Siemens SITRANS FM MAG 3100 Electromagnetic Flow Sensor


  • Fully welded construction that is extremely rugged and can withstand special process conditions using extreme measurement electrodes
  • Universal applications – lining and electrodes available for every application
  • High temperature version available up to 356 °F
  • Approved for use in potentially explosive atmospheres

Siemens SITRANS FM MAG 3100 is an electromagnetic flow sensor that offers a diverse selection of liners and electrode materials, along with standard grounding electrodes, making it a versatile choice suitable for nearly any flow application.


SITRANS FM portfolio – our integrated platform enables flexible use of the MAG 5000 / 6000 transmitter for all products (MAG 5100 / 3100/1100):

  • Unique SensorProm technology – stores critical, sensor-specific data and passes it to the transmitter. This allows a simple, flexible commissioning of the sensor.
  • Plug & Play – allows easy on-site replacement and commissioning of the transmitter in just minutes
  • “Hot swapable” – exchangeable during operation
  • Mounting flexibility – compact or separate installation possible
  • Validated calibration ensures accurate flow measurement. Each Siemens flowmeter is calibrated in facilities that are individually accredited to ISO / IEC 17025.
  • Service and diagnostics – designed for MAG on-site verification with traceable certification. Regular calibration of the SITRANS FM Verificator ensures accuracy in the field.
