description FIELD: physics. ^ SUBSTANCE: method involves excitation of continuous harmonic oscillation of vibratory converter inserted into the measured medium, measurement of medium temperature, as well as measurement of output signal of vibratory converter followed with calculation of density and viscosity. Output signal of vibratory converter is sampled for driving frequency period. Sample data are controlled thus resulting in automatic amplification control and rated sample data then used to calculate Fourier transform coefficients for the first signal harmonic. These coefficients are used to control noise level, search of resonance zone wherein resonant frequencies of preset phase shift is captured and kept. Related device for method implementation contains signalling processor 1, programmed frequency synthesiser 2, power amplifier 3, vibratory density converter 4, amplifier 5 of programmed amplification constant, temperature sensor 6, transceiver 7 and input-output 8. ^ EFFECT: higher accuracy and noise stability, extended application and enhancement. ^ 5 cl, 1 dwg
