由于历史原因,压缩天然气加气机从1998年在我国开始投入使用时,一直采用体积(立方米,m3)作为贸易结算单位。由于当时加气机产品并不成熟,性能也不稳定,各生产厂家都在摸索,随着高压天然气计量技术的日益发展,气体质量流量计以其稳定的工作状态和高性价比等特点运用在加气机的计量单元,使加气机整体水平得到了大大提高,因此,2003年以后国内的加气机均采用了以科里奥利质量流量计为核心部件的计量单元。科里奥利质量流量计的主要工作
Due to historical reasons, when the CNG filling machine started to be used in our country in 1998, the volume (m3, m3) has been adopted as the trade settlement unit. Because at that time filling machine products are not mature, the performance is not stable, the manufacturers are groping, with the growing development of high-pressure gas measurement technology, gas mass flow meter with its stable working conditions and cost-effective features such as the use of Canada The measuring unit of the gas machine, so that the overall level of the gasifier has been greatly improved, therefore, after 2003, the domestic gasifier uses a Coriolis mass flowmeter as the core components of the measuring unit. Coriolis mass flowmeter’s main work
