    Enraf licensed the exclusive rights for manufacture and service of the DENSITRAK® meter to Analytical Flow Technologies in March 2010. Analytical Flow Technologies is owned and operated by Paul Heinritz, who has a long relationship with the DENSITRAK® Densitometer in which he ran the DENSITRAK® product line for Calibron Systems, Inc.

  • Page 9: Density Equations

    D625 Users Manual DENSITY EQUATIONS A simple definition for Density (for a homogeneous object) is the mass of the object divided by the volume of the object. Thus, common units of fluid density are grams per cubic centimeter, kilograms per cubic meter, and pounds per cubic foot. The hydrometer is probably the most common device used to measure fluid density in which it measures the volume displaced by an object of known mass.
