Abstract: Vibratory meters (5), and methods for their use measuring a fluid are provided. Each vibratory meter includes a multichannel flow tube (300) comprising two or more fluid channels (302), a pickoff (170), a driver (180), and meter electronics (20) configured to apply a drive signal to the driver at a drive frequency ω, and measure a deflection of the multichannel flow tube with the pickoff. At least one fluid channel has an effective diameter that is related to the length of the flow tube.

In examples, at least one fluid channel has an effective diameter that is related to kinematic viscosity, inverse Stokes number, and drive frequency. In further examples, the driver may apply a drive signal to the driver having a drive frequency proportional to the kinematic viscosity, inverse Stokes number, and effective diameter.

Abstract: A method for forming a pressure fit hermetic seal between a second component (104) and an interior member (108) is disclosed. The method comprises steps of coupling the second component (104) to a first component (102) by applying heat to one or more of the first component (102) and the second component (104) and allowing the first component (102) and the second component (104) to cool, wherein the applying heat step and allowing to cool step form the hermetic seal by causing compression of a hermetic element (106) against the second component (104) and by causing compression of the hermetic element (106) against the interior member (108).

Abstract: A multichannel flow tube (300) for a vibratory meter (5), and a method of manufacturing the multichannel flow tube are provided. The multichannel flow tube comprises a tube perimeter wall (304), a first channel division (302b), and a first support structure (308a). The first channel division is enclosed within and coupled to the tube perimeter wall, forming a first channel (306b) and a second channel (306c). The first support structure is coupled to the tube perimeter wall and the first channel division.
