<P>PROBLEM TO BE SOLVED: To provide a compact vibratory flowmeter (200) for measuring the flow characteristics of a cement flow material at a cement flow material pressure of greater than about 10 pounds-per-square-inch (psi). <P>SOLUTION: The compact vibratory flowmeter (200) includes at least two pickoff sensors (308) and a driver (309). The compact vibratory flowmeter (200) further includes one or more flow conduits (301). The at least two pickoff sensors (308) are attached to the one or more flow conduits (301) and the driver (309) is configured to vibrate the one or more flow conduits (301). The one or more flow conduits (301) have a drive frequency of less than about 200 Hertz (Hz), and a frequency ratio of the drive frequency to a fluid resonant frequency of the cement flow material is less than about 0.8. <P>COPYRIGHT: (C)2012,JPO&INPIT |
