摘要： Meter electronics (20) for determining a mass fraction of flow components in a flow material flowing is provided according to an embodiment of the invention. The meter electronics (20) include an interface (201) for receiving a frequency response of the flow material and a processing system (203). The processing system (203) receives the frequency response from the interface (201) and breaks out the frequency response into at least a gas frequency component and a fluid frequency component. The processing system (203) determines an overall density from the frequency response and determines a gas density from the gas frequency component. The processing system (203) determines the void fraction of gas from the frequency response and one or more of the gas frequency component and the fluid frequency component. The processing system (203) determines the mass fraction from the void fraction of gas multiplied by a ratio of the gas density divided by the overall density.

摘要： An analog-to-digital conversion stage (300) includes three or more ADCs (303, 305, 307) that receive two or more analog signals, generate a first digitized signal from a first analog signal, generate at least a second digitized signal from at least a second analog signal to create two or more digitized signals, and generate one or more redundant digitized signals from the two or more analog signals. The one or more redundant digitized signals are generated substantially in parallel with the two or more digitized signals. A processing device (330) generates a phase drift value from a phase difference between a redundant digitized signal of the one or more redundant digitized signals and a corresponding digitized signal of the two or more digitized signals and compensates the corresponding digitized signal using the one or more phase drift values.
