Marsh Cone (Funnel) Viscometer (AIM 536-1 )

The Marsh Funnel Viscometer (SS with Stand) is a simple device used for routine quick measurements of fluid viscosity. It is an excellent indicator of changes in drilling fluid properties. The Marsh Funnel Viscometer is conical in shape - 152 mm in diameter at the top and 305 mm long with a capacity of 1,500 cm3. A 12- mesh screen covers half of the top and is designed to remove any foreign matter and drilled cuttings from the fluid. The fluid runs through a fixed orifice at the end of the funnel, which is 50mm long by 4.7 mm diameter in size.
