Siemens SITRANS FM MAG 5100W Electromagnetic Flow Sensor


  • Zero Up and Zero Down installation capabilities
  • Lining specifically for drinking water applications requiring special approvals
  • Increased low flow accuracy for water leak detection (NBR or EPDM lining)
  • Suitable for underground installation and permanent immersion (IP68) or underwater installation
  • Integrated grounding electrodes – no grounding rings required for many applications
  • Short delivery time

Siemens SITRANS FM MAG 5100W Electromagnetic Flow Sensor, with its patented hard rubber NBR or ebonite and EPDM liners, is suitable for a wide range of water-related applications.


  • SITRANS FM portfolio – our integrated platform enables the flexible use of the transmitter MAG 5000 / 6000 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.
