Abstract Coriolis mass flowmeters are used for many applications, including as transfer standards for proficiency testing and liquified natural gas (LNG) custody transfer. We developed a model to explain the temperature dependence of a Coriolis meter down to cryogenic temperatures. As a first step, we tested our model over the narrow temperature range of 285 K to 318 K in this work. The temperature dependence predicted by the model agrees with experimental data within ± 0.08 %; the model uncertainty is 0.16 % (95 % confidence level) over the temperature range of this work. Here, basic concepts of Coriolis flowmeters will be presented, and correction coefficients will be proposed that are valid down to 5 K based on literature values of material properties.

模拟温度对科里奥利质量流量计的影响

摘要 科里奥利质量流量计用于许多应用，包括作为能力验证和液化天然气 (LNG) 贸易交接的传输标准。我们开发了一个模型来解释科里奥利仪表对低温的温度依赖性。作为第一步，我们在这项工作中在 285 K 到 318 K 的狭窄温度范围内测试了我们的模型。模型预测的温度依赖性与实验数据一致在±0.08%以内；在这项工作的温度范围内，模型不确定性为 0.16%（95% 置信水平）。在这里，将介绍科里奥利流量计的基本概念，并根据材料特性的文献值提出有效低至 5 K 的校正系数。
