2089724 9203707 PCTABS00011 Gravimetric metering apparatus for bulk materials is provided, in which a vertically-compliant horizontal platform (3) is supported above a load cell (1) in an operative relationship therewith. A thin, flexible means such as a rotating flexible disk (14) is moveable cyclically from a dispensing location (12), thence across the upper surface of the platform, and thence to a discharge location (21). Data logging and processing equipment connected to the load cell tracks and adds periodic signals from the load cell, whereby with appropriate calibration the total mass passing across the load cell may be measured, whereby metering may be effected. A flexible sealing disk (51) may be interposed between the horizontal bottom (5) and the rotating disk, and sealed against the cylindrical housing. Both the rotating disk and the sealing disk may have ribs (141, 56) thereon to assist in the discharge of the materials. The housing bottom (5) may have a large section thereof removed in the vicinity of the discharge location, thereby allowing the flexible rotating disk (14) to flop down at that location to thereby discharge its load.
