FIELD: chemical engineering. SUBSTANCE: device has electroacoustic unit, amplifier unit, exciting impulse oscillator, temporary selector unit, control unit, saving selection unit, alphanumeric printer, multiplexor, ROM, subtraction and comparison units and indicator unit. Electroacoustic unit output is connected to amplifier unit input and its input is connected to the exciting impulse oscillator. Amplifier output is connected to temporary selector unit input. Amplifier input is connected to temporary selector unit input. Control unit input is connected to comparison unit output. Control unit outputs are connected to the first inputs of the exciting impulse oscillator, temporary selector unit, saving selection unit, multiplexor, ROM, comparison unit. Comparison unit output is connected to the alphanumeric printer. Alphanumeric printer output is connected via the multivibrator to the second ROM input and the first subtraction unit input. The second subtraction unit input is connected to the ROM output and its output is connected to the second comparison unit input. The comparison unit output is connected to the indicator unit. EFFECT: no dependency of measurement results of reservoir parameters like thickness, surface roughness. 2 cl, 3 dwg
