文摘This paper uses a reduced model for simulating propagation of acoustic signals in fluid filled pipelines. The study allows a better understanding of the multipath environment found in a pipeline system with the goal of finding optimum solutions for monitoring the pipeline integrity. Data provided both from the simplified model and from an equivalent experimental test rig are implemented using classical time delay estimation algorithms. It is observed an improved accuracy when closing gradually the pipeline end as a result of cancelling the multipath effect at the system＇s terminal.
