FIELD: measurement technology.
SUBSTANCE: this device can be used in measuring the parametres (flow rate and density) of the material, passing through the pipeline. Electronic measuring device (20) of the Coriolis flowmetre contains interface (201) to receive the first and second signals of the detector and the procession system (203) connected to the interface (201) to enable the receipt of the first and second signals of the detector, formation of the phase shift for 90 degrees from the first signal of the detector and calculation of the frequency on basis of the first signal of the detector and phase shift for 90 degrees. The system (203) is additionally made to enable the formation of sinusoidal and cosine signals using the frequency of quadrature demodulation of the first signal of the detector and second signal of the detector using sinusoidal and cosine signals to determine the phase difference.
EFFECT: invention improves the accuracy of the measurement of two-phase liquid flows with solid inclusions and air bells.
