Claim:
A dispensing apparatus comprising: a dispenser that dispenses material into a container; a monitor that monitors the container's weight; a device that stops the dispensing of material into the container; and a control unit which is adapted to: receive a signal from the weight monitor; determine, based on container's tare weight, an amount of material to be dispensed; control the dispensing of material, responsive to that signal; store data about: a tare weight of categories of containers into which material may be dispensed; a target weight of material that is to be dispensed into a container based on the container's measured tare weight; and calibration data which, for a given material, includes data about a weight of material that will be in transit to a container when the dispensing of material into the container is stopped; and stop the dispensing of material into the container when the weight of material in the container plus the weight of material in transit to the container equals the target weight of material that is to be dispensed into the container based on the container's measured tare weight.
