A meter electronics () for determining a vapor pressure using a vapor pressure meter factor is provided. The meter electronics () comprises a processing system () communicatively coupled to a meter assembly (). The processing system () is configured to provide a drive signal to the meter assembly () having a fluid, measure a drive gain of the drive signal provided to the meter assembly (), and determine the vapor pressure of the fluid based on a previously determined relationship between the drive gain and a reference gas-liquid ratio.

Determining a vapor pressure using a vapor pressure meter factor

A system () for using a vapor pressure to determine a concentration of a component in a multi-component fluid is provided. The system () includes an electronics () communicatively coupled to a transducer () configured to sense a multi-component fluid. The electronics () is configured to determine a first vapor pressure, the first vapor pressure being a vapor pressure of a first component of the multi-component fluid, determine a second vapor pressure, the second vapor pressure being a vapor pressure of a second component of the multi-component fluid, and determine a multi-component vapor pressure, the multi-component vapor pressure being a vapor pressure of the multi-component fluid. The electronics () is also configured to determine a concentration of at least one of the first component and the second component based on the multi-component vapor pressure, the first vapor pressure, and the second vapor pressure.

Using vapor pressure to determine concentrations of components in a multi-component fluid

A meter electronics () for using a density measurement of a fluid to verify a vapor pressure is provided. The meter electronics () includes a processing system () communicatively coupled to a meter assembly () having the fluid, the processing system () is configured to determine a vapor pressure of the fluid by detecting a phase change of the fluid in the meter assembly (), measure a density of the fluid based on a resonant frequency of the meter assembly (), derive a vapor pressure from the measured density, and compare the determined vapor pressure with the derived vapor pressure.
