Abstract

A pressurised water pipe (2) has an electromagnetic valve (3) near the main watering device (1). A flow sensor (4) is positioned near the valve (3), and also a water tap from which the water flows to a rain and evaporation meter (7). Secondary pipes (21, 22, 23) take the water to secondary devices (81, 82, 83) at the outlet of which are watering devices (91, 92, 93). The rain and evaporation meter has water level detectors producing signals when the water is at an upper and a lower level. The detectors are typically photoresistors connected to potentiometers the signals being translated into logic signals and compared with the flow sensor (4) signals to control the valve (3).
