Abstract
Official abstract text for this publication.
A method for compensating for changes in a property of water in a multiphase fluid during analysis of the multiphase fluid is provided. In one embodiment, the method includes providing a multiphase flow meter system configured to emit and detect nuclear radiation, to emit and detect microwave radiation, and to analyze a received multiphase fluid. The method can also include measuring a temperature and a microwave complex permittivity of the multiphase fluid. Further, the method includes compensating for changes in the property of water in the multiphase fluid during analysis of the multiphase fluid by using an empirical transformation between the fluid temperatures, microwave complex permittivities and nuclear mass attenuation coefficients for mixtures of different waters expected to be produced and received by the multiphase flow meter system. Additional systems, devices, and methods are also disclosed.
