Select and order

In order to have a complete flowmeter, please combine it with one of the following MAG transmitters: 


SITRANS FM MAG 5000: Cost efficient transmitter, accuracy of + 0.4 % of flow rate

SITRANS FM MAG 6000: Bus communication, batch function and accuracy of + 0.2 % of flow rate

SITRANS FM MAG 6000 I: Alu enclosure, Ex approvals, bus communication, batch function and accuracy of + 0.2 % of flow rate


The transmitter can be combined with the energy calculator SITRANS FUE950


  • 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
  • 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.
