Benchmark Gauging System for a Small-Scale Liquid Hydrogen Tank

Abstract
A system to accurately weigh the fluid contents of a small-scale liquid hydrogen test tank has been experimentally verified. It is intended for use as a reference or benchmark system when testing low-gravity liquid quantity gauging concepts in the terrestrial environment. This manuscript describes the weighing system design, calibration and operational results. The reference gauging system has shown a repeatable measurement accuracy of better than 0.5 percent of the full tank liquid weight. Suggestions are given for further refinement of the system which can improve accuracy to 0.10 percent of full scale.Citation
