| Abstract: |
| This paper introduces a set of gas flow standard facilities based on combined turbine flow meters, which is newly built by Chengdu Verification Branch of National Oil and Gas Large Flow Rate Measurement Station, including the process of the standard facilities, testing requirements and results of the metering performance. The standard facilities are used for actual flow verification of the natural gas flow meter and guaranteeing the accuracy and reliability of onsite trade measurement of natural gas. By analyzing the testing data, it has confirmed that the uncertainty of standard test results is better than 0.33%. Both the repeatability and stability of test results meet the verification requirements for gas flow measuring instruments. |
