Threaded coupling device with nozzle for GWR measurements in non-metallic tanks

摘要

A coupling device for coupling a threaded feed-through of a process connection to provide a launcher for a non-metallic storage tank. The storage tank includes a tank aperture in its top surface. The coupling device includes a foil nozzle including an inner upper metal foil surface that includes a threaded aperture for securing the feed-through thereto, and a first and second lower metal foil surface on respective sides of the upper metal foil surface. The foil nozzle also includes a first and a second foil level transition region disposed between the respective sides of the inner upper metal foil surface and the first and second lower metal foil surface. The foil nozzle can be configured in a cylindrical, horn, or a corrugated horn shape.
