  • Publication number: 20240353251
    Abstract: A measuring system for detecting a boundary layer on a product in a container includes a radar-based measuring device with an antenna or a measuring sensor for transmitting high-frequency signals toward the product and, after reflection at the product surface, for receiving as received signals; a signal generation unit that generates the high-frequency signal; and a receiving unit that to record the received signal. The measuring system further includes an evaluation unit in which a machine learning algorithm is formed to detect the boundary layer on the basis of the received signal. The implementation of a machine learning algorithm according to the invention avoids the problem that the boundary layer or the additive product layer in the received signal often does not generate a clearly assignable signal maximum, which known distance measurement methods according to the prior art require for its detection.
