FIELD: measuring technique.
SUBSTANCE: method and devices can be used for contact-free measuring mass consumption, density or viscosity of multiple phase fluid flowing inside pipe. Measuring converter has flow-measuring tube provided with channel for letting fluid go, unit for exciting oscillations of tube, detectors receiving oscillations of tube for generation of measuring signals. Flow-measuring tube communicates with pipe through inlet and outlet sections. To achieve axis-symmetrical distribution of density in fluid, motionless turbulence promoter is provided in channel of flow-measuring tube, which turbulence promoter generates rotation motion in flowing medium around axis laying along direction of flowing. According to other variants, turbulence promoter has at least one guide blade. Turbulence promoter has shape of propeller or it can have shape of screw. Precision of measurement improves independently on concentration of non-uniformities and on position of flow-measuring tube.
EFFECT: higher precision of measurement.
