SITRANS FM TRANSMAG 2 with SITRANS FM MAG 911/E

SITRANS FM TRANSMAG 2 is a high-powered electromagnetic flowmeter designed for heavy mining slurries, the pulp and paper industry, and low-conductivity media.

Where conventional DC-pulsed meters lose their signal, the SITRANS FM TRANSMAG 2 continues to measure—even in media containing magnetic particles or up to 70 % solids. Its fully welded construction with IP68 protection and continuous self-diagnostics provide the ruggedness required for demanding environments.

A dedicated slurry mode stabilizes readings in high-solids media and air-entrained flows. Combined with powerful field excitation, it delivers accurate, stable results—even in paper stock with a consistency greater than 3 %.

Handles fluids with a conductivity as low as 1 µS/cm as standard. For particularly demanding media, such as demineralized water, an extended range down to 0.1 µS/cm is available upon request.

SmartPLUG stores factory calibration and sensor data inside the MAG 911/E preamplifier. When powered on, the transmitter reads all the data automatically—no manual parameter entry, fewer errors, and significantly faster startup.

Ambient temperature: -20 to 60 °C (-4 to 140 °F)

Medium temperature: -20 to 150 °C (-4 to 300 °F)

Liners, electrodes, and sensor material

Liners: Neoprene, PTFE, Hard rubber, Linatex, Novolak

Electrodes: AISI 316 Ti (Material No. 1.4571/316 Ti), Hastelloy C4 (Material No. 2.4610), Platinum head with shaft (Material No. 1.4571/316Ti), Titanium, Tantalum

Sensor enclosure: IP67 (NEMA 4x), IP68 (NEMA 6) – optional

High signal resolution, combined with an outstanding 3000:1 turndown ratio, eliminates the need for range switching. A single measuring span covers everything from full flow to near-zero.

A wide selection of liner and electrode materials allows you to tailor the sensor precisely to your process chemistry, temperature, and abrasion requirements.

Connect via HART 5.1 or PROFIBUS PA Profile 2.0 for digital bus communication. Configure remotely using SIMATIC PDM or locally via the multilingual two-line display.

Biomass plants often have difficulty reliably capturing volume flow measurements. High levels of dry solids and fats complicate measurements using an electromagnetic device and make it prone to malfunctions. While pulsed DC meters reach their limits when impurities are present, pulsed AC meters prove their effectiveness even under the harshest conditions.

The SITRANS FM MAG 911/E sensor is available in sizes ranging from DN 15 to DN 1000 (½” to 40″), with multiple flange standards including EN 1092-1, ANSI B16.5, AWWA C-207, and JIS 10K—making it suitable for everything from small process lines to large-diameter pipelines in mining or water applications.

The transmitter uses a 23-bit ultra-low-noise ASIC combined with a digital filter that suppresses electrode noise. The magnetic flux density is continuously monitored by reference coils, and inaccuracies resulting from long-term or temperature drift are automatically compensated for by a self-monitoring circuit. For slurry applications, a dedicated slurry mode further stabilizes the reading.
