Abstract
A method and apparatus for improving the accuracy of fuel flow meters by compensating for the presence of vapor bubbles generated within the flow meter. The method comprises measuring the temperature of the fuel flowing through the meter and using an algorithm or static lookup table to determine a vapor compensation factor based on that temperature. Because the tendency of fuel to vaporize depends largely on seasonal variations in fuel temperature, applying a temperature-dependent vapor compensation factor promotes year-round accuracy of the flow meter output.
