Abstract
Measuring a fill level or limit state is performed using an electromagnetic vibrating system, in which a transmission signal(s) is generated. A vibrating body () is excited into a state of vibration by the transmission signal (s); and by means of the reception signal (e) that is then produced by the vibrating body () the transmission signal (s) is modified for at least one subsequent excitation of the vibrating body (), while a natural frequency (fe) of the vibrating body—or a magnitude (te) dependent on the natural frequency (fe)—is determined from the reception signal (e), and the transmission signal (s) is thereby modified.
