The research and design of a positive pressure gas meter durability test device
The newly released national standard for membrane gas meters has added a cycle method du-rability test and made clear requirements for the test conditions.This article introduces the working princi-ple and structure of a positive pressure method durability test device for gas meters,and completes a cy-cle test according to the requirements of the new national standard.The gas source capacity and pressure changes during the gas meter test process,as well as gas temperature changes during device operation,are synchronously collected and analyzed,The test results indicate that the device meets the relevant technical requirements of the new national standard durability test and can conduct durability tests on membrane gas meters.
