A method for fixing an assembly onto a gas vessel configured to contain a pressurized fluid. The assembly including a housing, an electronic acquisition board secured to the housing, and a strain gauge. The method including fixing the strain gauge to the vessel using a second adhesive means, the strain gauge being fixed to the vessel in such a way to allow deformation along with the vessel under the effect of the pressurized gas contained in the vessel. Electrically connecting the strain gauge and the electronic acquisition board using at least one electric cable thereby allowing the housing to be free to move relative to the strain gauge. Fixing the housing to the vessel using a first adhesive means so as to cover the strain gauge and thereby leaving a volume of air between the housing and the strain gauge and/or between the strain gauge and the electronic acquisition board.
