SYSTEM FOR DETECTING LEAKS IN SINGLE PHASE AND MULTIPHASE FLUID TRANSPORT PIPELINES

摘要

This patents refers to a system developed for detecting leaks in single-phase and multiphase fluid transport pipelines characterized by use measurements cells (3), sensors (4), locals processors (5) and neural models, where the measuring sensors (4) and the measurement cells (3) are installed at a number of locations along the pipeline with the purpose of monitoring the characteristic leak and normal operational pipeline transient waveforms. The local processors (5) are responsible for obtaining and sampling the signals supplied by the sensors (4), as well as their pre-processing, to make them compatible with the inputs to the neural model, this are associated to dynamic memory banks for analyzing the signals supplied by the sensors with the aim of emitting an alarm in the event that waveforms with the characteristics of a leak are detected. The local processors (5) are necessaries to implement and execute the neural models and, in the event that a leak is detected, carry out the localization calculations based on the different propagation velocities of the fluid dynamic transient caused by the leak. The system use of a communications network for transmitting data between the local processors with the aim of comparing the alarms originating from the local processors (5).
