This work aims to model a device enabling a useful and accurate electromagnetic characterization of fluids. The device developed is based on a non destructive testing (NDT) control technique evolving the eddy currents induced in the fluid to be characterized. The finite element method was used in the modeling to determine the conductivity of the fluid from the induced eddy current. In addition, an experimental device has been built. It consists of an absolute probe where the fluid control is made by determining its electrical conductivity by measuring the variations of the fluid impedance as a function of the applied voltage frequency. Good agreements are found between modeling results and experimental measurements. An inverse model that converges after only 7 iterations has been also proposed for the determination of the conductivity of fluids by the use of theoretical and experimental measurements.

Niniejsza praca ma na celu zamodelowanie urządzenia umożliwiającego użyteczną i dokładną charakterystykę elektromagnetyczną płynów. Opracowane urządzenie opiera się na technice kontroli badań nieniszczących (NDT), która rozwija prądy wirowe indukowane w scharakteryzowanym płynie. W modelowaniu wykorzystano metodę elementów skończonych do wyznaczenia przewodności płynu z indukowanych prądów wirowych. Ponadto zbudowano eksperymentalne urządzenie. Składa się z sondy absolutnej, w której kontrola płynu odbywa się poprzez określenie jego przewodności elektrycznej poprzez pomiar zmian impedancji płynu w funkcji przyłożonej częstotliwości napięcia. Stwierdzono dobrą zgodność między wynikami modelowania a pomiarami eksperymentalnymi. Zaproponowano również model odwrotny, który zbiega się już po 7 iteracjach, do wyznaczania przewodnictwa płynów za pomocą pomiarów teoretycznych i eksperymentalnych.
