Abstract: A method is proposed for ascertaining the quality and/or the composition of milk, in particular during a milking operation, in which the fill level of the milk in a chamber is determined. After the fill level of the milk in the chamber has been determined, the milk is irradiated using at least one radiation of a predefined wavelength. The intensity of the reflected radiation is measured. The fill level and the intensity of the reflected radiation represent a value pair. Characteristic values are stored in a memory. A characteristic value is assigned to the ascertained value pair. A statement about the quality and/or the composition of the milk can be made from the characteristic value thus ascertained.

Abstract: The invention relates to a method and device for determining the volumetric flow rate of milk flowing during a milking process. A cross-sectional area (Ai) of the milk flow (2) is determined at a first measuring point (3) by means of a sensor (4) which is arranged outside the flowing milk. The time (ti) required by the milk flow (2) with the determined cross-sectional are (Ai), to go from the first measuring point (3) to a second measuring point (5) which is provided downstream from the first measuring point, is measured. The flow speed (vi) is derived from the measured time (ti) and the known distance (s) between the first and second measuring points (3, 5). The volumetric flow rate (V(t)) is determined on the basis of the determined cross-sectional area (Ai) and the flow speed (vi).
