ABSTRACT:
A process sealed waveguide is formed in a flange mounted on a tank, and is used for transmitting microwave energy from a source of microwave energy to an aperture of an antenna on the interior of the tank. The process sealed waveguide includes a mechanical barrier to prevent escape of fluid under pressure or liquid from the interior of the tank, and also serves to reduce impedance mismatch between the air, vapor, or liquid filled waveguide or antenna apertures. The flange is mated to the microwave source through an electronic housing to flange adapter that interfaces with the flange in a manner to provide a vent in case the mechanical barrier fails so pressure is released, and to provide flame quenching if flames are present. The adapter includes a second waveguide having a process sealed mechanical barrier mounted coaxially with the mechanical barrier in the waveguide in the flange.
