Device for measuring the milk quantity and/or monitoring the milk flow and process for measuring the quantity of milk yielded by a cow during a milking operation and/or for monitoring the milk flow during the milking operation using the device

摘要

For measuring the amount of milk yielded by a cow during a milking operation or for monitoring the milk flow during the milking operation, an air separation chamber (1) to which a vacuum can be applied and which is connected to a milk feedline (2) and a measurement chamber (3) connected to the air separation chamber (1) via a closable milk inlet opening (4) and having a milk outlet (5) are arranged one above the other. A measuring device (8) with a magnetic float (10) guided on a tube (13) and at least one switch contact (9) actuatable by the float (10) depending on the height of the milk level is provided in the measuring chamber (3). The measuring device is connected to a counting device and/or display device (12) which receives pulses from the switch contact or the switch contacts. The magnetic float (10) is guided on a vent tube (13) which terminates at a distance from the milk inlet opening (4) and has a vent valve (14). The vent tube bears in the measurement chamber (3) at the air outlet end (13a) a separating valve (15), preferably a disc valve, which releases the milk inlet opening (4) in the case of a vacuum in both chambers (1, 3) and closes said opening upon venting, in a manner so as to be movable through a guide tube (16) projecting into both chambers (1, 3) and vertically movable in the vent tube (16).
