FIELD: physics.
SUBSTANCE: acoustic sensors are made in form of a parametric converter consisting of a microprocessor, pumping signal former, parametric radiating channel, receiving channel, where the radiating channel contains a pumping signal former and a multielement mosaic antenna, the receiving channel includes an antenna made in form of an array of piezoceramic n sound receivers with a cylindrical shape, each having separate sealing and mounted on a board fitted with an acoustic screen. The n receivers lying next to each other are displaced from each other in the vertical and horizontal planes. The housing of the antenna is closed by a sound transparent membrane. There is an additional hydroacoustic communication channel.
EFFECT: high reliability of determining points of leakage of a transported product from main pipelines.
