Abstract
The present invention provides a method and apparatus for the real-time measurement of volumetric flow rates of the water/oil/gas fractions of a multiphase (water/oil/gas) flow in a pipe without the requirement of the separation of the gas and liquids. A number of material property sensors, multiphase flow-rate sensors, and temperature sensors are utilized. The water, oil or gas properties in a small region are determined instantaneously by a number of material property sensors based on the viscosity differences of the individual phases of the multiphase fluid at a certain temperature. Adding the volumetric flow fractions of the same phases in the small regions, the volumetric flow of the individual phases of the multiphase flow during a known time interval can be obtained.
