ABSTRACT:
Gravimetric metering apparatus for bulk materials is provided, in which a vertically-compliant horizontal platform is supported above a load cell in an operative relationship therewith for detection of weight on the platform. A thin rotating flexible disk is moveable cyclically from a dispensing location, thence across the upper surface of the platform, and thence to a discharge location. 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.
