Pressurized Fluid Density Balance
Pressurized fluid balance to accurately measure the absolute density of a fluid sample is measured by using the Halliburton Tru-Wate pressurized fluid density scale. The operation is similar to the conventional mud balance, with the additional capability of placing the sample in the cup under pressure.
Drilling fluids and foam cements often have a considerable amount of air entrained or trapped within the fluid that may give erroneous results when determining fluid density using conventional equipment. This air volume may be decreased to a negligible quantity by pressurizing the sample cup, which will then give more accurate density
readings of the fluid itself.
The standard scale density may be read directly in units of: lbs/gal
lbs/ft3 specific gravity PSI/1000 ft
