A milk flow meter having a measuring chamber which is connected to a milk supply conduit, the measuring chamber communicating with a discharge chamber and a milk sump at the lower end thereof. A calibrated milk discharge opening is provided between the measuring chamber and the discharge chamber and a milk suction conduit is connected to said milk sump. An additional rinsing conduit is provided, the upper end of the rinsing conduit leading into the discharge chamber and/or the measuring chamber essentially on the level of the upper end of the measuring chamber and the other end of the rinsing conduit being adapted to be connected, with the aid of an adjustment means movable between a measuring position and a rinsing position, essentially exclusively to the milk suction conduit in the rinsing position. In this respect, small passage conduits are preferably provided which connect the suction conduit with the sump and the discharge chamber in the rinsing position of the adjustment means so that the milk flowmeter can be completely emptied of rinsing liquid at the end of a rinsing procedure.
A milk flow meter comprising a measuring chamber connected to a milk supply conduit, a discharge chamber having means therein defining a milk sump at a lower end thereof, calibrated passageway means for providing a fluid connection between said measuring chamber and said discharge chamber, a milk suction conduit connected to said milk sump, means defining a rinsing conduit connected in fluid circuit with and extending between at least one of said measuring chamber and said discharge chamber at a first end thereof and said milk sump at a second end thereof, said first end being oriented adjacent an upper end of said measuring chamber and said discharge chamber, respectively, and an adjustment means selectively controllable between a first condition and a fluid restricting second condition for controlling a flow of a rinsing liquid between said at least one measuring chamber and said discharge chamber and said milk sump, said first condition providing a nearly unobstructed fluid path between said at least one of said measuring chamber and said discharge chamber and said milk sump, said second condition providing a restricted flow between said at least one of said measuring chamber and said discharge chamber and said milk sump and a nearly unobstructed path between said rinsing conduit and said milk sump.
