DEVICE FOR MEASUREMENT OF FLOW PARAMETRES Russian patent published in 2010 - IPC G01F1/84 

FIELD: measurement equipment.

SUBSTANCE: application: for measurement of density of fluid medium that flows in pipe. Device for measurement of density of fluid medium flowing along pipe comprises Coriolis metre, having at least one tube installed with the possibility of fluid medium passage through it with formation of frequency signal that characterises own frequency of tube, and/or phase signal, which characterizes difference of phases between two tubes, at the same time device is equipped with facility for measurement of velocity of sound, which is distributed in flow of liquid medium, being installed with the possibility to generate at least one signal selected from group comprising signal that characterises velocity of sound distribution in fluid medium (SV-signal), signal that characterises volume share of has in fluid medium (VGS-signal), and signal of reduced frequency, which characterises reduced frequency of fluid medium, and unit of data processing and determination of corrected measurement result for specific mass flow in response to generation of phase signal, and at least one signal selected from group comprising SV-signal, VGS-signal and signal of reduced frequency and/or detection of corrected result of density measurement in response to acceptance of SV-signal, VGS-signal, signal of reduced frequency and frequency signal.

EFFECT: improved accuracy of density and/or specific mass flow measurement.
