A refined method has been developed for leakage detection of long petrol product pipelines.
The new method is based on the steady state hydraulic model of a variable diameter
pipeline with high geodetic differences operated in multi-batch delivery mode (more
then one type of products are transported at the same time). With the help of this
new method it is possible to recognize and localize even a low intensity taping which
do not induce significant pressure waves, and so, can not be discovered by acoustic
monitoring methods.
