Abstract
A flow device is provided. The flow device includes at least one conduit () and a pick-off () providing a pick-off signal () for measuring motion of the at least one conduit (). The flow device also includes a drive () that receives a first signal () for vibrating the at least one conduit () at a resonance frequency and that receives a second signal () for vibrating the at least one conduit at a frequency that is different than the resonance frequency. One or more electronics () is provided. The one or more electronics () generates the first and second signals (,), receives the pick-off signal () from the pick-off (), and measures changes in a time shift between the second signal () frequency applied by the drive () and the second signal () frequency detected by the pick-off ().
