Abstract
A method for operating a magnetic-inductive flowmeter that has at least one measuring unit for measuring the flow of a medium through a pipeline, a housing and at least one control and evaluation unit, wherein the measuring unit has at least one coil for generating a magnetic field, and wherein at least one capacitance formed in conjunction with the coil forms a resonant circuit and wherein the resonant circuit has at least one measured variable characterizing it. A particularly reliable operation of the flowmeter is achieved in that the resonant circuit is excited with an excitation frequency, that the measured variable characterizing the resonant circuit is determined, that a comparison value of the measured variable characterizing the resonant circuit for the leak-free case is stored in the control and evaluation unit and that the measured variable characterizing the resonant circuit is compared to the comparison value.
