Fann No. 201 Marsh Funnel Viscometer is a simple device for indicating viscosity on a routine basis. When used with a measuring cup, the funnel gives an empirical value for the consistency of a fluid. This number (time in seconds) depends on (1) the effective viscosity at the rate of shear prevailing in the orifice, and (2) the rate of gelation.
