FIELD: physics; measuring.
SUBSTANCE: invention concerns to the measuring technics and can be used for measuring and control of motion and velocity. The method and the device for its realisation are offered. The device of measuring of the linear travels is contained by a control mean of 1 generator of the pulsing signals 2, the first amplifier 3, the electroacoustical transformer 4, an acoustic line 5, the electroacoustical receiver 6, the first damper 7 and the second damper 8, the second amplifier 9, the third amplifier 10, the first narrow-band filter 11, the second narrow-band filter 12, the first measuring instrument of intervals of time 13 and the second measuring instrument of intervals of time 14, the calculator 15.
EFFECT: accuracy and noise stability increase and also expansions of functionality.
