Abstract
A microwave level gauge has a flange adaptor which includes a first end for coupling to a process connecting flange and a second end for coupling to an electronics housing. The adaptor has a section of reduced cross-sectional area along its length between the first and second ends, which defines a thermal transfer restriction that restricts heat transfer from the first end to the second end. A waveguide extends through the adaptor, from the first end to the second end.
