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 vacuum controller for isolating the vacuum chamber of a vacuum pump, the vacuum controller comprising a shell comprising an inlet and an outlet, the outlet being fluidly connected to the vacuum pump, a diaphragm disposed within the shell and defining a first cavity and a second cavity within the shell, the first and second cavities being on opposite sides of the diaphragm and the second cavity being in fluid communication with the outlet, a pressure balance module adapted to selectively fluidly connect the first and second cavities in an open configuration and a controller adapted to selectively actuate the pressure balance module wherein the diaphragm fluidly restricts at least one of the inlet and the outlet when the pressure balance module is in a closed configuration.

In one aspect, the invention provides a sampling apparatus for taking a representative milk sample in a predetermined quantity range from a conveying line in which milk is conveyed at conveying intervals of unknown length. The sampling apparatus comprises a pump, a controller of the pump, and a sample container connecting element connecting member in communication with the pump, wherein the controller is configured based on the predetermined quantity range and a measured quantity indicating a flow rate of milk conveyed in the conveying line and/or a predetermined quantity indicating a total quantity of milk to be conveyed through the conveying line in a conveying interval, to control a pulsed operation of the pump in a conveying interval, wherein the pump conveys a discrete sample subset along a first conveying direction of the pump during the pulsed operation in each sample pulse interval, and wherein the predetermined quantity range is greater than or equal to a total quantity corresponding to a total number of discrete sample subsets in the conveying interval.

A system comprises a milking box, a robotic attacher, a sensor, and a controller. The milking box has a stall to accommodate a dairy livestock. The stall comprises a first exit gate on a first side of the stall leading to a first sorting region and a second exit gate on a second side of the stall leading to a second sorting region. The robotic attacher extends from the rear between the hind legs of the dairy livestock. The sensor identifies the dairy livestock within the milking box stall. The controller selects and opens the first exit gate or the second exit gate based at least in part upon the identity of the dairy livestock.

A milking arrangement includes robot milking stations connected to a milk conduit with an outlet end. A connection conduit connected to the outlet end includes an outlet member. A cleaning device for cleaning the milk conduit includes a cleaning conduit having a first connection member. A milk tank includes a second connection member. The outlet member is movable between and connectable to the first connection member in a primary state, and to the second connection member in a secondary state. A controller communicates with the milking stations, the cleaning device and a user interface. When determined to change the state, measures for preparing the arrangement for the change are automatically performed. Thereafter, the user interface indicates to an operator that the arrangement is ready for the change.
