Abstract

A method for reducing flowmeter braze joint stress is provided. The method comprises the step of bending a flow tube (20) to create at least one thermal expansion bend (300, 302) thereon. The method comprises the step of aligning a flow tube (20) with at least one anchor block (30a, 30b). Additionally, the flow tube (20) is brazed to the at least one anchor block (30a, 30b) in another step, after which the flow tube (20) and the at least one anchor block (30a, 30b) are allowed to cool and contract a predetermined degree after brazing. The method additionally comprises the step of attaching the at least one anchor block (30a, 30b) to a support block (100) after the flow tube (20) has been attached to the at least one anchor block (30a, 30b) and attaching a manifold (90, 92) to each end of the flow tube (20).
