ABSTRACT:
Method and apparatus for automatically supplying containers with a liquid using an electronic scale and high speed microprocessor for measuring the weight of liquid introduced into the containers. The first container is partially filled to a predetermined percentage of a target weight as measured by the scale. Flow into the container is then stopped by closing a valve controlled through the scale and microprocessor. The actual weight of the liquid introduced at this point is measured and a correction factor is determined by subtracting the predetermined percentage weight from the actual weight. Flow into the container is then resumed until a second predetermined weight is achieved as measured by the scale and equal to the target weight minus the correction factor. Flow at this point is stopped by again closing the valve. The actual weight of liquid in the container is again measured and compared with the second predetermined weight to arrive at a correction factor which is used in determining the liquid weight to be introduced into the next container. However the next and subsequent containers are supplied without stoppage until the newly calculated predetermined weight is reached as measured by the scale. For each subsequent container the predetermined weight is calculated using a correction factor calculated at the end of the fill of the previous container.
