FIELD: machine building.
SUBSTANCE: tubular structure consists of sequence of tubular sections butt connected by means of connecting device. At least majority of tubular sections has axial length at least of value X between connecting devices. At least majority of the connecting devices has axial length not exceeding value x. Also, X is considerably bigger, than x. Distance N for transmission of data is at least equal to 10 X. The device is equipped with a facility for transmitting acoustic signals in form of tone from the first position along a structure. Tones have chosen wave guide mode with length of wave at least 2x. At initial propagation each tone has at least temporary length not more, than multiple X/C and in essence less, than 2N/C.The device additionally has a facility for determination of signals in the second position in the structure distant along the structure from the first position at the said distance N.
EFFECT: overcoming problem of interference related to Brillouin dispersion without excessive energy output.
