Abstract

A flow measurement system (20) is provided according to an embodiment of the invention. The flow measurement system (20) comprises a vibrating flow meter (400) including at least one flow tube (410) and a driver (420) adapted to apply a biasing force on the flow tube (410). The flow measurement system (20) also comprises a meter electronics (450) configured to generate a drive signal to vibrate the flow tube (410) about a first deflected position (1002), wherein the first deflected position (1002) is offset from a flow tube rest position (1001).
