Process and arrangement for filling a high pressure gas container with liquefied gas under hydrostatic pressure

Abstract

The invention concerns a process, an arrangement and a device for filling a high pressure gas container (1) with liquefied gas, comprising the following steps connecting the gas container to a metering valve (17) and connecting the metering valve (17) to a first container (21) containing liquefied gas, wherein the first container (21) is positions above the gas container (1) at a geodetic height (H); opening the metering valve (17) and admitting the quantity of liquefied gas is supplied with the first container (21) into the gas container (1) at a hydrostatic pressure that corresponds to the geodetic height (H); closing the metering valve (17). As the hydrostatic pressure may be tightly controlled, the high pressure gas container (1) may be efficiently, reproducible, reliable and economically filled at a particularly high metering precision.
