Abstract
This paper proposes an architecture of a conditioning circuit for dual-modality wire-mesh sensors, applied to multiphase flow measuring. The proposed circuit topology uses an AC-based impedance measurement technique, and is able to process signals from a 4×4 wire-mesh structure, performing an I/Q demodulation for the direct extraction of fluid permittivity and conductivity values. System-level considerations are taken into account to derive the requirements for the main circuit blocks, which are aimed to be integrated on standard CMOS technology.
