ABSTRACT:
A completely enclosed system for volumetric calibration wherein timed valves divert liquid components into separate metering tubes for observation. Pistons or separators in the metering tubes are displaced by the flow of liquid thereto. After the calibration or measurement in the metering tubes, the components are returned to the circulating system by applying a pressure to the metering tubes by means of air or an inert fluid whereby the components are driven back through the valves. A separate displacement cylinder can be coupled to the metering tubes through the inert fluid to measure total displacement of both components.
