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

A guided wave radar (GWR) system, comprising:

• a GWR transceiver comprising an electronic block including a processor coupled to a transceiver in series connection with a transmission line connector and a launcher including a feed-through which provides a threaded process connection to a coupling device, said coupling device including:
• a foil nozzle for sealing a tank aperture in a top surface of a non-metallic storage tank, said nozzle including:
• an inner upper metal foil surface including a threaded foil aperture for securing said feed-through thereto, and
• a first and a second lower metal foil surface on respective sides of said inner upper metal foil surface, and
• a first and a second foil level transition region disposed between said respective sides of said inner upper metal foil surface and said first and second lower metal foil surface.
