1. A meter electronics (20) for determining a vapor pressure using a vapor pressure meter factor, the meter electronics (20) comprising:
a processing system (200) communicatively coupled to a meter assembly (10), the processing system (200) being configured to:
provide a drive signal to the meter assembly (10) having a fluid;
measure a drive gain of the drive signal provided to the meter assembly (10); and
determine a vapor pressure value of the fluid based on a previously determined relationship between the drive gain and a reference gas-liquid ratio.
