1. A viscosity measurement system, comprising a measuring element and a housing, the measuring element comprising a base and a counterweight, forced oscillation generating means, a tube, and a rod; the base, the counterweight and the forced oscillation means being sealed in the housing; the tube extending out of the housing through an opening in a bottom wall of the housing; the forced oscillation generating means being connected to an electric board secured to a top wall of the housing opposite the bottom wall for excitation of the rod; the rod extending within the tube and immerging of the housing of the tube out for immersion, at least in part, in a fluid to be measured;
wherein the counterweight is distant from a top wall and from lateral walls of the housing, and the base is supported by the bottom wall of the housing in such a way to simultaneously provide a rigid attachment on an outer circumference of the bottom wall and on a circumference of the opening in the bottom wall, and a flexible dampening attachment on a remaining of an interface between a bottom surface of the base of the measuring element and an upper surface of the bottom wall of the housing.
