A method for detecting a filling level in a tissue dispenser for dispensing portions of a continuous web of tissue from a tissue roll, the method comprising - counting portions of the tissue dispensed by the tissue dispenser, - determining an initial filling level depending on the counter data and an initial tissue type information, - determining a verified filling level depending on the counter data when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, and - determining a verified tissue type information when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, wherein the verified tissue type information is determined at the time of the roll exchange, - wherein the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined, - wherein the verified filling level is determined taking into account the event of the change in position of the tissue roll and the counter data corresponding to this time of exchange of a tissue roll from a first tissue roll position to a second tissue roll position, and - wherein the determination of the verified filling level depends on data relating to the roll exchange, namely a reduced diameter of the tissue roll at the time of the roll exchange and/or a maximum diameter of the tissue roll in the second tissue roll position, characterized in that: - the initial tissue type information is an information which is set in a default, - the initial tissue type information corresponds to a standard tissue type, - the tissue type information comprises information on at least one or more of the following: ∘ length of tissue on the tissue roll, ∘ number of layers, ∘ thickness of tissue, ∘ tissue material, ∘ single use or multiuse tissue, - the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined. - counting portions of the tissue dispensed by the tissue dispenser, - determining an initial filling level depending on the counter data and an initial tissue type information, - determining a verified filling level depending on the counter data when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, and - determining a verified tissue type information when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, wherein the verified tissue type information is determined at the time of the roll exchange, - wherein the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined, - wherein the verified filling level is determined taking into account the event of the change in position of the tissue roll and the counter data corresponding to this time of exchange of a tissue roll from a first tissue roll position to a second tissue roll position, and - wherein the determination of the verified filling level depends on data relating to the roll exchange, namely a reduced diameter of the tissue roll at the time of the roll exchange and/or a maximum diameter of the tissue roll in the second tissue roll position, characterized in that: - the initial tissue type information is an information which is set in a default, - the initial tissue type information corresponds to a standard tissue type, - the tissue type information comprises information on at least one or more of the following: ∘ length of tissue on the tissue roll, ∘ number of layers, ∘ thickness of tissue, ∘ tissue material, ∘ single use or multiuse tissue, ∘ length of tissue on the tissue roll, ∘ number of layers, ∘ thickness of tissue, ∘ tissue material, ∘ single use or multiuse tissue, - the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined.
