摘要：

We classify methods for the determination of the total concentration of salts in water. We developed variants of an acoustic method for express-control of the concentration of salts in water when results did not depend on a variation in the temperature. Measurement and functional conversion of multiply reflected signals along the measuring base in reference liquids and liquids under investigation are the foundations of there variants. We proposed principles of construction and the structure of a three-channel microprocessor system, which allows us to automatize processes of measurement and calibration, improve sensitivity, and extend the measurement range.
