6.Run three batches of fluid, resetting the scale and totalizer between batches. For each batch, record the weights indicated by the scale and the totalizer.

7.Divide Total Weightscale by Total Weighttotalizer. This is the mass-flow meter factor. Record the meter factor.

8.Multiply the meter factor from Step 7 by the first five digits of the current flow calibration factor. This is the first five digits of the new flow calibration factor.

First 5 digits of new FloCal factor

9.Enter the new flow calibration factor into the Flow Cal text box in the Flow panel. The complete flow calibration factor should have eight digits and two decimal points:

•Enter the value from Step 8 as the first five digits and first decimal point.

•For the last three digits and second decimal point, enter the last three digits and second decimal point from the flow calibration factor entered in Step 2.

10.To verify the accuracy of the new flow calibration factor, repeat Step 6. The amount of fluid indicated in the Totalizer Control dialog box should equal the weighed amount of fluid in the batch, within accuracy specifications provided by Micro Motion for the flowmeter.

Characterization involves entering a density calibration factor that accurately represents the sensitivity of the flowmeter to fluid density.

To characterize the flowmeter for density measurement:

1.From the ProLink menu, click on Configuration.

2.In the Configuration window, click on the Density tab. The Density panel, shown in Figure 7-7, is displayed.

3.Enter the 14-character density calibration factor (including the decimal point) into the Density Cal text box. The calibration factor can be found on the flowmeter’s serial number tag, or on the certificate that is shipped with the meter.
