Abstract
This invention is related to the measurement of flow rates and component fractions of individual phases of a composite fluid. More particularly, the invention is directed toward apparatus and methods for determining the volumetric flow rate or mass flow of one or more phases of a fluid by measuring the activity, as a function of time, of one or more specific radioactive isotopes affected by a specific phase of the flowing fluid stream. Radioactive phase isotope material is deposited upon one or more inserts, and each deposition of phase isotope material is coated with a corresponding phase coating. Each phase isotope and corresponding phase coating is soluble in only one phase of the multi-phase flow. The inserts are then inserted into the multi-phase flow, and the time required for each flow phase to wash the corresponding phase coating from the insert is measured by the release of the corresponding phase isotope into the flow stream. Phase flow parameters of interest are then computed from the measured phase release times.
