Marsh Funnel Viscometer for Cement

Marsh Funnel Viscometer for Cement

The Marsh Funnel Viscometer for Cement is a rugged, easy‑to‑use instrument designed for rapid on‑site measurements of drilling mud and cement slurry viscosity. It’s built to withstand tough field conditions and gives engineers and technicians a reliable assessment of relative fluid viscosity without complex equipment. 

What Is a Marsh Funnel Viscometer?

A Marsh funnel viscometer measures the flow properties of drilling fluids, reporting the time it takes for a known volume (one quart) of fluid to pass through the funnel’s outlet tube. This reading reflects the fluid’s viscosity, expressed in seconds, which helps identify changes in rheological performance that could affect drilling or cementing operations. 

This test is widely used for real‑time field measurement, helping you take quick corrective action if the fluid’s behavior changes unexpectedly.

Key Features

• Durable Construction: Tough plastic body with brass orifice for consistent flow
• Portable Size: Compact design makes it ideal for field operations
• Accurate Readings: Measures time (in seconds) for one quart of fluid to flow out
• Field Tested: Suitable for drilling mud, cement slurries, and other construction fluids
• Easy to Use: Simple procedure requires minimal training
• Commonly Used Standards: Calibrated to flow one quart of water at 70 ± 5 °F (21 ± 3 °C) for consistent baseline readings 
• How It Works

The operator fills the Marsh Funnel Viscometer with the test fluid, covers the outlet tube, then releases it to start the test. The time for the fluid to drain completely is recorded in seconds. These results help you monitor trends or sudden changes in fluid viscosity, which can point to formulation issues or performance changes in real time.

Want to expand your field testing capabilities? Pair this instrument with a Sand Content Kit for Testing Drilling Mud to assess particle levels that affect fluid behavior. 

Applications

• Monitoring viscosity in drilling fluids and cement slurries
• Rapid field checks before or during drilling operations
• Fluid quality control and corrective decision support
• Handy tool for geotechnical and construction testing sites

This viscometer helps you identify flow behavior changes early so you can adjust formulations or operations before issues worsen.
