发明名称 SONIC METHOD AND MEANS FOR DETERMINATION OF SOLUTION CONCENTRATIONS
摘要 This invention relates to a method of determining the chemical concentration of a solution. More particularly, the invention relates to determining the chemical concentration of a solution by measuring the speed of sound transmission, the temperature, and the hydrostatic pressure of the solution, and conveying these measurements to an analog computer wherein the chemical concentration is ascertained from preestablished empirical formulas.
