D.7 Modifying a density curve

An existing density curve may be modified. The following parameters can be modified without

affecting the enhanced density calculations:

• Curve name

• Concentration unit label and optional text string

• Extrapolation alarm limit

Note: As the value for extrapolation alarm limit is increased, the probability of inaccurate enhanced

density calculations also increases. Micro Motion recommends using the default value for

extrapolation alarm limit.

Do not change any other parameters. In particular, if you change the derived variable, all data are

erased for all existing curves.

D.8 Saving a density curve

Micro Motion recommends that all curves be saved to a file.

To save a curve to a file:

1. In the

ProLink/Configuration window, click on the ED Setup tab.

2. Use the

Curve being configured dropdown list to specify the curve to save, and click Apply.

3. Click the

Save this curve to a file button and specify the file name and location.

4. Repeat these steps for all density curves on your transmitter.
