Claim 2:
3. The level gauge according to claim 1, wherein the attachment collar includes:
an annular sealing surface,
an annular abutment surface located radially outside said sealing surface and configured to abut an outer periphery of the tank nozzle, and
a ridge located radially outside said abutment surface;
such that, when the gauging instrument is mounted on a tri-clamp flange of a tank nozzle, said ridge surrounds the outer periphery of the tri-clamp flange to thereby ensure radial alignment, said annular abutment surface abuts the periphery of the tank nozzle to ensure a precisely defined axial relation, and the sealing gasket is sandwiched between said sealing surface and the tri-clamp flange.
