Abstract
A milk flow indicator comprises a housing in which the milk is adapted to flow upwardly through a seat coacting with a non-return valve having a density higher than that of the milk. The valve is movable upwardly by said milk flow to a first, open position and is movable downwardly, upon cessation of said milk flow, to a second, closed position under the influence of gravity, the sinking velocity and distance of movement of the valve being such that movement of the valve means to said second position takes place after a predetermined time delay.
