Abstract:Pipeline or cavity always exist before the pressure transducer when measuring pressure because of limitation of installation space, high temperature or complex media. The pressure measurement systems’ dynamic characteristics are often determined by the pipelines. The theoretical research progress of the pipeline dynamic characteristic is first reviewed, and the research results of factors affecting the dynamic characteristic are presented. Then the main calibration methods of pipeline are introduced, and the characteristics and using conditions of different calibration methods are analyzed. The existing problems and the further study needed in the future are finally discussed.
