ACOUSTIC MEASURING CHANNEL Russian patent published in 2021 - IPC F17D5/02 G21C17/17 

FIELD: nuclear energy.

SUBSTANCE: invention relates to the field of nuclear energy and can be used, in particular, in systems for detecting, locating and determining the amount of coolant leakage from pipelines and equipment of water-water energetic reactors (WWER). The acoustic measuring channel contains an acoustic sensor 1 connected by means of a connection node with an analog communication line 2 connected to the input of an amplifier-converter 12, the output of which is connected to the input of an information device 13 by means of a digital communication line 16. The channel is equipped with an acoustic communication line, including the first and second waveguides 4, 5 connected to each other by means of the first quick-release connector 8 and connected to each other by means of the second quick-release connector 11, half-clamps 6 and 7 for tight installation on the controlled pipeline 10. The first waveguide 4 is rigidly connected to the acoustic sensor 1, the second waveguide 5 is rigidly connected to one of the half-clamps 6, and the connection node is made in the form of a detachable connector 3, the instrument part of which is connected to the acoustic sensor 1, and the cable part is connected to the analog communication line 2.

EFFECT: increase in the safety of operation of the measuring channel, to reduction in the dose loads on the operating personnel when servicing the measuring channel.
