Marsh Funnel Cup

The 1 liter, plastic marsh funnel cup collects the sample from the Marsh Funnel Viscometer. The Marsh Funnel Viscometer is a rugged, easy to operate instrument. It makes rapid, on the spot measurements of drilling mud viscosity. The Funnel reads only general measurements. The frequent reporting of the Marsh Funnel Viscosity will alert the mud engineer to sudden changes. Changes such as; in the mud viscosity that require corrective action. The Marsh Funnel Viscosity provides the ratio of the speed of the mud as it passes through the outlet tube (the Shear Rate) to the amount of the force. The weight of the mud itself causes the mud to flow (the Shear Stress).
