CORIOLIS MASS FLOW METER, METHOD OF MEASURING MASS FLOW PASSING IN PIPELINE MEDIUM, APPLICATION OF MASS FLOW METER AND METHOD OF MEASURING MASS FLOW PASSING THROUGH PIPELINE

摘要

FIELD: physics.;SUBSTANCE: flow meter contains a measuring pipe, through which, while working, flows a multiphase medium, an exciter for bending vibrations of the pipe, a sensing device for producing measuring signals (s₁, s₂) of the vibration of the pipe. The control of the exciter of the electric block develops the measuring signals (s₁, s₂) derived from the first intermediate value (X'_m) of the mass flow meter, and the triggering device for the stimulation of current (i_exc). On the basis of current (i_exc) stimulation and/or a part of the current (i_exc) of stimulation produce the second intermediate value (X₂), correspondingly the vibration damping of the measuring pipe, depending on the apparent viscosity and/or the creation of viscosity on the density of the flowing medium. Using the value (X₂) and the preliminarily gotten or during the work value (X_{) of viscosity, corresponding to the viscosity of the flowing medium and/or the reference viscosity, is developed a correcting value (XK) for the intermediate value (X'm). By the values (X'm) and (XK) the electric block derives the exact value (Xm) of the mass flow.;EFFECT: increasing the accuracy of measuring a heterogeneous medium.;19 cl, 9 dwg}
