  • Patent number: 3964317
    Abstract: A densimeter utilizes a low mass, neutral buoyancy float in association with a precision transducer which sense the deviation of the float position from a fixed neutral point corresponding to a predetermined fluid density within a range of fluid densities to be measured. The sensor output is accumulated and digitally added to a number corresponding to the predetermined density to thereby form an accurate representation of the fluid density.
