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


Cost efficient transmitter, accuracy of + 0.4 % of flow rate

Bus communication, batch function and accuracy of + 0.2 % of flow rate

Alu enclosure, Ex approvals, bus communication, batch function and accuracy of + 0.2 % of flow rate

The transmitter can be combined with the energy calculatorTRANS 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 wastewater applications

  • EPDM liner specifically for drinking water applications requiring special approvals

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

  • Suitable for direct burial and constant flooding (IP68)

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