Slurry Density
Calculation
When the process material is slurry, the gauge will be able to calculate the density of
the material, and will also be able to provide information on the carrier and solids.
The density for a slurry material shall be calculated using Equation 4 . Initially the slope
correction factor will be 1. If a second calibration point is used, calculate the slope
correction factor using
Equation 3 . The user has 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 slurry 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 has the option of selecting any of the following
material types.

Single Phase
 Slurry
 Emulsion
 Solution
This section only applies to the selection of Slurry for the material type.

Primary Measurement – When the user selects a material type of slurry, the
following options are available for the Primary Measurement.

Density – The density of the slurry is calculated using Equation 4 . The
value will be displayed in the unit’s selected from the list in Units for
Measurement #1 .

Solids content/volume

D = density of the slurry from Equation 4 (g/cc)

Dc = density of the carrier (g/cc)

Ds = density of the solids (g/cc)

Ms = Solid content per volume (g/cc)
