  • Method and apparatus for determining acid concentration
    Patent number: 5175502
    Abstract: Acid concentrations are determined by the method and apparatus, particularly HCl acid for picking ferrous material. Specific gravity measurements are made on acid samples, diluted acid samples and water. Conductivity measurements are conducted on the diluted acid samples. The water dilution minimizes the influence of the metal salt in the sample to improve the conductivity measurements. The system calculates the acid concentration by a series of approximations using the conductivity data and the acid concentration - conductivity relationships to provide an accurate acid concentration which is easily automated by computer.
