 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

Application examples: Water abstraction, Water distribution network, Waste water and as custody transfer water meter or cooling meter.


  • Short lead time

  • Rugged NBR hard rubber liner for all water and wastewater applications

  • EPDM liner specifically for drinking water applications requiring special approvals

  • Ebonite liner for drinking water, water and wastewater applications

  • Increased low flow accuracy for water leakage detection (Ebonite or EPDM liner)

  • Suitable for direct burial and constant flooding (IP68)

  • Designed to allow patented MAG in-situ verification using the SENSORPROM fingerprint
