ABSTRACT:
A viscosimeter for measuring the viscous and elastic properties of a visco-elastic substance continuously in or on a process flow comprises a measuring member which extends into the substance and which is displaced with a reciprocating oscillatory movement, whereby a defined constant shear flow occurs between the measuring member and the said substance. The viscosimeter further includes a connecting linkage connecting the measuring member to a drive, the end portion of the connecting linkage which carries the measuring member and which is enclosed by a bellows member being in the form of a carrier member extending normal to the axis of rotational symmetry of the measuring member. The measuring member is connected to the end of the carrier member in such a way that its geometrical axis coincides with the axis of rotational symmetry. The bellows member only performs pure angular movements which give rise to only very slight measuring errors and which enable it to enjoy a long service life.
