Abstract

A sensor assembly (10) for a flowmeter is provided. A flow tube (20) having a first and second loop (24, 26) are connected by a crossover section (22). The flow tube (20) comprises a thermal expansion bend (300, 302). First and second anchor blocks (30a, 30b) are each attachable to the flow tube (20) proximate the crossover section (22). A tube support (106) is attachable to one of the first and second anchor blocks (30a, 30b). First and second manifolds (90, 92) are attachable to an inlet (50) and outlet (52). A support block (100) is attachable to the first and second anchor blocks (30a, 30b), first and second manifolds (90, 92), flow tube (20), first and second anchor blocks (30a, 30b), and first and second manifolds (90, 92), and allow a predetermined degree of movement due to heating and cooling cycles when not attached to the support block (100).
