Method of monitoring parameters of solid phase of suspension and device therefor

Abstract

This invention relates to measurements of characteristics of a comminuted material by an ultrasonic method. The method of monitoring parameters of a solid phase of suspension comprises the steps of producing a Lamb wave and gamma-radiation and passing them respectively through a test medium along the wall of a measuring vessel and through the test medium placed therein, measuring the amplitude of the Lamb wave and the intensity of gamma-radiation, while using, as the test medium, separately a standard liquid and the analyzed suspension to find the parameters of the solid phase of suspension by way of the ratio of the measured values. A device realizing this method comprises a measuring vessel. an emitting ultrasonic converter, a receiving ultrasonic converter which are mounted on the wall of the measuring vessel separated by forming prisms, a pulse generator, amplifiers, a source of gamma-radiation and a receiver of gamma-radiation which are mounted on the walls of the measuring vessel, a multivibrator, a one-shot multivibrator, a delay line, a square pulse generator, a gating unit, smoothing filters, an amplitude detector, and a data processing assembly comprising units for setting standard values, two subtraction circuits and a dividing circuit.
