FIELD: measurement technology. SUBSTANCE: proposed method is based on use of characteristics of electromagnetic wave probing tested liquid and of electric wave passed through tested liquid. Probing is conducted perpendicular to flow of tested liquid. Reception of electromagnetic wave passed through tested liquid is executed on side opposite to side of probing. Two orthogonal polarized components are extracted from electromagnetic wave passed through tested liquid, continuity of tested flow is found by difference of phases between them. EFFECT: improved reliability of method. 1 dwg
