METER ELECTRONICS AND METHODS FOR RAPIDLY DETERMINING A MASS FRACTION OF A MULTI-PHASE FROM A CORIOLIS FLOW METER SIGNAL

摘要

The meter electronics (20) for determining a mass fraction of flow components in a flow material flowing through a flow meter is provided according to the present invention. The meter electronics 20 includes a processing system 203 to communicate with the interface 201 and the interface for receiving a frequency response of the flow material. The processing system is configured to receive the frequency response from the interface 201, separating the frequency response into at least a gas frequency component and the fluid frequency component. The processing system 203 is determining the overall density from the frequency response, and further configured to determine a gas density from the gas frequency component. The processing system 203 is further configured to determine 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 is further configured to determine the mass fraction from the product of the ratio obtained by dividing the density of the gas in the total density of the gas in the void fraction. ; Mass flow, Coriolis meter, the mass fraction
