Abstract
FIELD: measurement technology, measurement of concentration of liquid media, specifically, measurement of concentration of oil in highly flooded emulsions. SUBSTANCE: invention can find use in systems of automatization of processes of oil production and refining. Method is based on relation of electric conductance of medium and content of oil in it and involves joint determination of electric conductance and ambient temperature. Specific feature of method consists in additional measurement of damping of SHF radiation and in finding of sought-for value of oil content in water by formula N = a+ ae + am + aT, where N is sought-for value of content of oil in water;are constant coefficients determined during calibration; e, m, T are measured values of electric conductance, damping of SHF radiation and temperature correspondingly. EFFECT: increased measurement accuracy. 1 dwg
