APPARATUS FOR DETERMINING THE FILING LEVEL OF A PRODUCT IN A CONTAINER.

Abstract Apparatus for determining the filling level of a product in a container comprises a transmission unit, which generates high-frequency signals and emits them at a predetermined pulse repetition frequency in the direction of the surface of the filled product, the high-frequency signals being reflected at the surface of the product; a receiving unit, which receives the reflected signals, with a delay circuit, which transforms the high-frequency signals/reflected signals into low-frequency signals in accordance with a predetermined translation factor; and an evaluation unit, which determines the filling level of the product in the container on the basis of the delay time of the signals, wherein the delay circuit (9) has the following elements : a transmission oscillator (14), which generates transmission pulses at a transmission frequency (f2); a sampling oscillator (15), which generates sampling pulses at a sampling frequency (fl), the sampling frequency (fl) being less than the transmission frequency (f2); a digital sampling circuit (17), which samples the transmission pulses with the sampling pulses; a closed-loop/open-loop control unit (16), which sets the difference in frequency (f2 -fl) between the transmission oscillator (14) and the sampling oscillator (15) in such a way that said predetermined translation factor is achieved.
