I take the manufacturer's and ERV's word for the flow over Murray's.

Says who? I doubt it. In any case, the flow meter was wrong. Whether
it was under surveillance or not, it was wrong. I doubt the pressure
gauges showed 0.0, but if they did, they were wrong too.
Read what the manufacturer actually says, not what Jed writes. It
is good for the actual flow rate.
No, the flow rate was below the minimum according to the
manufacturer's face plate, and the pipe was only half full. The
manufacturer's manual says a half-full pipe will give the wrong
answer. It warns against it. Peter Gluck says that condition cannot
occur, but this manual and other flow meter manuals I have seen warn
against it, so I suppose it can occur. Why would they warn against a
condition that cannot happen?
