ABSTRACT:
An improved falling float viscosimeter for measurement of over a wide range of viscosities. Use of a plurality of float members, at least one of which contains an aperture, enables the device to measure multiple ranges. Rate of descent of the floats may be easily correlated to the absolute viscosity of the fluid under test. The set of floats may be supplied as part of a complete viscosimeter or separately for extension of range of exisiting instruments.
