drilling fluid viscosity Funnel viscometer rotational viscometer

Funnel viscometer measurement principle is a certain amount of drilling fluid under gravity from a funnel fixed in the time required to flow freely, said drilling fluid viscosity. Usually with “S” to represent. It roughly reflects the whole drilling fluid rheological parameters and other physical characteristics of a comprehensive, best characterized by low shear rate, drilling fluid properties.
