Abstract (en)
[origin: WO2022162136A1] The invention relates to a method for determining the quantity of a fluid in a container (B), having the steps of: - transmitting (S20s) a predefined bit sequence using an RF signal for determining channel state information, wherein the signal is aimed at the container (B), and wherein a quantity to be determined is located in the container (B), - receiving (S20) a reflection or transmission of the transmitted RF signal, - evaluating errors and/or error parameters, - comparing errors and/or error parameters with at least one training parameter. The invention also relates to a method for determining the quantity of a fluid in a container (B), having the steps of: - transmitting (S20s) a first part of an analogue RF signal for determining channel state information, wherein the signal is aimed at the container (B), and wherein a quantity to be determined is located in the container (B), - receiving (20) a reflection or transmission of the transmitted RF signal, - evaluating errors and/or error parameters, - comparing errors and/or error parameters with at least one training parameter. The invention also relates to an apparatus for carrying out the methods.
