Even though the merits of cryogenic fluid metering are well known, the means of accomplishing this end are not so well established. Flow measurement is useful in those applications that involve gases or liquids in processes which either produce or use cryogenic fluids. It is useful in custody transfer at the point of sale, where measurement of the fluid transferred forms the basis of customer billing. It is useful in the ground test and the in-flight performance testing of rockets and missiles. The measurement of cryogenic fluid flow is a difficult and sometimes exasperating task. In large part, this is due to the very nature of the fluids being measured. Cryogenic fluids generally exist as saturated fluids. Pipe runs are generally short. Differential pressure measurement associated with head-type meters is often difficult. Because of the extreme low temperatures involved, thermal effects are significant. Pressure drop through a flowmeter must be kept low to avoid superheating the fluid. Cryogenic fluids provide little or no lubrication for meter bearings.
