天然气密度

通过应用振动式密度计试验研究，在国内建立起一种天然气密度在线测量的新方法。

A new method , on-line measurement of the density of natural gas , has been established by researching on vibrating element density transducer tests .

其特点是不需要测量天然气中组分含量，天然气密度可溯源到频率。

The characteristic is not to analyze the components of natural gas , the density of natural gas can be traced to the frequency .
