]]>Product Overview
The TRU-WATE Model 141 Pressurized Mud Balance is a precision instrument designed to deliver highly accurate fluid density measurements by eliminating the effects of entrained air. Unlike traditional mud balances, this model applies pressure to the fluid sample, compressing gas bubbles to provide a true reading of mud or slurry density. Ideal for field and laboratory use, the Model 141 complies with major API standards and is essential for accurate density control in critical drilling and cementing operations.
Key Features TRU-WATE Fluid Density Balance Model 141
-
Pressurized Measurement: Reduces entrained air for more accurate density readings
-
Four Measurement Scales: lb/gal, lb/ft³, specific gravity (g/cm³), psi/1000 ft
-
Rugged & Portable: Durable construction with compact carry case
-
Built-in Bubble Level: Ensures precise beam balancing
-
API Compliant: Meets API RP 13B-1, 13B-2, and 10B-2 standards

]]>The Fann Model 140 Mud Balance provides a fast, reliable way to measure the density (mud weight) of drilling, completion and work-over fluids. Its constant-volume cup and four graduated scales let field crews or laboratory staff read density in multiple units with ±0.1 lb/gal accuracy, ensuring proper hydrostatic pressure control and compliance with API 13B procedures. Because density readings are nearly temperature-independent, the Model 140 is the industry’s go-to mechanical balance for on-site mud checks.
Key Features of Mud Balance Model 140
Wide Density Range: Measures a broad range of fluid densities (typically 6.5–23 ppg or 0.8–2.9 g/cm³), suitable for various drilling fluids.
Direct Reading Scale: Calibrated scale provides immediate and accurate readings in multiple units (lb/gal, g/cm³, lb/ft³, kg/m³).
High Accuracy: Precision knife-edge balance with bubble level ensures readings are consistent and reliable.
Durable Construction: Made from corrosion-resistant materials (e.g., anodized aluminum or stainless steel), ideal for harsh field conditions.
Portable and Field-Ready : Compact and lightweight, often supplied with a protective carrying case for easy transport.
Simple Operation: No power or electronics required; mechanical operation allows use in remote locations.
Multi-Unit Graduations: Allows convenient measurement for various industry standards and international use.
| Feature | Benefit |
|---|---|
| Four integrated scales (lb/gal, specific gravity, lb/ft³, lb/in² per 1000 ft) | Immediate conversion between common oil-field units |
| Wide measuring range – 7 to 24 lb/gal (0.84 – 2.88 SG) | Covers light completion fluids up to heavyweight drilling muds |
| Temperature-stable design | Sample temperature has negligible effect on accuracy |
| Built-in bubble level & knife-edge fulcrum | Quick leveling and precise balancing on any rig floor |
| Rider weight with fine graduations | Readability to 0.1 lb/gal, 0.5 lb/ft³, 0.01 SG |
| Durable anodized beam & stainless cup | Resists corrosion from oil-based or salt-saturated fluids |
| Portable hard case with integral stand | Protects the balance and doubles as the base support |
Applications
Oil & Gas Drilling: Monitors mud weight to control formation pressure and prevent blowouts.
Geotechnical and Civil Engineering: Measures slurry or drilling fluid densities in soil investigations and borehole drilling.
Horizontal Directional Drilling (HDD): Maintains proper mud density for borehole support during underground utility installations.
Mining and Mineral Exploration: Used in exploration boreholes to manage drilling fluid consistency.
Environmental Drilling and Monitoring Wells: Ensures proper mud density to avoid borehole collapse and contamination.
Laboratory Testing of Fluids: Verifies properties of drilling or treatment fluids in controlled lab settings.
