ABSTRACT:
An apparatus for measuring and/or sampling the milk-yield of a cow during milking is described. The apparatus comprises a housing with a milk inlet and a milk outlet and a rotation-symmetric distributing means mounted in a drain chamber. A buffer chamber is formed in the housing above the drain chamber, in which buffer chamber the incoming milk stream is received. The buffer chamber is connected to the drain chamber by a cylindrical bore formed in its bottom wall, said bore being coaxial with the distributing means. Means are provided adapted to permit a milk flow to the distributing means through the cylindrical bore only when a predetermined milk quantity is received in the buffer chamber, said means interrupting said milk flow at a second smaller milk quantity in the buffer chamber. The distributing means provides a radial flowing milk film a portion of which is conducted to a measuring means through a receiving chamber. In this manner, it is quaranteed that under all circumstances a uniform milk flow is supplied to the distributing means, whereby a very high measuring accuracy is obtained.
