Rotational viscometer

An equipment for measuring viscosity in any type of fluids, both in turbulent, and laminar flow, and especially in heterogeneous suspensions with the presence of large particles or fibres, mainly made up of a rotor formed by a shaft (1) with plates or baffles (2) of suitable dimensions, assembled on bearings (3) and driven by a variable speed motor (6), to which a torque measuring system (7) is associated in shaft (1) by means of an arm (8) joined to the rotating element, shaft (1) rotating inside a container or beaker (4) provided with uniformly distributed plates (5), assembled on another bearing (11) to allow its free rotation according to the torque forces transmitted by the fluid, with a torque measuring system (9) in beaker (4), related by means of an arm (10) joined to the same.
