Abstract

A method for setting a constant magnetic field strength of a magnetic field within a commutation interval using a magnetic-inductive flowmeter having a current controller with which time for setting the constant magnetic field strength of a magnetic field is relatively shorter. Additionally, a first interval having a starting point in time and an ending point in time and a second interval having a starting point in time and an ending point in time are arranged within a commutation interval. A first setpoint current curve for the first interval differs by a difference current curve to effectuate a higher rate of change. A second setpoint current curve is assigned to the constant setpoint current. The current controller is fed the first and second setpoint current curves.
