Abstract

The Coriolis flowmeter (100) comprises a driver (180) coupled to a flow tube (800, 900), the driver (180) configured to vibrate the flow tube in a drive direction; pickoff sensors (170L, 170R) coupled to the flow tube, the pickoff sensors configured to measure movement of the flow tube (800, 900); and a flow tube having an inner surface (854) and a plurality of inserts (856a, 856b, 856c, 856d, 956a, 956b), each of the plurality of inserts (856a, 856b, 856c, 856d, 956a, 956b) coupled to at least a first location on the inner surface of the conduit (852).
