System, method, and computer program product for generating a drive signal in a vibrating measuring device

摘要

The present invention relates to a system, method, and computer program product for generating a drive signal for a vibrating measuring device (5). A drive chain (C1, C2, C3, CN) is selected from at least two drive chains (C1, C2, C3, CN). Each drive chain (C1, C2, C3, CN) modifies at least one pick-off signal to generate the drive signal. Each drive chain (C1, C2, C3, CN) generates a different mode of vibration in the at least one conduit (103A). The drive signal generated by the selected drive chain (C1, C2, C3, CN) is provided to a drive (104) of the vibrating measuring device (5).

主权项

1. A system for generating a drive signal in a vibrating measuring device (5), comprising:
at least one conduit (103A) configured to receive a flowing substance; at least one drive (104) that vibrates the at least one conduit (103A); at least one pick-off (105) that measures motion of the at least one conduit (103A); and one or more electronics (20) configured to receive at least one pick-off signal from the at least one pick-off (105), with the one or more electronics (20) including at least two available drive chains (C1, C2, C3, CN), wherein
each drive chain of the at least two available drive chains (C1, C2, C3, CN) modifies a pick-off signal to generate a drive signal including a different frequency and a different mode of vibration in the at least one conduit (103A);with the one or more electronics (20) being configured to select a drive chain from the at least two available drive chains (C1, C2, C3, CN), process the at least one pick-off signal with the selected drive chain to generate a drive signal, and provide the drive signal to the at least one drive (104).
