On radiowave resonator method of measurement of physical properties of liquids with dielectric losses

The method of measurement of physical properties of liquids with dielectric losses has been considered. It is based on quality determination of radiofrequency/microwave resonators being sensors of physical properties. The features of this method are excitation of frequency-modulated electromagnetic oscillation in a resonator, measurement of maximal and minimal values of their amplitudes and determination of a physical property through ratio between these amplitudes.
