Model 140 Mud Balance — Four-Scale Drilling-Fluid Density Balance

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.
Drilling & Work-over Rigs – Daily mud-weight checks to control formation pressures
Mud Plants & Service Labs – Incoming product QA and blend verification
Cementing & Spacer Design – Quick density confirmation before pumping jobs
Geothermal & Mining Operations – Fluid density monitoring in harsh field conditions
Academic & Training Centers – Hands-on tool for teaching fluid-property measurem

Included Accessories

  • Constant-volume balance cup with vented lid
  • Four-scale balance arm with rider weight
  • Knife-edge and bubble level assembly
  • Base stand or protective plastic carrying case (with integral fulcrum)
  • Lead-shot counterweight set (installed)
  • Instruction manual & calibration guidelines

 Pro Tips

  1. Calibrate with fresh water (8.34 lb/gal at 70 °F) each tour to verify accuracy.
  2. De-aerate foamy samples with a pressurized mud deaerator for best results.
  3. Keep the cup and lid clean and dry between tests to avoid scale buildup that can shift the rider setting.
