Abstract A method for measuring parameters of solid phase of slurries, having the following steps: forming ultra- sonic oscillations and emitting them into a fluid under study, forming Lamb waves and directing them into the wall of a vessel containing the fluid under study, forming acoustic currents and radiation pressure of a sonic radiation in the fluid under study, and measuring amplitude and length of pulses of the ultra- sonic oscillations that passed through the fluid under study and of the Lamb waves that passed through a pre- determined distance along the wall of the vessel con- taining the fluid under study with and without the ac- tion of acoustic currents and radiation pressure, the values of the amplitudes and pulse lengths being used for evaluating concentration of solid phase and of a critical particle size fraction of solid phase and concentration of a useful component in critical particle size fractions of the fluid under study. An apparatus for carrying, out the method for measuring parameters of solid phase of slurries has two measurement channels each having a series circuit including a pulse generator, an emitting ultrasonic transducer, a received pulse amplifier, and a logarithmic converter as well as a subtraction unit having inputs to which are connected outputs of logarithmic converters of both channels, and a division unit having inputs to which are connected the output of the subtraction unit and the output of the logarithmic converter of the second measurement channels.
