Dual-modality Impedance Wire-Mesh Sensor for Investigation of Multiphase Flows

For the investigation of multiphase flows, i.e. in oil production, there are only few suitable measuring techniques. For this reason, in this paper a new multichannel complex impedance measuring system using wire-mesh sensors is presented. The novel system measures amplitude and phase components of impedance (at single frequency) and is thus able to evaluate simultaneously the conductive and the capacitive parts of a fluid (complex permittivity). In the future this system can be employed for the investigation of dynamic processes in multiphase flow. The performance in measuring amplitude and phase of a signal is evaluated. First promising results for the three-phase flow are presented.

Keywords: Complex impedance measurement; multiphase flow; wire-mesh sensor
