ABSTRACT:
A very low temperature liquid transfer system of the present invention is constructed with first and second containers, each storing therein very low temperature liquid; a connecting tube for communicatively connecting the first and second containers; a pressure control system for increasing and decreasing a pressure in the first container for pressurized transfer of the very low temperature liquid from the first container into the second container through the connecting tube; a pressure gauge for measuring a pressure in the first container; a liquid level sensor for measuring a quantity of the very low temperature liquid in the second container; and a control which functions to logically determine input signals from the pressure gauge and the liquid level sensor, and to produce an output operating signal to the pressure control system based on the logical determination.
