Beschreibung
Zusammenfassung:	A Coriolis mass flow meter comprises a transformer circuit configured to receive and analyze vibration measurement signals to determine mass flow measurement values which represent a mass flow of a fluid and to determine characteristic number values for at least one sensor characteristic number, which characterizes and/or is based on at least one harmonic component of at least one of the vibration measurement signals, wherein each vibration measurement signal includes a useful component, having a frequency corresponding to a drive frequency with an amplitude based on a respective magnetic flux through a respective vibration sensor of the flow meter, and a harmonic component having a frequency corresponding to a whole-number multiple of the drive frequency and an amplitude based on the respective magnetic flux.
