摘要： An apparatus for establishing and/or monitoring a predetermined filling level in a container is described, in which a fixed phase difference (.DELTA..phi..sub.R), which is independent of the oscillation quality of the apparatus, exists between a transmission signal and a reception signal (E) at the resonant frequency (f.sub.r) of the mechanical oscillatory structure. This apparatus comprises a mechanical oscillatory structure (1), an electromechanical transducer (2) having at least one transmitter (23) and a receiver (24), an evaluation unit (9), which determines the frequency of the reception signal (E), compares it with a reference frequency (f.sub.R) and generates an output signal which indicates that the mechanical oscillatory structure (1) is covered by a charge material if the frequency has a value which is less than the reference frequency (f.sub.R) and a control loop, which regulates a phase difference existing between the electrical transmission signal and the electrical reception signal (E) to a specific, constant value at which the oscillatory structure (1) oscillates at a resonant frequency (f.sub.r). A reception signal line (6), which transmits the reception signal (E), is connected via an electrical impedance (Z) to a transmission signal line (5), which transmits the transmission signal.
