Method for operating a resonant measurement system, especially a Coriolis mass flow meter, so as to be excitable in a linear operating range, the driving terminal current triggered by an electric excitation signal and the driving terminal voltage of the electromagnetic drive triggered by the electric excitation signal are measured. The driving power is determined from the driving terminal current and the driving terminal voltage, and if the driving terminal current exceeds a given maximum driving terminal current, and/or if the driving terminal voltage exceeds a given maximum driving terminal voltage and/or if the driving power exceeds a given maximum driving power, the electric excitation signal is limited to a threshold value such that the driving terminal current remains below the given maximum driving terminal current, and/or the driving terminal voltage remains below the given maximum driving terminal voltage, and/or the driving power remains below the maximum driving power. |
