For converting from 1/4'' NPT to G1/4 BSP, here is one source:-
Regarding whether or not the flow rate reading will be off due to a change of inlet/outlet size, I think it depends on the kind of flowmeter.
If it is the rotameter kind (eg King 7520), then it does not matter because the internal float and tapered float tube remain constant.
If it is the Koolance type mentioned above by tippo33, then it does matter.
