To apply the changes and continue with configuration, click 

. The following popup 

is displayed:

Ensure that your application is in an appropriate state to accept configuration changes, 
then click 

. The new configuration value(s) will be sent to the transmitter, and will take 

effect immediately. The tab display color is reset to gray.

To avoid immediate reconfiguration, click 

. The new setting is retained in 

ProLink II but is not sent to the transmitter.

, 

, or

yellow. You can return to the panel at any point to apply or discard the changes.

5. When you have finished configuration, close the 

 window. You can close the 

window without applying changes.

For many gas applications, standard or normal volume flow rate is used as the quasi mass flow rate. 
Standard or normal volume flow rate is calculated as the mass flow rate divided by the density of the 
gas at a reference condition.

To configure a mass flow special unit that represents standard or normal volume flow rate, you must 
calculate the mass flow conversion factor from the density of the gas at a reference temperature, 
pressure, and composition. ProLink II v1.2 and later offers a Gas Unit Configurator tool to calculate 
this mass flow conversion factor. The tool will automatically update the mass flow conversion factor 
in the 

 tab.

Standard or normal volume is the traditional unit for gas flow. Coriolis meters 
measure mass. Mass divided by standard or normal density yields standard or 
normal volume units.
