Jed,
As you should know by now, as it has been repeated several times, the
detailed manufacturer's literature shows that the flow meter works well
at the actual flow rate. Presumably the faceplate shows the boundaries
for which the normal accuracy warranty applies. As the flowmeter was
calibrated by the manufacturer there should be no problem.
There is no evidence the pipe was only half full except for Murray's
claim of "stains." Apparently he didn't see the plant in operation. It
has been explained the drain only half emptied the pipe. What is
required is a detailed pipe drawing when an engineer can tell if that
was a potential problem. As Murray has failed to back up his claim with
such a drawing or even a description and apparently lacks experience in
these matters, I rate the ERV's opinion higher.
There i no known conflict between the ERV and manufacturer.

I take the manufacturer's and ERV's word for the flow over Murray's.
The manufacturer's face plate says this flow meter's minimum flow is
higher than what Rossi recorded! The manufacturer's manual says you
should not run this in a half-full pipe, which is what Rossi did. If
you take the manufacturer's word, then you cannot take the ERV's word.
They are in conflict.
Which do you believe? They cannot both be right.
