DIRECT PULSE METHODS OF MEASUREMENT OF SPEED OF THE SOUND IN THE LIQUID
Errors of direct pulse methods of measurement of speed of a sound in a liquid are considered. The special attention is turned on perspective pulse methods with use time-flying and cylindrical piezoelectric acoustic systems with repeated reflexion of impulses. Originality of the method of sound speed measurement in water consists in use of the acoustic base executed as the piezoelectric cylinder. Working distance of acoustic base is internal diameter of the cylinder. The basic functional devices are carried out on digital elements.
