CONTINUOUS MONITORING OF THE DENSITY OF CRYOGENIC LIQUIDS VIA DIELECTRIC CONSTANT MEASUREMENTS

摘要

A system has been invented for the continuous determination of density of cryogenic liquids such as LPG and LNG to within .+-. 0.1% or better using differential capacitance measurements. This system would allow the detection of incipient density inversions in storage tanks and the accurate determination of quantities transferred from ship to shore to customers.
