The marsh funnel is made of break-resistant plastic and has a fixed orifice with a specified diameter. A fixed mesh near the top across half the cone avoids the orifice getting blocked by greater particles. The high-impact plastic measuring cup is designed specifically for use with marsh funnel viscometer and has scales in cubic centimeter and fluid ounces.
The marsh funnel viscosity respectively the funnel flow time is the ratio of the speed of the sample fluid as it passes through the orifice to the amount of force that is causing the fluid to flow. The marsh funnel viscosity is reported as the number of seconds required for 1000 cm³ of sample fluid to flow out of a full marsh funnel.
The MUDTEST marsh funnel complies with the requirements of API RP 13B-1 or the corresponding international standard ISO 10414 for field testing of drilling fluids.
