Mud Balance

The Fann Model 140 Mud Balance provides a simple, practical method for accurate determination of fluid density.

It is one of the most sensitive and accurate field instruments available for determining the density or weight-per-unit-volume (specific gravity) of drilling fluids.

An outstanding advantage of this Mud Balance is that the temperature of the sample does not materially affect the accuracy of readings. A high impact plastic case protects the balance during transport and provides a secure base in its working position.

The Fann Model 140 Mud Balance is constructed with an easy-to-read beam graduated into four scales:

• pounds per gallon
• specific gravity
• pounds per cubic foot
• pounds per square inch per 1,000 feet of depth

The volume of space occupied by entrapped gas or air bubbles in a sample fluid may distort the accuracy of the fluid density measurement. This distortion can be significantly reduced by pressurizing the fluid. The density of a fluid containing entrained air or gas can be determined more accurately by using a pressurized fluid density balance.
