<-There were only two flowmeters on the water from the pumps. The two pumps <without were not running.

If you look at the videos by NyTeknik and S. Allan, you can see two in-line flow-through volume meters: one at outlet of the water pump at the short end of the container, and one at the rightmost water pump at the side of the same. The two pumps at the left were, according to Mats Lewan, not running, even though the valves connecting their outputs to the container are still open. The water level in the reservoirs were, according to reports, kept constant by automatic valves connected to the water mains. /A.
