ABSTRACT:
A method for directly measuring the quantity of milk obtained from a cow being milked by a mechanical milking apparatus, including vacuum separating milk from a milk-air mixture from a cow, continuously freely feeding the separated milk to a measuring chamber, sensing the level of the milk to the measuring chamber at a first level from the bottom thereof, discharging the milk from the measuring chamber through a valved outlet by opening same when the level of the milk in the measuring chamber reaches said first level and determining the quantity (Q) of milk from partial volumes during a plurality of measurement intervals (b.sub.i) during the flow of milk into and out of the measuring chamber. The improvement comprises sensing the level of the milk in the measuring chamber at a second level below said first level, measuring the time (c.sub.i) it takes to fill the measuring chamber, from the second level to the first level, closing the valved outlet when the milk is at the second level and defining each measurement interval (b.sub.i) as including at least one filling time (c.sub.i) and one segment of the time (d.sub.i) during which the valved outlet is open before the filling time (c.sub.i) and after the filling time (c.sub.i). The step of determining Q comprises calculating Q according to ##EQU1##
