    • A compact vibratory flowmeter (200) for measuring flow characteristics of a multi-phase flow material at a flow material pressure of greater than about 10 pounds-per-square-inch (psi) is provided according to an embodiment of the invention. The compact vibratory flowmeter (200) includes one or more flow conduits (301), at least two pickoff sensors (308), and a driver (309). The compact vibratory flowmeter (200) further includes a maximum water drive frequency in the one or more flow conduits (301) that is less than about 250 Hertz (Hz) and an aspect ratio (L/H) of the one or more flow conduits (301) that is greater than about 2.5. A height-to-bore ratio (H/B) of the one or more flow conduits (301) is less than about 10 and a bowed flow conduit geometry includes end bend angles of between about 120 degrees and about 170 degrees.
    • 根据本发明的实施例,提供了一种用于测量流动材料压力大于约10磅/平方英寸(psi)的多相流动材料的流动特性的紧凑型振动流量计(200)。 紧凑型振动流量计(200)包括一个或多个流动管道(301),至少两个传感器(308)和驱动器(309)。 紧凑型振动流量计(200)还包括在所述一个或多个流动管道(301)中的小于约250赫兹(Hz)的最大水驱动频率和所述一个或多个流动管道的纵横比(L / H) (301)大于约2.5。 一个或多个流动管道(301)的高度 - 孔径比(H / B)小于约10,弓形流动管道几何形状包括约120度至约170度之间的端部弯曲角度。
