I suppose that Rossi may not be telling the truth as you have concluded, but I am attempting to give him the benefit of the doubt. You and I both would prefer to see a gauge that is more precise than 1000 kg/day but that does appear to be be in line with an approximately 3% error that is specified. I get 1000/36000 * 100=2.777%. And, if he actually did look at the total average flow rate throughout the test, it might indeed read 36000 because of the meter increments. This certainly seems convenient, but would be possible.
The other issue concerning the question as to whether or not the water completely filled the gauge may depend upon whether or not the pump was located ahead of the meter. A similar problem often occurs in hydraulics when a filter is placed ahead of the pump in the suction line. In that case it is possible to damage the pump by cavitation if the fluid flow is restricted by pressure loss within the filter. So, perhaps in this case Rossi has placed a high pressure loss piping component within the system. If the water flow gauge is placed beyond the restriction, then that portion of the piping might be starved of water even if located at the lowest point within the system. The output port of the pump would be full of water while the input is starved. Could this represent what is being observed? Whether intended or not the gauge might loose its accuracy as you are suggesting.

I just read his article and it clearly says that this is the average rate of flow for the test period. How do you draw the conclusion from his article that the rate is exactly the same each and every day? He lied. I expect he wanted to give the impression it was an average, because I think many people realize that saying it is exactly 36,000 per day is absurd. But his data shows exactly that much for every day. As you see from the instrument it can only show an even multiple of thousands, which is also absurd, for this volume. Imagine if he had told Lewan "we record exactly exactly 36,000 kg per day." People would be suspicious! People here are suspicious. His supporters think I made that up, or I am lying. I also read that the flow meter was placed within the lowest point of the system. I recall he did say that. He lied again! Seriously. - Jed
