Abstract
Material delivery systems, methods of delivering material and methods of calibrating such systems and methods are disclosed. The material delivery system includes a delivery vessel, a load cell, and automated weight calibration device. The delivery vessel has at least an outlet adapted for coupling to an unit. The load cell is configured to provide a metric indicative of an amount of material in the delivery vessel. The automated weight calibration device is configured to impart a known force onto the at least one load cell. A method includes delivering material to a unit and determining how much material is delivered by a change in weight of a delivery vessel, wherein the delivery vessel comprises a load cell; applying a known calibration force to the load cell; and comparing a metric from the load cell of the known calibration with an expected metric.
