ABSTRACT:
An apparatus and method for determining the individual mass flow rates of a multi-component flow. Individual components of the multi-component flow have different products of longitudinal relaxation time and flow velocity. Two or more arrangements of magnets and flow sensors are arranged along a pipeline. A static magnetic field is imposed on the flow. The linear movement of the flow then generates a multi-exponential gain of magnetization. By interrogating the flow at several positions, the magnetization and velocity is measured simultaneously in different positions. The multi-exponential gain of magnetization and determination of the equilibrium magnetization of each component thermal equilibrium can then be determined. The mass flow rates in the individual components can then be determined.
