Single-Phase
Material
This section describes measuring the density of a single-phase material. Equation 4 is
used to measure density of a single-phase material.
The following definitions are used for density and bulk density.
– Density – Density is defined for substances such as liquids, gases, and solids.
– Bulk Density – Bulk density is a characteristic of substances such as powders,
granules, and other particles like solid substances.
Single-Phase
Density
Calculation
The density for a single-phase material should be calculated using Equation 4 . Initially
the slope correction factor will be 1. When a second calibration point is used, the slope
correction factor should be calculated using
Equation 3 . The user shall have the option
to modify and/or recalculate the slope correction factor at any time.
The parameters below are used to calculate the density of a single-phase material.
– Constants

G: Geometry factor (Default = 0.85) – The geometry factor does not have any
units. It is used to correct for the location of the source relative to the detector
with different source heads and mounting configurations. History has
determined that this value can be a constant.
– User Inputs

Material Type – The user shall be able to select one of the following material
types. The section on Single-Phase Material only applies to the selection of
“Single Phase” for the material type.
 Single Phase
 Slurry
 Emulsion

Solution

Primary Measurement – When the user selects a material type of single phase,
the primary measurement will be density.

Unit for Measurement #1 – The user has the ability to select the units for
Measurement #1. The following unit selections are available.

Grams per cubic centimeter (g/cm3 or g/cm3)

Pounds per US gallon (lb/gal)

Pounds per UK gallon (lb/ImpGal)

Pounds per cubic foot (lb/ft3 or lb/ft3)

Short tons per cubic yard (STon/yd3 or STon/yd3)

Long tons per cubic yard (LTon/yd3 or LTon/yd3)
