A gravity process for the metering and feeding of carrier particles into a feeder line wherein prefeeding is avoided. The process utilizes an electromechanical vibratory feeder to meter carrier particles, comprised of for example iron, steel, or ferrites coated with a polymer, or mixture of polymers, to an inline gain in weight hopper. When the predetermined weight target is achieved the feeder is turned off and the weighed carrier is released from the hopper. The charge of carrier can be caused to flow through a funnel to a bottle conveyed on a single fill line. No internal moving parts are associated with the feeder thus the cleaning thereof is simplified and carrier weighing accuracy is excellent. The feeder selected can be a 6 inch Model RS Siletta.
