Abstract

Components of a multi-component mixture are individually fed into a measuring container from the bottom through individual precision valves, the component being fluid rises in the container and its level is monitored by ultrasonic means which, in turn, input the measurement to a computer for comparison in memory to determine volume. When the measured level indicates a desired volume is achieved, the feed valve is closed. The contents are then drained from the bottom of the measuring container into a mixing container, and the next component measured in the same way until all components have been measured or the components are sequentially fed and measured until all of the components are present in the tube before discharge. The operation is under computer control which turns on and off the individual precision feed valves and opens a drain valve to drain the contents from the measuring container as well as determining when the proper volume or weight has been achieved.
