Abstract
The article presents the results of checking mathematical model of the created decreasing pressure effusion computer gas density analyzer. Operating principle of a decreasing pressure effusion gas density analyzers is based on measuring the outflow time of the analyzed gas certain volume through a microdiaphragm. A generalized scheme of such analyzers and their operation are described in article. Initial equations of the mathematical model, the assumptions and the results of the development of the mathematical model are presented. The created experimental setup for testing the developed mathematical model and its operation also are described. The mathematical model was tested in the course of numerous experiments on this facility for a number of gases. Studies have also been performed to assess the effect of temperature on the measurement result. The results of the mathematical model test are presented in the article. The results of experimental studies were compared with the calculated data obtained on the basis of a mathematical model. As a result, the error of the mathematical model of the decreasing pressure effusion gas density analyzers was determined and conclusions were made about its adequacy and possible further use for designing and calculating decreasing pressure effusion gas density analyzers.
