Electromagnetic Flowmeters

General purpose magnetic inductive flowmeter for applications in the water / waste water industry


The field of application for all electromagnetic flowmeters of the SpiraMAG® series is the measurement of conductive liquids (>5µS/cm) like water, waste water in continuous flow measurement.
The series comprises the nominal diameters DN 15 to DN 1000 and is available in the pressure stages PN 10/16/40. The standard maximum temperature is 60°C.
Different connections and output signals are available.
