    摘要: A compact vibratory flowmeter (200) for measuring flow characteristics of a cement flow material at a cement 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 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 affixed 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) include a drive frequency that is less than about 200 Hertz (Hz) and a frequency ratio of the drive frequency to a fluid resonant frequency of the cement flow material that is less than about 0.8.

    摘要: A method of controlling a weld penetration profile on a workpiece (306) having an outer region and an inner region is described. The method comprises the step of applying energy to the outer region of the workpiece with a welder (302) to produce a weld pool (304). The method also comprises the steps of penetrating the workpiece (306) such that the weld pool (304) spans between the outer region and inner region, and also applying a shielding gas to the inner region at a pressure that provides a force that limits weld penetration. A corresponding apparatus is also defined.

    摘要: Die Erfindung betrifft ein Verfahren zum Betreiben eines Massendurchflußmeßgeräts, das nach dem Coriolis-Prinzip arbeitet, wobei das Massendurchflußmeßgerät ein von einem Medium durchströmtes Meßrohr (1) aufweist, das Meßrohr (1) zu einer vorbestimmten Schwingung angeregt wird und die resultierende Schwingungsantwort des Meßrohrs (1) erfaßt wird. Erfindungsgemäß ist vorgesehen, daß die für die Anregung der vorbestimmten Schwingung des Meßrohrs (1) erforderliche Antriebsleistung erfaßt wird und mittels der erfaßten Antriebsleistung das Vorliegen einer Mehrphasenströmung des durch das Meßrohr (1) strömenden Mediums detektiert wird. Auf diese Weise können Meßgenauigkeit und Zuverlässigkeit des Meßverfahrens erheblich verbessert werden.
