Compression mass gauge testing in a liquid hydrogen dewarThis paper describes testing that was conducted using a mass gauge in a liquid hydrogen environment. The mass gauge, herein referred to as the 'compressibility gauge,' is being developed as a means to accurately determine the mass of liquid contained in a tank in a low-gravity environment. The concept is based on the thermodynamic principle that the pressure of gas or vapor changes when its volume changes. Previous work has been conducted by Southwest Research Institute in collaboration with NASA Lewis Research Center. This consisted of testing the concept with water and other cryogenic simulant fluids. The purpose of conducting liquid hydrogen tests is to test the concept in actual cryogenic conditions, and address hardware issues that arise in fabricating a test article for use in liquid hydrogen.
