Marsh Funnel Viscometer and Cup, 1 Liter Measuring Guide

Marsh Funnel Viscometer and Cup – 1 Liter Measuring Guide

The Marsh Funnel Viscometer with 1 Liter Measuring Cup is a rugged, easy-to-use instrument designed for quick on-site measurements of drilling mud and cement slurry viscosity. Its durable construction ensures reliable readings even under field conditions, making it an essential tool for engineers, mud specialists, and drilling technicians. 

Overview

The Marsh Funnel Viscometer provides general viscosity measurements that alert engineers to sudden changes in fluid properties. The instrument calculates the ratio of shear rate to shear stress—the speed of fluid flow through the outlet tube versus the force of the fluid itself—to determine viscosity. Standard readings report the time in seconds for one quart (946 mL) of fluid to flow through the funnel.

For field and lab operations, pairing this viscometer with a 1 Liter Plastic Marsh Funnel Measuring Cup ensures accurate fluid collection and consistent results.

Key Features & Benefits

• Tough and Durable: Built for rigorous drilling site conditions
• Quick Measurements: Provides fast, rough readings to allow immediate corrective action
• Critical Monitoring Tool: Optimizes drilling mud and cement slurry performance
• Measures Flow Properties: Calculates shear stress and shear rate for fluid behavior analysis
• Convenient Design: Double spout and molded scales for easy reading
• Wide Compatibility: Works with OFITE Marsh Funnel Viscometers and other drilling fluid testing equipment

How It Works

1. Fill the Marsh Funnel with the test fluid
2. Use the built-in 12-mesh screen to filter out debris
3. Cover the outlet tube with your finger and release to start the test
4. Record the time taken for one quart of fluid to flow
5. Compare readings with baseline measurements to detect changes in viscosity

This simple yet effective process allows engineers to quickly identify issues and take corrective action for smooth and efficient drilling operations.
