Patent number: 6769163Abstract: A Coriolis flowmeter having a single flow tube surrounded by connecting rings and a balance bar whose ends are connected by the connecting rings to the flow tube. The balance bar has a thermal coefficient of expansion greater than that of the connecting rings and the flow tube. The outer circumferential surface of each connecting ring is tapered toward the axial center of the flow tube. The inner circumferential surface of the balance bar has a taper matching that of the connecting ring. The connecting ring can only be partially inserted into the space between the flow tube and the balance bar when the assembly is at room temperature. Braze material is then applied to the visible ends of the surface common to the balance bar and the connecting rings as well as to the ends of the surface common to the connecting rings and the flow tube. The structure is heated to brazing temperature to braze these common surfaces.Type: GrantFiled: November 27, 2002Date of Patent: August 3, 2004Assignee: Micro Motion, Inc.Inventor: Craig Brainerd Van Cleve

Patent number: 6718615Abstract: A method of forming a flowmeter having a case enclosing a single straight tube surrounded by a balance bar. The balance bar ends are coupled by means of a brace bar to the flow tube as well as by case connect links to the inner wall of the case. The flow tube projects beyond the case end and is sealably coupled to a cone connect element in the case end. A void is defined by the space between the flow tube outer surface and the inner surface of the cone connect element and the end flanges. The case connect links contain out of plane bends to accommodate a change in the effective diameter of the case and the balance bar with respect to each other due to changing thermal conditions.Type: GrantFiled: September 5, 2001Date of Patent: April 13, 2004Assignee: Micro Motion, Inc.Inventors: Craig Brainerd Van Cleve, Gregory Treat Lanham, Curtis John Ollila, Ernest Dale Lister
