“…A combined calorimetric and radio-frequency method was used to measure the mass flow rate of twophase helium [2]. Relative error of 5-15% was obtained for void fraction <0.8 and error > 15% for void fraction > 0.8 for flow rates between 1 and 5.5 g/s in a 20mm ID pipe.…”

Cryogenic fluid flow is a critical measurement parameter but is difficult to properly measure due to the extreme environmental conditions and the frequent presence of multiphase flow during saturated liquid transfers. Multiphase flow proves challenging for most flow measurement methodologies; furthermore, additional measurements of volume fraction, quality, and slip velocity are often required. In-line capacitance-based sensors have the potential to overcome these limitations. In this paper, a capacitance sensor in a multiphase cryogenic flow loop is evaluated for its ability to measure liquid volume fraction, gas phase velocity, and total mass flow rate for two-phase cryogenic nitrogen flow.
