Abstract

The paper deals with the analytical correlation between the obtained polarization voltage and the dielectric fluid velocity through the circular cross section of the polarization transducer. The aim is verification of the analytical results by the comparison of the analytically calculated voltage between the electrodes and its numerically obtained value applying FEM (QuickField 5.6). As the result of the inverse problem solution (Response Surface Methodology, Design of Experiments and Flexible Tolerance Method) the optimal constructive parameters and the exciting magnetic field distribution are determined guarantying maximal outgoing signal and consequently increasing the device sensitivity.
