METHOD AND DEVICE FOR CHECKING LEAKTIGHTNESS AND/OR DETECTING LEAKS IN TANKS

摘要

The invention is for use with 'empty' and degassed' tanks for storing liquid oil products and chemicals. It comprises three parts: 1) Selecting the right tools and devices for carrying out this type of test, guaranteeing leak detection at a rate of 100 ml/h, and for sending the signals from the tools to a portable computer. 2) Implementing and using signal conditioning methods and methods of analysis in the time domain and frequency domain, on pressure signals acquired during the performance of this type of test. 3) Developing software, based on the conclusions drawn from the application of the above methods, to a variety of tests, which can work 'in real time' and automatically output a diagnosis indicating leaktightness or the presence of leaks.
