Jed,
I haven't seen the spec sheet m self, but this comment backs up what I
wrote earlier.
Where did you get the idea it would read high? From IH?

Not a problem. Look at the spec sheet, it was used well within its
linear range at these temps. It's a good flow meter with great range,
and the spec sheet even quantitates the error on log scale for if you
use it out of range. It reports 3% less flow than in actuality if you
use it at -half- its lower rating point.
