METHOD OF MEASURING ELECTROCONDUCTIVITY OF ELECTROLYTE SOLUTION Russian patent published in 2014 - IPC G01N27/06 

FIELD: chemistry.

SUBSTANCE: method of measuring electroconductivity of electrolyte solution, located in liquid contour of first and second primary converters with drive winding, included into circuit of frequency generator, consists in registering outlet signal of voltage of measurement channels depending on solution concentration on condition that measurement is carried out in stabilised temperature field. In accordance with the invention level of sensitivity of first and second primary converters is determined by voltage value at outlet transformer of measurement channel depending on concentration of solution located in liquid contour, its temperature, and is in functional dependence on voltage and frequency of energy source of drive winding of feeding transformer. Measurement of solution electroconductivity is carried out with switching on reactor to operation frequency, determined in experimental analysis of solutions as optimal for analysed range of solution concentration; with registration of value of outlet signal of voltage of measurement channels, which is used to determine solution electroconductivity.

EFFECT: increasing accuracy of electroconductivity measuring in wide range of electrolyte solutions concentration.
