A flow restriction detector for a nozzle assembly of a liquid dispensing machine is capable of detecting a blocked or partially blocked nozzle during the cleaning of the nozzle assembly. During nozzle cleaning, a return plate is attached to the nozzle plate of the nozzle assembly to receive a flow of pressurized fluid from the nozzles. Both the inlet and return fluid lines are provided with pressure sensors, and the return line has a constant back pressure applied to it so that the differential between the inlet and return line pressure sensors is in the range 5-10 psi. The pressure differential is monitored during cleaning and from one cleaning to the next for the purpose of identifying a blocked or partially blocked nozzle. A change of as little as 5% from the pressure differential value established for an unblocked system may indicate a partial blockage of a nozzle.

Un détecteur de restriction du débit pour la buse d'une machine distribuant un liquide est capable de détecter le blocage complet ou partiel d'une buse durant son nettoyage. Durant le nettoyage de la buse, une plaque de retour est fixée à la plaque de la buse pour recevoir un flux de liquide sous pression de la buse. Les canalisations d'arrivée et de retour du liquide sont toutes deux équipées de capteurs de pression, et une contre-pression constante est appliquée à la canalisation de retour, de sorte que le différentiel des pressions détectées par les capteurs des canalisations d'arrivée et de retour est de l'ordre de 5 à 10 lb/po2. Le différentiel de pression est contrôlé durant le nettoyage, et d'un nettoyage au suivant, dans le but de constater s'il y a blocage complet ou partiel de la buse. Un changement d'aussi peu que 5 % par rapport à la valeur établie du différentiel de pression pour un système non bloqué peut indiquer le blocage partiel d'une buse.
