EXAMPLES FOR CHANGING AND DISPLAYING VARIABLES

This section presents examples involved in changing and displaying variables. In
addressing the steps or procedures involved in accomplishing this, the specific
application example chosen to demonstrate this will be "Application Number
53301510". In this application example, the MODEL 2500 has been configured to
measure the mass and volume flow rate of a process gas containing a mixture of
natural gas liquids and carbon dioxide.
In this case, the MODEL 2500 will calculate liquid propane and liquid butane flow
based on analog input variables for the following:
- Propane temperature (C3TEMP)
- Propane pressure (C3PRESS)
- Butane temperature (C4TEMP)
- Butane pressure (C4PRESS)
The propane input variables C3TEMP is read by ANALOG INPUT channel 1, and
the propane input variable C4TEMP is read by channel 2.
The butane input variable C3PRESS is read by ANALOG INPUT channel 3, and
the butane input variable C4PRESS is read by channel 4.
ANALOG INPUT channels 1 and 2 are the first and second selections in lower
sub-menu ANALOG INPUTS, which is the first lower sub-menu of INPUT
CHANNELS, which is the first sub-menu of the MAIN MENU.
