Fluid Phase and Temperature Measurement with a Single Sensor
In many space-flight applications, it is necessary to know the quantity and distribution of cryogenic liquids in fuel tanks or test vessels. Techniques previously tested for this purpose have proven unsatisfactory in performance areas, such as indication accuracy, reliability, time response or system complexity [1, 2]. The purpose of this paper is to describe a technique which can determine both liquid presence and temperature, and reduce problems previously encountered in studies of liquid-hydrogen behavior under low-gravity conditions.
