METHOD FOR ADJUSTING A CONSTANT MAGNETIC FIELD STRENGTH OF A MAGNETIC FIELD IN A MAGNETIC INDUCTIVE FLOW METER AND RELATED MAGNETIC-INDUCTIVE FLOW METER

摘要

Shown and described is a method for adjusting a constant magnetic field strength of a magnetic field (4) within a Kommutienmgsintervalls with a magnetic-inductive flowmeter (1) with a current regulator (6).; The invention has for its object to provide a method for adjusting the constant magnetic field strength, in which the settling time is shortened as compared to the prior art.; The object is achieved in that a first interval having a start time and an end time and a second interval having a start time and an end time are disposed within the Kommutienmgsintervalls that a first predetermined current profile is determined for the first interval, said first target current waveform to a differential current course deviates from the desired constant current such that the difference current profile compared with the constant reference current, causes a higher rate of change of magnetic field strength toward the constant magnetic field strength that a second target current profile is determined for the second interval by the constant target current is assigned to the second desired current profile and that (the current controller 6 ) is specified in the first interval of the first predetermined current profile and the second interval of the second desired current waveform.
