CLAIMS

1 . A milking system for milking a dairy animal, and comprising

- at least one milking cup having a first milk outflow opening,

- a measuring chamber having a milk inlet which is in flow communication with the first milk outflow opening, with a second milk outflow opening to a milk hose, and with a vacuum connection,

- a level sensor for measuring a milk level in the measuring chamber,

- a controllable valve having an adjustable passage opening, which is provided in or downstream of the second milk outflow opening, and

- a control unit which is operatively connected to the level sensor and the valve, and which is configured to adjust the passage opening of the valve on the basis of the measured milk level.

2. The milking system as claimed in claim 1 , wherein the measuring chamber is directly and rigidly connected to the milking cup, and in particular wherein the milking cup and the measuring chamber form one rigid unit.

3. The milking system as claimed in one of the preceding claims, wherein the control unit is configured to adjust, in particular continuously adjust, the passage opening between a smallest open position and a largest open position during at least a part of a milking operation, more particularly at least during a main milking phase of the milking operation.

4. The milking system as claimed in one of the preceding claims, wherein the control unit is configured to enlarge the passage opening in the case of a rising milk level and reduce the passage opening in the case of a falling milk level.

5. The milking system as claimed in claim 4, wherein the control unit is configured to adjust the passage opening in such a way that the aim is a milk level which remains the same.

6. The milking system as claimed in one of the preceding claims, wherein the level sensor extends substantially vertically over an internal height of the measuring chamber during milking, and in particular comprises a series of mutually separate electrodes which are electrically connectable via a sensor control unit.

7. The milking system as claimed in one of the preceding claims, comprising an inclination sensor for determining an inclination of the milking cup, wherein the control unit is operatively connected to the inclination sensor and is configured to correct the measured milk level on the basis of the determined inclination.

8. The milking system as claimed in one of the preceding claims, wherein the valve is provided in the measuring chamber, in particular in the second milk outflow opening.

9. The milking system as claimed in one of the preceding claims, comprising a milk flow meter which is configured to determine the milk flow through the second milk outflow opening on the basis of the passage opening of the valve.

10. The milking system as claimed in claim 9, comprising a pressure measuring device configured to measure a pressure difference over the valve and/or the passage opening, in particular comprising a first pressure sensor configured to measure a pressure in the measuring chamber, and a second pressure sensor to measure a pressure in the milk hose, more particularly past the valve.

1 1 . The milking system as claimed in claim 9 or 10, comprising a height determining device configured to determine a milking height at which the measuring chamber is located during milking of the dairy animal, in particular also a valve height at which the valve is located during milking, and wherein the milk flow meter is operatively connected to the height determining device and is configured to determine the milk flow on the basis of the determined milking height, and in particular also the valve height.

12. The milking system as claimed in one of the preceding claims, comprising a milk hose milk flow meter in or around the milk hose for measuring the milk flow, in particular a contactlessly measuring milk hose milk flow meter, more particularly an electrically or electromagnetically operated milk hose milk flow meter, advantageously a magnetohydrodynamic milk hose milk flow meter.

13. The milking system as claimed in one of the preceding claims, wherein the measuring chamber has a, preferably rounded or round, cross section that increases away from the milk inlet.

14. The milking system as claimed in one of the preceding claims, comprising an additional sensor for measuring a milk-related property, in particular a sensor for measuring a milk property.

15. The milking system as claimed in one of the preceding claims, dependent on claim 9 or 12, wherein the control unit is configured to control the valve in such a way that the milk level increases if the determined or measured milk flow falls below a threshold value.
