Claim 11:
12. A method for determining a level of a milling material in a storage container for the milling material of a roller mill, the storage container comprising at least one milling material inlet, at least one milling material outlet and at least one metering device for metering the milling material into a milling gap of the roller mill through the milling material outlet, the method comprising the following steps:
determining a weight force exerted by the milling material with a force transducer arranged in the storage container,
determining a first fill level of the storage container from the weight force determined by the force transducer,
determining attainment of a milling material level in the storage container with a level sensor arranged in the storage container, and
determining a characteristic fill level curve based on the determined first fill level and the milling material level determined by the level sensor.
