Abstract

Control of fluid flow from a liquid source (1) to a receptacle (2) having at least a measure reservoir (9) with two level detectors (11-12) which deliver characteristic signals, when the fluid reaches the level of a detector, to a controlled device which is interconnected between the source (1), the receptacle (2) and the reservoir (9). The detectors (11-12) send signals to the control device (13) which sequentially controls the controlled device in response to the signals received. The controlled device (7-8) has a three way valve (7) having a first position which connects the reservoir (9) exclusively to the source (1) and a second position connecting exclusively the reservoir (9) with the receptacle (2).
