    • An electrical interconnect provides a path between cryogenic or cryocooled circuitry and ambient temperatures. As a system, a cryocable 10 is combined with a trough-line contact or transition 20. In the preferred embodiment, the cryocable 10 comprises a conductor 11 disposed adjacent an insulator 12 which is in turn disposed adjacent another conductor 13. The components are sized so as to balance heat load through the cryocable 10 with the insertion loss. In the most preferred embodiment, a coaxial cryocable 10 has a center conductor 11 surrounded by a dielectric 12 (e.g. Teflon.TM.) surrounded by an outer conductor 13 which has a thickness between about 6 and 20 microns. The heat load is preferably less than one Watt, and most preferably less than one tenth of a Watt, with an insertion loss less than one decibel. In another aspect of the invention, a trough-line contact or transition 20 is provided in which the center conductor 11 is partially enveloped by dielectric 12 to form a relatively flat portion 28. The preferred overall geometry of the preferred embodiment of the cable is generally cylindrical, although other geometries are possible (e.g. stripline, microstrip, coplanar or slotline geometries).

    • A field service device (280) for facilitating a processing system replacement in a vibratory flowmeter is provided. The field service device (280) includes a field service device processor (282) configured to interface with one or more vibratory flowmeter processing systems and a storage system (285) configured to store pre-replacement operationally-derived values (252a), post-replacement operationally-derived values (252b), and one or more scaling factors (266). The field service device processor (282) is configured to obtain pre-replacement operationally-derived values (252a), obtain post-replacement operationally-derived values (252b) after an old processing system has been replaced with a replacement processing system, generate the one or more scaling factors (266) as a ratio of one or more pre-replacement operationally-derived values (252a) to one or more post-replacement operationally-derived values (252b), and download the one or more scaling factors (266).
