
Fluid 2 content/volume – Units shall be from the list in Units for
Measurement #1 . The value shall be calculated using Equation 11 with
the terms defined as follows.

Dc1u = density for calibration point 1 (g/cc)

Dc = density of the fluid 1 (g/cc)

Ds = density of the fluid 2 (g/cc)

Ms = Fluid 2 content per volume entered by the user and converted
to grams per cubic centimeter.

Fluid 1 content/volume – Units shall be from the list in Units for
Measurement #1 . The value shall be calculated using Equation 12 with
the terms defined as follows.
 Dc1u = density for calibration point 1 (g/cc)
 Dc = density of the fluid 1 (g/cc)
 Ds = density of the fluid 2 (g/cc)
 Mc = Fluid 1 content per volume (g/cc) entered by the user and
converted to grams per cubic centimeter.

Fluid 2/Fluid 1
Note: Gauge will not be calibrated in these units. This is the
proppant calculation.

Percent by weight fluid 2 (%) – The value shall be calculated using
Equation 13
with the terms defined as follows. Dc1u = density
for calibration point 1 (g/cc)

Dc = density of the fluid 1 (g/cc)

Ds = density of the fluid 2 (g/cc)

Spw = Percent by weight fluid 2 in percent (%) entered by the user.

Percent by weight fluid 1 (%) – The value shall be calculated using
Equation 14 with the terms defined as follows.

Dc1u = density for calibration point 1 (g/cc)

Dc = density of the fluid 1 (g/cc)

Ds = density of the fluid 2 (g/cc)
