    Abstract: A steam measurement system includes a Coriolis flowmeter (440, 540, 640) associated with a vibratable flowtube (410, 510, 610) to receive a flow of wet steam. A first sensor is associated with the flowtube to relay information about a motion of the flowtube by way of a first sensor signal. A second sensor determines a property of the flow and relays the property by way of a second sensor signal. A computing device (440, 540, 640) receives the first and second sensor signals and is configured to calculate a steam quality of the flow from the first and second sensor signals (700). The computing device also may calculate the total heat energy flow rate of the flow (800). Other implementations may include a full or partial separator (920) to separate the flow of wet steam into a substantially gas flow and a substantially liquid flow, and a second Coriolis meter (960a, 960b).

    Abstract: Techniques for measuring a density of a liquid within a fluid that includes both a liquid and a gas are described. A pressure of the fluid oscillates according to a time-varying function, which causes a density of the fluid also to oscillate according to the same time-varying function (235, 404). A resulting pressure signal (302) and density signal (304) are analyzed to extract at least a first and second pressure value (225, 245) and at least a first and second density value (205, 240), (410), where the first pressure and density values occur at a first time, and the second pressure and density values occur at a second time. Then, the liquid density is calculated from the first and second pressure and density values (250, 414). As a result, the liquid density may be calculated quickly and easily, with a minimum of effort on the part of an operator, and without requiring disruption of other measurement processes associate with the flowtube.

    Abstract: A flowmeter (200) is disclosed. The flowmeter (200) includes a vibratable flowtube (215), and a driver (210) connected to the flowtube (215) that is operable to impart motion to the flowtube (215). A sensor (205) is connected to the flowtube (215) and is operable to sense the motion of the flowtube (215) and generate a sensor signal. A controller (104) is connected to receive the sensor signal. The controller (104) is operable to determine a first flow rate of a first phase within a two-phase flow through the flowtube and determine a second flow rate of a second phase within the two-phase flow.

    Abstract: Descriptions are provided for implementing flowmeter zeroing techniques. In operating a flowmeter (200), it may be the case that, if not properly calibrated, the flowmeter (200) will produce erroneous measurements, e.g., will indicate a non-zero flow during a period of zero flow. By determining a magnitude of such erroneous measurements, calibration values (402, 404, 406) may be determined (602), which may later be used to adjust a measurement that is output by the flowmeter (200) and thereby improve an accuracy of the flowmeter (200). Such calibration values (402, 404, 406) may be determined for a plurality of operational conditions associated with the flowmeter, such as densities of materials being measured, and/or configurations of flow elements associated with transporting material to the flowmeter (604, 606). Then, the calibration values (402, 404, 406) may be correlated with the relevant operational conditions, and stored for later use (608). In this way, during an actual operation (618) of the flowmeter (200), a number of calibration values may be made available, and an optimal calibration value may be selected (612) for an existing operational condition of the flowmeter (200).
