Abstract

Un système de détection automatique est prévu pour détecter des perturbations dans l'écoulement de liquide d'un récipient ou de contenants de liquide à un appareil de distribution. Deux modes de réalisation du système sont décrits. Dans le premier mode de réalisation, un seul récipient de liquide est utilisé. Dans le second mode de réalisation, deux contenants de liquide sont utilisés. Dans les deux modes de réalisation, un capteur optique est utilisé pour détecter une interruption de l'écoulement de liquide depuis les récipients de liquide vers l'appareil de distribution.
