The intelligence system of monitoring of technological parameters of the water pipeline is in-process observed, allowing to lead an estimate of reliability of water supply systems and optimisation of plots of repair
Keywords: Intelligence system, monitoring, structure, technological parameters, the water pipeline, reliability, repair
In operation the case when the cylindrical pipe is not completely filled by water is viewed, the ultrasonic radiator is located on a shell of a water pipe. It is shown, that for the given case, it is expedient to view the symmetrical and assymetric modes of distribution of an ultrasonic wave.

In operation the case when the radiant of an acoustic signal is in a composite cylindrical pipe is viewed. It is shown, that at transition of a pipe of one diameter in a pipe of other diameter, it is expedient to apply modal representation of an acoustic wave to each site of a pipe.
