Title (EN) METHOD AND DEVICE FOR THE CONTROL OF WATER SUPPLY TO PLANTS
(FR) PROCEDE ET DISPOSITIF DE COMMANDE D"ALIMENTATION D"EAU A DES PLANTES
Abstract: front page image
(EN)At least two distribution devices (2, 2") are arranged one behind the other on a pipe fed by a water tank, for the control of water supply to plants. The water flow is adjusted to the needs of all the plants in general by the fact that the water quantity of the last distribution device (2) is continuously compared with the water quantity required for the last plant (4"), and each difference is corrected immediately by varying the total flow. Preferably, the level in one tank (6) communicating with the last plant (4") is controlled by means of a float (7) which controls a flow regulator (5) arranged on the water pipe (1) before the first distribution device (2).
(FR)Au moins deux dispositifs de distribution (2, 2") sont montes l"un derriere l"autre sur une conduite alimentee par une reserve d"eau, pour la commande de l"eau pour des plantes. Le debit d"eau est ajuste a l"ensemble du besoin de toutes les plantes par le fait que la quantite d"eau du dernier dispositif de distribution (2) est continuellement comparee avec la quantite d"eau necessaire de la derniere plante (4"), et chaque difference est corrigee immediatement par modification du debit total. De preference, le niveau dans un reservoir (6) communicant avec la derniere plante (4") est controle au moyen d"un flotteur (7), qui commande un regulateur (5) de debit monte sur la conduite d"eau (1) avant le premier dispositif de distribution (2).
