Patent ID: 11397146

Abstract:
A viscosity measurement system and method, the system comprising a housing comprising a top cover and a bottom plate, a rod having a first end and a free end, and oscillation generating means, the oscillation generating means being connected through a supporting plate to the first end of the rod, the free end of the rod extending out of the bottom plate through an opening in the bottom plate; wherein the opening bottom in the bottom plate is sealed around the rod by at least one of: compression rings, bellows; a flexible circumferential part of the bottom plate around the opening; Tig welding of the rod to the opening in the bottom plate; and brazing of the rod to the opening in the bottom plate. The method comprises mounting an oscillation generating means connected to a first end of a rod within a housing comprising a top cover and a bottom plate, a free end of the rod extending out of the bottom plate through an opening in the bottom plate; and sealing the opening in the bottom plate around the rod by at least one of: compression rings, bellows; a flexible circumferential part of the bottom plate around the opening; Tig welding of the rod to the opening in the bottom plate; and brazing of the rod to the opening in the bottom plate.
