ABSTRACT:
A method and apparatus for monitoring fluid flow in a pipe or at an exit of the pipe and detecting a fault. The system includes an acoustic generator which is activated by the fluid flowing in the pipe or at the exit of the pipe. The acoustic generator sends an acoustic signal, which may have a distinctive signature, through the fluid flowing in the pipe. The acoustic signal is received by a remote upstream acoustic receiver and is translated into an electric signal supplied to a signal processor.
