| Abstract: | Comparison trials and studies on small-flow measurement of civil natural gas were performed, as a result of the considerably fluctuant natural gas flow-rate and the dust and dirt it contains. Performance differences of different types of civil natural gas flowmeters were evaluated, including their accuracy grades, adaptation ability against gas flow environment and outside condition. Moreover, an intellectualized TDS swirl flowmeter being able to switch off airflow automatically, was put forward to decrease the errors of small-flow measurement effectively. Finally, optimum suggestions are proposed on how to select small-flow flowmeters which can be used for measurement of civil natural gas. |
