Abstract
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 Θ of between about 120 degrees and about 170 degrees.
