Abstract

A vertically-oriented cryogenic fluid cylinder includes an inner vessel for holding cryogenic fluid, an outer vessel surrounding the inner vessel, and a liquid level gauge for indicating a liquid level within the inner vessel. The liquid level gage includes a level indicator located outside of the outer vessel, a support arm extending down into the inner vessel, a swing arm pivotably secured to the support arm and connected to the level indicator so that angular position of the swing arm provides an indication of liquid level within the inner vessel on the level indicator, and a float on the swing arm that pivots the swing arm as the liquid level rises and lowers. The support arm forms an acute angle with the central longitudinal axis of the inner vessel so that the swing arm can be longer to move over a larger portion of the length of the inner vessel.
