Abstract: A device for accurately maintaining a constant volumetric proportion between liquids delivered to a mixing point. The device includes means for positively metering the volume of a principal liquid; means for controllably pumping a secondary liquid, means for utilizing the output of the metering apparatus to operate and control the pumping apparatus; means for passing the secondary liquid to and away from the pumping apparatus; means for manually establishing a desired volumetric proportion between the principal and secondary liquids, and means for registering the volume of primary liquid which has passed through the positive metering apparatus. The device is particularly useful in applications wherein the volumetric proportion of a principal liquid to a secondary liquid in a mixture must be accurately controlled.
