This diploma presents my work on CALMS project, which is specialized platform for leak detection, repair and improvement in compressed air system quality. My task was to find the characteristics of new ultrasound sensor. Beside that, I was also looking into leak quantification and how to calculate leak flow using ultrasound instruments readings and compressed air system pressure.
In theoretical part of diploma there are basic informations of compressed air usage, leak theory, CALMS project and description of some ultrasound instruments.
In the first section of practical part there is description of making of the leak simulation device, with which all the tests were made.
In the second part tests and data collection are described. Program was made in MATLAB environment for purpose of analysis of collected data and generation of calculation table. Program calculates approximation of leak flow using sound pressure level and system pressure level.
Lastly, I made on site testing with ultrasound instrument. Beside that, I made practical comparison between ultrasound instrument UE15000 and NL camera. NL camera is ultrasound acoustic camera that is new technology on leak detection market.
