Abstract
A magnetic-inductive flowmeter and a method for operating the flowmeter are disclosed. The flowmeter includes: a measuring tube for guiding an electrically conductive medium; magnetic field devices which can be energized separately with excitation currents for generating at least one magnetic field passing through the measuring tube; measuring electrodes for capturing a measuring voltages induced in the medium; and a control and evaluation unit for generating the magnetic field by energizing at least one of the magnetic field devices and for calculating the volume flow of the medium through the measuring tube. The method includes: applying excitation currents to the magnetic field devices; capturing measurement voltages; and determining flow-dependent transfer factors from the excitation currents and the measurement voltages caused by the excitation currents; and calculating the volume flow of the medium from the transfer factors.
