The flow may be a multiphase flow which comprises fluids, and may comprise a mixture of liquids, or one or more liquids in a mixture with solids and/or gases. This invention may provide a multiphase flow metering apparatus which has a number of applications, in particular within the oil and gas exploration and production industry.

Apparatus and method are provided wherein by measuring both the electrical permittivity and the electrical conductivity of the measured multiphase fluid, the resultant amplitude and phase angle of the induced complex voltage can be analysed. The phase angle data can be analysed to provide information on the electrically conductive phase, and that information can be employed to analyse the amplitude data, in particular to use the information on the electrically conductive phase to determine the contribution to the amplitude data by the electrically non-conductive phase. This analytical technique enables the electrical permittivity of the electrically non-conductive phase to be accurately determined. By determining the degree of contribution to the complex voltage measurement by both the permittivity and the conductivity, enhanced measurement accuracy of a multiphase fluid can be achieved.
