An orifice plate who's required turn down is 10:1 means that the transmitter has to have a turn down ratio of at least 100:1 (Since flow is proportional to dP^1/2). Although some transmitter manufacturers are going to boast that they have transmitters with far more rangeability than this, are...
I've used mechanical equipment numbers to tag instrument devices and I think this is the most effective means of tagging a piece of equipment. That said, some clients prefer suffixes - such as FT-103A and FT-103B and some places prefer things like FT-103-1, FT-103-2, etc.

If anyone...
