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.

Gravimetric metering apparatus for metering the flow of bulk materials, comprising:
- a vertically-compliant horizontal platform supported above a load sensor in an operative relationship therewith for detection of weight on said platform;
- thin, flexible means moveable cyclically from a dispensing location, thence across the upper surface of said platform, and thence to a discharge location;
- dispensing means for dispensing said material onto said thin flexible means at said dispensing location;
- means for removing material from said thin, flexible means at said discharge location, and
- data logging and processing means connected to said load sensor for logging and adding signals periodically from said load sensor, whereby with appropriate calibration a total mass passing across said load sensor may be measured, whereby metering may be effected.
