1. A Coriolis flow meter (100) comprising one or more flow tubes (800, 900), further comprising:
a driver (180) coupled to the one or more flow tubes (800, 900), the driver (180) configured to oscillate the one or more flow tubes (800, 900) in a drive direction;
a pick-off sensor (170L, 170R) coupled to the one or more flow tubes (800,900), configured to measure a movement of the one or more flow tubes (800,900); and
each of the one or more flow tubes (800,900) comprising:
a conduit (852) having an interior surface (854); and
a plurality of solid rod-shaped inserts (856a, 856b, 856c, 856d, 956a, 956b), each being the same, and each respective insert of the plurality of solid rod-shaped inserts (856a, 856b, 856c, 856d, 956a, 956b) being coupled to at least a first position (858) on the interior surface (854) of the conduit (852), wherein the plurality of solid rod-shaped inserts are disposed parallel to the direction of a fluid flow in the flow tube;
wherein the plurality of inserts (856a, 856b, 856c, 856d, 956a, 956b) is configured to generate turbulent flow in the one or more flow tubes, and operable to minimize flow measurement errors generated due to an undermeasurement of fluids in the flow tube under laminar flow.
