Abstract:
Apparatus for watering plants, with at least one moveable beam, on which are arranged several valves for dispensing water, the degree of opening of which can be adjusted continuously, wherein at least some of the valves each are provided with means (9, 9â€²) for direct or indirect sensing an actual flow value (Qist) and an electronic regulating means that adjusts degree of opening of the valve (6) until the actual flow value (Qist) corresponds to a reference flow value (Qsoll) predetermined by a central control means (7), wherein the apparatus for watering plants is provided with a pressure sensor (9â€²) which detects the meter pressure following the point of restriction formed by a valve member (15) and the apparatus for water plants calculates the flow preferably from a measured water pressure (Pist) and the known diameter (d) of an outlet nozzle (16) connected thereafter.
