CA 2237270

The invention provides an apparatus and method for fill level monitoring in which the height of contents in a container (10) is monitored. The apparatus comprises an ultrasound receiver (30) and signal processing means (50-56) adapted to receive signals from the receiver, the arrangement being such that the signal processing means (50-56) identifies a first signal (32), in use, which is representative of a wavefront (26) transmitted through the contents of the container (10) independently of the height of the contents in the container (10), and a second signal (34) that is representative of a wavefront (24) that is reflected from the interface (22) between the surface of the contents in the container (10) and the environment above the contents, and in which the signal processing means (50-56) uses the difference in travel time for the two wavefronts (24, 26) to provide a measurement of the level of the contents in the container (10). A plasma generation system comprising a pulsed laser (99) and a target (101) in front of the container (102) is also disclosed, the plasma (103) creating ultrasound in the container (102).

Appareil et procédé de contrôle du niveau de remplissage, permettant de contrôler la hauteur du contenu d'un récipient (10). L'appareil comporte un récepteur d'ultrasons (30) et un dispositif de traitement de signaux (50-56) conçu pour recevoir des signaux du récepteur, la disposition étant telle que le dispositif de traitement de signaux (50-56) identifie un premier signal (32), en cours d'utilisation, représentatif d'un front d'ondes (26) transmis à travers le contenu du récipient (10), indépendamment de la hauteur du contenu du récipient (10), et un deuxième signal (34) représentatif d'un front d'ondes (24) réfléchi par l'interface (22) entre la surface du contenu du récipient (10) et l'environnement au-dessus du contenu; le dispositif de traitement de signaux (50-56) utilise la différence de temps de trajet pour les deux fronts d'ondes (24, 26) pour mesurer le niveau du contenu dans le récipeint (10). Est également décrit un système de production de plasma constitué d'un laser à impulsions et d'une cible (101) placée devant le récipient (102), le plasma (103) produisant des ultrasons dans le récipient.
