You can find both your meter's model (e.g. MSF1 1W20) and the "Feeder Serial #" (usually 05xxxxx or 13xxxxx) under Settings > Hardware > General.
Alternatively, you can check the update status on the meter itself, as follows:
Select Updates History to view a list of the updates that have installed on your system.
You will see the title, size, effective date and installation date of each installed update.
