A system for automatically and accurately transferring/transporting quantities of liquids from bulk storage source tanks to mixing/processing tanks with minimal contamination of the liquids or to the surrounding environment. The several bulk storage source tanks are individually connected by associated pumps and control valves to a corresponding plurality of first couplers fixedly mounted on a terminal panel in an array of predetermined geometry. A second coupler, adapted for selective mating engagement with the first couplers, is carried by a robotic arm that is movably mounted on a support base for bringing the second coupler selectively into registry and coupling engagement with any one of the first couplers. Motion of the arm and engagement/disengagement of the couplers, as well as operation of the several storage source pumps and appropriate control valves, are all controlled by a process controller/computer, which also receives an input from a mass flow meter for determining quantity of liquid transferred to the mixing/processing tank from each storage tank. The couplers are of the locking dry-break type to minimize spillage or leakage during the coupling/decoupling and liquid transport operation.
