FIELD: automatic-control systems. SUBSTANCE: method allows filling of information signal with count pulses having relatively large pulse repetition period without reducing the truth of measurement results caused by temperature instability of probing pulse distribution medium. Device has two ultrasonic transducers positioned along line parallel to surface of object to be checked, acoustic pulse generator, amplifier-former, five electronic switches, two triggers, single-shot multivibrator, univibrator, two counters, and two diodes. EFFECT: higher measurement results. 2 cl, 2 dwg
