Abstract
A viscometer for measuring liquid viscosities based upon rotational deflections of a suspended bob. The viscometer comprises a deflection indicator, a deflection reader located at a spaced relative position with respect to the indicator, a rotating element which rotates in unison with the bob and includes either the deflection indicator or the deflection reader, and a magnetic bearing assembly which prevents any substantial change in the spaced, relative position of the deflection reader with respect to the deflection indicator.
