Emerson Micro Motion Configuration And Use Manual

Restriction
If Derived Variable is not set to Specific Gravity, do not change any of these values. These are set by the
active concentration matrix.
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 click
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 want to.
4. Click the Apply button at the bottom of Step 3.

Set up temperature data for concentration measurement
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.
You can set up an external temperature device and use external temperature data if you
want to.
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 an external
temperature or the configured fixed value. Accordingly, if you set up polling for temperature in one
