(57) Abstract:
The invention relates to a device for determining the level of the
contents (2) in a container (3). The aim of the invention is to realize
a high-precision delay circuit (9). To this end, a delay circuit (9) is
provided with the following elements: an emitting oscillator (14)
that generates emitter pulses with an emitter frequency (f2); a
sampling oscillator (15) that generates sampling pulses with a
sampling frequency (f1), whereby the sampling frequency (f1) is
lower than the emitter frequency (f2); a digital sampling circuit (17)
that samples the emitter pulses with the sampling pulses; a
regulating/control unit (16) that sets the frequency difference (f2 -
f1) between the emitting oscillator (14) and the sampling oscillator
(15) in order to obtain the predetermined translation factor.
