FIELD: physics.
SUBSTANCE: essence of the invention is that device for determining the physical properties of inclusions in a micro-inhomogeneous liquid medium consists of an acoustic system including a bar, at opposite ends at an angle of 45° reversible transducer and a scattering receiver are installed to its axis, connected to the hardware complex, however, the converters have a narrowly directed characteristic in the mode of radiation and reception and are installed in such a way that their directivity characteristics intersect in one plane at an angle π/2, and the hardware complex includes a radiation path, a path for receiving backscatter signals at an angle π, path of reception of scattering signals at an angle π/2 and a system for recording and processing the results obtained, containing a two-channel ADC and a computer, radiation path includes a sound pulse generator that is connected in series with a power amplifier and an electronic signal switch, the first output of which is connected to a reversible transducer of the measuring acoustic system, and the second with the input of the amplifier of the path for receiving backscatter signals, the output of which is connected to the input of the peak detector, the output of which is connected to the first input of the ADC of the data recording and processing system, receiving transducer is connected to the input of the amplifier of the path for receiving scattering signals at an angle π/2, the output of which is connected to the input of the second peak detector, the output of which is connected to the second input of the ADC of the registration and processing system.
EFFECT: providing the possibility of determining the physical properties of inclusions in a micro-inhomogeneous fluid, namely the density, compressibility of micro-inclusions and the speed of sound inside the inclusions contained in the micro-inhomogeneous liquid.
