Abstract: Drinkers for animals are usually configured as having a single elongate pipe string (24) in which a plurality of drinking valves are screwed in. The drinking valves (20) can operated by the animals themselves to cover their water needs. When no water is being removed by the animals at the drinking valves (20) the water in the pipe string (24) stands still.

The invention proposes the circulation of the water in the animal drinker. To this end, the animal drinker has two parallel pipe strings (23, 24) which form a water circuit ensuring a constant movement of water, namely that water flows continuously through the pipe strings (23, 24) even when no water has been removed at the drinking valves (20) over an extended period of time.

The supervisory controller uses fuzzy logic to make expert decisions, based upon a set of supervisory rules, to control each pumping rate to achieve a desired flow rate and to respond to fault conditions. An adaptive controller corrects temporal variations in the flow rate based upon an adaptive law and a control law.
