Agreed. It says all they did was apply the same pressure to both meters. They didn't show what came out the other end. If the valve somehow took advantage of the the meter's design by side loading the impeller or some other way of making it read inefficiently, there'd be a benefit. But not because "air builds up in the water pipelines via internal and external processes." LOL. Of course that'd be illegal, because you don't own the pipe before the meter, and you have no way of shutting it off to install anything. Water meters tend to read a little bit low at extremely low flow rates and extremely high flow rates but the difference is about 1%. They make up for it by reading slightly higher in the middle range. Air is normally dissolved in water and can come out of the water as the pressure drops or the temperature warms up. So the volume can change, but 40% is bullshit. And this thing does nothing to put the air back in. Large heating and chilled water systems have air seperators to keep air bubbles from causing mechanical damage or corrosion. |
