Emulsion
Material
An emulsion material is one fluid suspended in another fluid. Emulsions will be treated
similarly to slurries by the gauge. Fluid 1 will be treated as the carrier and fluid 2 will
be treated as the solid.
Emulsion Density
Calculation
When the process material is an emulsion the gauge will be able to calculate the density
of the material, as well as be able to provide information on the fluid 1 and fluid 2.
Calculate the density for an emulsion material using Equation 4 . Initially, the slope
correction factor will be 1. When a second calibration point is used, calculate the slope
correction factor using
Equation 3 . The user has the option to modify or recalculate
the slope correction factor at any time.
The parameters below are used to calculate the density of an emulsion 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 Emulsion for the material type.

Primary Measurement – When the user selects emulsion as the material type,
the following options are available for the Primary Measurement.

Density – The density of the emulsion is calculated using Equation 4 .
The value will be displayed in the unit’s selected from the list in Units for
Measurement #1 . Some of the terms of Equation 4 are redefined for an
emulsion.

Dc: Density of the fluid 1

µc: Attenuation Coefficient of the fluid 1

Ds: Density of the fluid 2

µs: Attenuation Coefficient of the fluid 2
