Marsh Funnel Viscometer Manufacturer,Supplier and Exporter in India
Product Code : TVT-CMTE-10391
The Marsh Funnel Viscometer from Tvet Equipments determines the flow properties of grouts and drilling muds, giving field and laboratory technicians a simple, portable way to check fluid consistency and quality against expected viscosity ranges.
How It Works
A measured volume of drilling mud or grout is poured into the funnel and allowed to discharge through its calibrated outlet tube. Funnel viscosity is expressed as the ratio of the fluid's flow speed through the outlet (shear rate) to the force driving that flow — the fluid's own weight (shear stress) — with the discharge time recorded and compared against reference values to assess mud or grout quality.

Applications
The Marsh Funnel Viscometer is the standard field instrument for drilling mud viscosity testing to API RP 13B-1, widely used on drilling rigs and in geotechnical laboratories to monitor mud quality during operations, and is also applied to efflux-time flow checks on cement-based grouts.

Frequently Asked Questions
Q1. What standard governs Marsh Funnel viscosity testing?
API RP 13B-1 is the primary reference standard for Marsh funnel viscosity testing of drilling fluids.
Q2. What does a longer discharge time indicate?
A longer discharge (funnel viscosity) time generally indicates a thicker, more viscous mud or grout, while a shorter time indicates a thinner, more free-flowing fluid.
