highly corrosive or abrasive media. Paired with MAG 6000 (19” version) and MAG 6000 I transmitters, this sensor provides long-term stability, validated calibration and minimal maintenance in harsh environments.

Unique SENSORPROM™ technology automatically stores calibration data and settings. This enables true plug-and-play installation and allows for hot-swappable transmitter replacement without reprogramming, saving valuable time.

Meet your specific needs with a vast array of custom configurations. The sensor easily handles aggressive media, high temperatures and hazardous Ex-rated environmentsfor compliance and safety across your plant.

The rugged sensor body delivers exceptional durability and long-term performance. Its robust design minimizes process downtime and reduces total cost of ownership in the most demanding industrial applications.

Ambient temperature: -40 to 100 °C (-40 to +212 °F) Medium temperature: -40 to 180 °C (-40 to 356 °F)

Liners, electrodes, and sensor material

Liners: Soft rubber, EPDM , PTFE, PFA, Ebonite, Linatex Electrodes: AISI 316 Ti (1.4571), Hastelloy C, Platinum, Titanium, Tantalum

Sensor material: Carbon steel (or AISI 304) with corrosion resistant two component epoxy coating or AISI 316 L polished flanges and housing

– Drinking water approvals for EPDM: e.g. WRAS, NSF/ANSI Standard 61, AS/NZS 4020, GB/T 5750, ACS, Belgaqua.

– Drinking water approvals for Ebonite: e.g. WRAS, NSF/ANSI Standard 61/37, AS/NZS 4020, GB/T 5750

Choose from various liner materials like PTFE, PFA or hard rubber and electrodes made of Hastelloy, platinum or titanium for optimal chemical resistance for any process fluid.

Tackle extreme thermal conditions with ease. SITRANS FM MAG 3100 safely measures process liquids at highly elevated temperatures, providing continuous and reliable performance where standard sensor fail.

Maintain measurement confidence and the in-depth, traceable diagnostic capabilities provided by the system.

The SITRANS FM MAG 3100 is engineered for exceptional long-term stability. Its fully welded construction features no moving parts for reliable, maintenance-free operation over many years—even in harsh environments. Regular factory recalibration is typically not required, as the sensor is designed to allow easy, in-situ health checks using the available diagnostics functionality.

When paired with the appropriate SITRANS MAG 6000 I Ex version (metallic enclosure) transmitters, the SITRANS FM MAG 3100 is fully approved for Ex applications (ATEX, IECEx and Cl 1 Div 2). It complies with stringent international standards mentioned above for precise measurement in harsh environments.

You can expect high measurement precision. Every SITRANS FM MAG 3100 sensor undergoes validated calibration in facilities individually accredited to ISO/IEC 17025. You can achieve a standard accuracy of ±0.2% of the flow rate (with SITRANS FM MAG 6000 I and MAG6000 19” rack version). For applications requiring stringent tolerances, special 5-point, 10-point and matched-pair calibrations are also available.
