| titleOfInvention | Acoustic method and device for measuring fluid density or fluid viscosity |
| abstract | Disclose a kind of density value ρ for being used to estimate expression real density ρ m Or for estimating the viscosity number η for the true viscosity η for representing fluid (F) m Method and apparatus (1).Therefore, measurement is located at the first resonant frequency f of the first mechnical oscillator (10) in reference space (RV) R And the second resonant frequency f of the second mechnical oscillator (20) contacted with fluid (F) F .Then these resonant frequencies f is used R And f F Derive estimated value ρ m Or η m .During this derivation, used fluid (F) at least one dependent on fluid temperature (F.T.) or the parameter dependent on Fluid pressure.Additionally or as alternative, first (i.e. benchmark) mechnical oscillator is arranged to be in contact with Reference fluid (R).Thus, reduce and derive estimated value ρ m Or η m In elementary error, and estimated value is become more reliable. |
