ABSTRACT:
Method and apparatus for determining jet fuel density. A microprocessor monitors the temperature, velocity of sound and dielectric constant of a jet fuel. The microprocessor determines the type of jet fuel and the density of the fuel using data from jet fuel samples of a known density and a least-squares-fit of the test data.
