METHOD FOR CONTROL OF QUALITATIVE AND QUANTITATIVE COMPOSITION OF LIQUID

摘要

The invention relates to control of liquid composition in which one experimentally determines dependence of active and reactive conductivity of solution of a reference sample of liquid under investigation on frequency of electromagnetic field in range of 50-100 Hz, with determination of volume of that solution in a carbon transducer that induces the change of polarity of reactive conductivity component, with determination of selective for controlled substance in reference sample value of field frequency at which reactive component is equal to zero at normalized limiting permitted concentration of substance. Thereafter the transducer adjusted to that volume of liquid and frequency of signal is used as a control element of automated control system at response to indicator signal at exceeding given concentration of substance at which one compares characteristics of active and reactive components to pre-studied solution of reference sample, in such a way one makes conclusion on qualitative and quantitative composition of liquid.
