A 1D numerical model of a straight-tube Coriolis meter has been implemented and used to generate a simple and intuitive parametric relationship to predict sensitivity. This model is intended to aid the design of such meters and avoid the need to run a large number of time-consuming simulations. Three parameters were identified as being instrumental in determining the sensitivity of a meter: dimensionless bending stiffness ($\tilde{\Sigma }$), proximity to the Euler buckling limit ($\tilde{R}$) and the dimensionless sensor spacing ($\tilde{\chi }$). Parametric relationships for sensitivity (dimensionless time-lag) and natural frequency were developed. These equations allow for the complete and rapid design of a straight-tube Coriolis meter with insignificant computational effort. The parametric model was validated against 11 experimental data sets, covering a range of flow conditions, tensions and materials. In all cases, the parametric model performed well, reporting a typical error of 2 to 5%.

直管科里奥利仪表的一维数值模型已实现，并用于生成简单直观的参数关系以预测灵敏度。该模型旨在帮助设计此类仪表，并避免了运行大量耗时的仿真的需求。确定了三个参数可用于确定仪表的灵敏度：无量纲的弯曲刚度（$\tilde{\Sigma }$），接近欧拉屈曲极限（$\widetilde{\mathrm{[R}}$）和无因次传感器间距（$\tilde{\chi }$）。建立了灵敏度（无量纲时滞）和固有频率的参数关系。这些方程式可以用很少的计算量就可以完整，快速地设计出直管式科里奥利流量计。该参数模型针对11个实验数据集进行了验证，涵盖了各种流动条件，张力和材料。在所有情况下，参数模型均表现良好，报告的典型误差为2％至5％。
