Capacitive level gauge assembly for a container for pressurised or liquefied gas, and entity consisting of a valve and a capacitive level gauge

A capacitive level gauge assembly for a pressurized or liquefied gas container comprises a body with a base capable of being fitted in an opening of said container and an electrical circuit arranged in the body; electrode-carrying means are fitted in leakproof manner in said body and connected to said electrical circuit, said electrode-carrying means being configured to support two electrodes fixedly with an annular measurement space therebetween. The electrode-carrying means comprise a metallic support fitted in leakproof manner in the valve body and electrically insulated therefrom, the first electrode being fixed to said metallic support, and the metallic support being connected to the electrical circuit. The metallic support comprises at its free end a coupling means for the first electrode.
