Question for all: how accurate are fuel flow meters?

I have a very simple one, shows only current fuel flow, and total fuel used
since the last reset. I don't even recall what brand it is.

My experience with it is much more like Peter R.'s than John Smith's. It's
extremely accurate, and consistently predicts how much fuel will be required
to top off the tanks to less than a gallon (to within 0.5 gallon is
typical).
