Density is a measurement of fluid weight per unit of volume. This measurement is often referred to as mud weight and is reported as pounds per gallon, pounds per cubic foot, grams per cubic foot, grams per cubic centimeter, kilograms per cubic centimeter, or as Specific Gravity (sg) gms/cm3. The primary function of monitoring density is to control formation pressures and minimize loss of returns.
Balance Density Model 140
Constructed of premium metals for durability, accuracy and ease of use.
The 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 Mud Balance is constructed with an easy-to-read beam which is 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.

Balance Density TruWate Model 141
The TRU-WATE Balance is an instrument for measuring the absolute density of a fluid sample. With the TRU-WATE Balance, the density of a fluid sample, such as cement slurry, can be measured in a fixed volume sample under pressure. By pressurizing the sample cup the entrained air or gas can be decreased to a negligible volume, thus providing a slurry density measurement more closely in agreement with the true density which will be realized under down-hole conditions.
Fann density balances are constructed of premium metals for durability, accuracy and ease of use. A high impact plastic case protects the balance during transport and provides a secure base in its working position.
