Density Calculation
Solution Material
Thermo Scientific DensityPRO User Manual C-31

(Dc2u): Density for calibration point 2 – Calibration point 2 is an optional
calibration point. The user enters the density for the second calibration point
in the same units as selected for the first calibration point. The density should
be entered when the second point of the calibration is performed.
– Measured Inputs

I: Radiation Intensity – Counts per second from the detector. The radiation
intensity will be the filtered counts.

Istd: Standardization Counts – The average count rate per second from the
detector during standardization. The detector will calculate the average count
rate during the standardization cycle.

Ical1: Calibration point 1 counts – The average count rate per second from
the detector during calibration of the first point. The detector will calculate
the average count rate during the calibration cycle or during the
standardization cycle when standardized on a full pipe.

Ical2: Calibration point 2 counts – The average count rate per second from
the detector during calibration of the second point. The detector will calculate
the average count rate during the calibration cycle.
– Calculated values

L: Pipe ID (cm) – The inside diameter of the pipe converted from user-
selected units to centimeters.

Dcal1: Calibration point 1 Density – Density for calibration point 1 (Dc1u)
converted to grams per cubic centimeter.

Dcal2: Calibration point 2 Density – Density for calibration point 2 (Dc2u)
converted to grams per cubic centimeter.

D: Density of process material – Calculated density of the process material in
grams per cubic centimeter using
Equation 4 .
Additional
Measurements
In addition to Measurement #1, three additional measurements, Measurements #2 –
#4 are available to display additional parameters measured or calculated by the gauge.
These additional measurements are also capable of displaying the values from the
analog inputs.
