Abstract
An improved accuracy Coriolis mass flow meter. Signal processing embodiments provide improved accuracy by accounting for the non-linear relationship between phase angle difference of motion sensor signals and mass flow rate. Compensation is made for asymmetric and viscous damping effects, as well.
