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.

摘要： A method and an apparatus for determining at least one flow characteristic of an essentially laminarly flowing, gaseous or liquid medium in a pipeline. Distinguishing features include: that at least one modulation element introduced into, or placed in, the pipeline produces, at least for the case, in which the medium is flowing with a velocity different from zero, a change in density of the medium, at least at times, in the vicinity of the modulation element; that at least one mechanically oscillatable unit introduced into, or placed in, the pipeline and spaced from the modulation element is excited to resonant oscillations; that mechanical oscillations are received by the mechanically oscillatable unit and converted into an electrical, received signal, wherein the received signal is sensitive to the density change; and that the at least one flow characteristic of the medium is determined from the reaction of the received signal of the mechanically oscillatable unit to the density change.
