摘要：A method of detecting a malfunction or failure of a pressure regulator in acorrosive or reactive gas distribution system while in use involves continuously measuringor monitoring the output pressure of the pressure regulator, both in the presence andthe absence of gas flow. The onset of a malfunction of the pressure regulator can bepredicted when the differential output pressure between flowing and non-flowing gasfluctuates highly and increases gradually. Failure of the pressure regulator or of the totalsystem is detected when the differential output pressure in the presence and absence offlowing gas exceeds some experimentally determined value.
