Marsh Funnel Viscometer

Descriptions
The Marsh Funnel Viscometer is a rugged, easy to operate instrument that is used for
making rapid, on the spot measurements of drilling mud viscosity. The Marsh Funnel
readings are only general measurements, but the frequent reporting of the Marsh
Funnel Viscosity will alert the mud engineer to sudden changes in the mud viscosity
that could require corrective action.
The Marsh Funnel Viscosity is the ratio of the speed of the mud as it passes through
the outlet tube. (The shear rate) to the amount of force - the weight of the mud itself
- that is causing the mud to flow (the shear stress). Marsh Funnel Viscosity is
reported as the number of seconds required for one quart of mud to flow out of a full
Marsh Funnel.
