1. A density compensating float for indicating the quantity of fluid in a tank substantially independent of the density of the fluid, comprising:

  • a float member which includes at least a portion thereof having predetermined volumetric grading along a dimension thereof, said volumetric grading related to the density variation of said fluid for maintaining said float member in a substantially constant floatation position relative to said tank independent of changes in density for a given quantity of said fluid;

    said portion of said float member comprising four discrete volumetric segments positioned along an axis of said float member, said segments including;

    a first segment having first and second ends and having a first diameter between said first and second ends thereof;

    a second segment having first and second ends said first end thereof being connected to said second end of said first segment and having a diameter equal to said first diameter, said second end thereof having a second diameter less than said first diameter;

    a third segment having first and second ends, said first end thereof being connected to said second end of said second segment and having a diameter equal to said second diameter, said second end thereof having a third diameter greater than said second diameter and less than said first diameter; and

    a fourth segment having first and second ends, said first end thereof being connected to said second end of said third segment and having a diameter equal to said third diameter between said first and second ends thereof; and

    means for supporting said float member in said tank.
