Abstract
A system adapted for use to transfer desired volumes of liquid chemicals from supplies of the liquid chemicals to a container. The system includes a reversible D.C. motor driven pump for moving liquid in either of two opposite directions, a counting system for counting part revolutions of the pump, and a calibrated chamber. The pump is operated for a predetermined number of part revolutions, the volume of liquid delivered by those part revolutions is determined using the calibrated chamber, and entered into a computer which then determines the amount of liquid delivered by each part revolution of the pump. In response to appropriate inputs, the computer then determines the number of pump part revolutions needed to deliver a needed amount of liquid to a container, and activates the pump for that number of part revolutions to deliver the needed amount of liquid to the container.
