Paul:

Why not place small weights on the floating plate.  Continue to load

until it

does not float and you will know the strength of the flow of air?

Good idea. Sort of a pressure measurement on the face of
the rad. I think even Vance would buy that.
Actually using a water manometer is more accurate and a lot easier.
I just ordered some Hall sensors from Digi Key so I should have
them by Wensday. Hopefully by the end of the week we should have the
remote anemometers working.

Who was it who said "you cannot make a measurement of something without
affecting the outcome" or something like that.  This is a case of that.  By
blocking the flow you cause a locally higher pressure than if the plate
weren't there.  To get accurate results you must disturb the flow as little
as possible.

Werner Isenberg? Amen!
