Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume (Thank you, Wikipedia).  Often the reference substance for liquids is pure water at a temperature of +4°C, which is assigned a value of 1.0. The specific gravity measurement is used throughout many industries as a measure of concentration in a solution. An example would be the concentration of sugar in a solution of water and sugar. 

For purposes of process analysis, an instrument providing continuous measurement is generally advantageous since its operation accommodates the changing nature of the process. One device employs two tubes and a calibrated float to provide a continuous display of a liquid's specific gravity. Liquid from the process fluid sample line enters the bottom of the inner tube containing the float. A very small sample flow rate is needed. The float is calibrated for the subject process liquid and has a reference scale from which the specific gravity is manually read. The sample fluid overflows the inner tube, collecting in the outer tube where it is drained away. The continuous, though small, flow of sample liquid enables each reading to reflect the current process condition.

This simple and effective instrument provides accurate measurement and requires little maintenance. Share all your process fluid analysis challenges with application specialists. Combine your process knowledge with their product application expertise to develop the most effective solutions.
