PCT No. PCT/SU88/00098 Sec. 371 Date Dec. 13, 1989 Sec. 102(e) Date Dec. 13, 1989 PCT Filed Apr. 25, 1988 PCT Pub. No. WO89/10559 PCT Pub. Date Nov. 2, 1989.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 (2) along the wall of a measuring vessel (1) and through the test medium (2) 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 (1), an emitting ultrasonic converter (4), a receiving ultrasonic converter (7) which are mounted on the wall of the measuring vessel (1) separated by forming prisms (5 and 6), a pulse generator (3), amplifiers (8 and 18), a source (16) of gamma-radiation and a receiver (17) of gamma-radiation which are mounted on the walls of the measuring vessel (1), a multivibrator (9), a one-shot multivibrator (10), a delay line (11), a square pulse generator (12), a gating unit (13), smoothing filters (14, 19), an amplitude detector (15), and a data processing assembly (20) comprising units (21 and 22) for setting standard values, two subtraction circuits (23, 24) and a dividing circuit (25). |
