ABSTRACT:
A drum rotatable about an axis through its center of gravity carries troughs located in a circle concentric to said axis and which are charged at a certain level with flowing material to be measured as to quantity, whereby the drum is influenced by a driving moment from the weight of the charged material. After a certain rotation of the drum, the troughs discharge the charged material at a lower level than said charging level. Means are provided for counteracting rotation of the drum by said driving moment, said means including interconnected scoops arranged in a circle concentric to an axis through the common center of gravity of the scoops, said last axis forming an angle with a vertical line. The drum rotates the scoops around said last-mentioned axis, and the scoops successively elevate a second material from a certain level and discharge it at a higher level. The drum forms a closed chamber containing a certain amount of the second material, and the scoops are located on the inside of the drum within said chamber, whereby an accurate measurement of the weight of the flowing material is effected regardless of changes in the density of the material.
