Set reference temperature values for specific gravity using ProLink III
When Derived Variable is set to any option based on specific gravity, you must set the reference temperature
for water, then verify the density of water at the configured reference temperature. These values affect
specific gravity measurement.
This requirement applies to the following derived variables:
• Specific Gravity
• Concentration (Specific Gravity)
• Mass Concentration (Specific Gravity)
• Volume Concentration (Specific Gravity)
Procedure
1. Choose Device Tools → Configuration → Process Measurement → Concentration Measurement.
The Concentration Measurement window is displayed. It is organized into steps that allow you to
perform several different setup and configuration tasks. For this task, you will not use all the steps.
2. Scroll to Step 2, set Matrix Being Configured to the matrix you want to modify, and select Change
Matrix.
3. Scroll to Step 3, then perform the following actions:
a) Set Reference Temperature for Referred Density to the temperature to which line density will be
corrected for use in the specific gravity calculation.
b) Set Reference Temperature for Water to the water temperature that will be used in the specific
gravity calculation.
c) Set Water Density at Reference Temperature to the density of water at the specified reference
temperature.
The transmitter automatically calculates the density of water at the specified temperature. The
new value will be displayed the next time that transmitter memory is read. You can enter a
different value if you prefer.
4. Select Apply at the bottom of Step 3.
Set up temperature data using ProLink III
The concentration measurement application uses line temperature data in its calculations. You must decide
how to provide this data, then perform the required configuration and setup. Temperature data from the
on-board temperature sensor (RTD) is always available. Optionally, you can set up an external temperature
device and use external temperature data.
The temperature setup that you establish here will be used for all concentration measurement matrices on
this meter.
Important
Line temperature data is used in several different measurements and calculations. It is possible to use the
internal RTD temperature in some areas and an external temperature in others. The transmitter stores the
internal RTD temperature and the external temperature separately. However, the transmitter stores only one
alternate temperature value, which may be either the external temperature or the configured fixed value.
Accordingly, if you choose a fixed temperature for some uses, and an external temperature for others, the
external temperature will overwrite the fixed value.
