Abstract: The object of the invention is to so design a flow-meter system for milk-collecting vehicles, that a pump, a pulse-controlled sampling device, an air separator and a flow-meter with pulse generator and display are in series in the operational direction, where a computer is provided in the display for analysis, in that independently of the particular quantity delivered, Automatically always the same amount of sample shall be withdrawn, whereby an adepquate amount of sample shall be available for analysis even for small quantities delivered, and where addiional containers are not needed for large quantities delivered, and where overrunning is avoided.

Abstract: An improvement in the method and apparatus for obtaining the specific fat content of milk wherein whole milk and skimmed milk are mixed together as they flow, and the amount of skimmed milk is added according to the previously determined fat content of the whole milk, the fluid quantities of the whole milk and skimmed milk being continuously measured. The method and apparatus are improved by continuously taking samples of the whole milk and continuously determining their fat content, and in between taking the samples and the admixture of the skimmed milk while the whole milk is retained in its supply line for the period of time between the taking and/or evaluation of the particular sample and the controlling of the skimmed milk admixture.
