Milk meter (10) for milking plants comprising an upper collecting chamber (30) delimited at the top by a covering membrane (33), a first discharge opening (22) connectable to a milk passage manifold of a milking plant, said first discharge opening (22) being adapted to put in communication the milk passage manifold with the upper collecting chamber (30), a lower measuring chamber (40) connected to the upper collecting chamber (30) and communicating with it by means of a second discharge opening (32), a shutter (31) comprising a central portion (36), adapted to open and/or close the second discharge opening (32), and an upper portion (37) connected to the central portion (36) and associated with the covering membrane (33), wherein the central portion (36) of the shutter (31) comprises a chimney (51) to discharge upwards, that is towards the upper collecting chamber (30) and towards the first discharge opening (22), the air rising from the lower measuring chamber (40) when the latter chamber becomes filled with milk.

A milk sampling device includes a housing forming an inner space, an inlet opening to the inner space, a deflector member with an upper surface mounted in the inner space of the housing in a position vertically below the inlet opening, a flow passage formed between a periphery edge portion of the deflector member and an inner surface of the housing, and a milk sampling passage provided with an opening which constitutes a part of the flow passage. The upper surface of the deflector member comprises a plurality of a upwardly extending members arranged at a distance from each other in the vicinity of the periphery edge portion of the deflector member such that flow channels are formed between adjacent upwardly extending members.

An inline analyzer for a milking machine system includes an outer body having a central axis, a fluid input channel, an upper cover attached to the fluid input channel, a central portion attached to the upper cover, a lower portion attached to the central portion, and a fluid output channel attached to the lower portion, wherein the fluid input channel, the central portion and the fluid output channel each have a hollow central channel. A float portion is disposed loosely within the outer body and is free to move axially along the central axis such that milk flows around the float portion. Electrode(s) extend through an upper portion of the float portion. A battery, processor(s), memory and actuator are disposed within float portion. The actuator causes the float portion to move axially along the outer body central to regulate the flow of milk through the outer body.

A milking system for milking a dairy animal includes a milking cup and a measuring chamber which is in flow communication with the milking cup for the obtained milk where the chamber has a sensor system for measuring at least one property of the milk. The sensor system includes at least three optical sensor devices, each configured to measure values of a property of the milk, and a sensor control unit for actuating the sensor system and for processing the measured values. The sensor control unit is configured to repeatedly select one of the sensor devices. Two of the optical sensor devices are identical, and the sensor system is configured to in each case measure the local value of the property of the milk and to determine a value of the at least one property of the milk in the measuring chamber on the basis of the values measured locally.

A milk pump device, comprising a passage duct, a first one-way valve, a second one-way valve and a membrane pump. The first and second one-way valves are included in the passage duct and oriented in the same direction relative to each other. The membrane pump is positioned between the first one-way valve and the second one-way valve. The membrane pump forms a first milk meter for generating a first milk measurement with respect to a number of complete pumping strokes of the membrane pump. The milk pump device further comprises a second milk meter for carrying out a second milk measurement with respect to a residual pumping stroke.
