ABSTRACT:
A method for determining mass flow rate of media moving through at least one conduit under a flexural vibration comprises analyzing two alternating electrical signals respectively representing the flexural vibration of the conduit at two different sections of the conduit, and determining the mass flow rate as a function of an independent variable generated by a ratio between two groups of various combinations of the two alternating electrical signals, which method also provides a method for determining phase angle difference between two alternating electrical signals without actually measuring the lead time or lag time between the two alternating electrical signals in the time domain.
