METRE OF VIBRATION FLOW AND PROCEDURE FOR DETERMINATION OF VISCOSITY OF FLOW MATERIAL Russian patent published in 2011 - IPC G01N11/04 G01F1/84 G01N9/00 

FIELD: machine building.

SUBSTANCE: vibration metre of flow for determination of viscosity of flow material consists of metering unit, of replaceable diaphragm in first pipeline of flow and of electronics of metre configured for reception of first vibration output signal and second vibration output signal, determination of density (ρ), determination of first and second mass flow rate from first and second vibration output signal and for determination of viscosity of flow material from density (ρ), first mass flow rate (m1) and second mass flow rate (m2). The metering unit includes a common drive, the first pipeline of flow and the second pipeline of flow. Also, the common drive is configured to generate simultaneous vibration of the first pipeline of flow and second pipeline of flow to form the first vibration output signal in the first pipeline of flow and simultaneously to form the second vibration output signal in the second pipeline of flow, to form density (ρ) of material of flow, to form the first mass flow rate (m1) for the first pipeline of flow and the second mass flow rate (m2) for the second pipeline of flow.

EFFECT: expanded range of viscosities with facilitation of accurate measurement.
