| titleOfInvention | Ultrasonic device for measuring physical characteristics of materials |
| abstract | This invention relates to a non-destructive testing technique. The aim of the invention is to improve the measurement accuracy. A pyramid 1 with dihedral angles with a larger base of 45 ° is mounted on the surface of the controlled substance 5 with a combined direct ultrasonic transducer 2 located in the center of the smaller base of the pyramid and separate direct transducers 3 and 4 placed on the opposite sides of the pyramid. Transducers 2 and 3 emit ultrasonic waves into the pyramid. Transducers 2 and 4 receive ultrasonic waves reflected from the pyramid-controlled substance boundary normally and at an angle and falling normally on the working surfaces of these transducers, which increases the accuracy of the measurement of the amplitudes of the reflected waves, which are used to determine the ultrasound propagation speed, density and adiabatic compressibility factor controlled substance. 1 il. |
