Title (EN) FINE PARTICLE FLOWMETER
(FR) DEBITMETRE POUR PARTICULES FINES
Abstract:
(EN) A flow meter (100) for determining the flow rate or mass of a moving stream of fine particles (P) comprises a guide (102) for guiding the material along a predetermined path having an entry end (106) and an exit end (108). A transducer (200) is operatively associated with one end of the guide and includes a mechanical column connected between a load cell and the exit end of the guide. The load cell produces an electrical output signal proportional to the flowe rate of the material on the guide. A vibrator for vibrating the guide is provided and serves to keep the flow stream moving and wherein the plane of vibration is perpendicular to the plane of measurement, thus eliminating measurement error due to the vibrational forces.
(FR) Un débitmètre pour déterminer le débit ou la masse d'un flux mobile de particules fines comprend un système de guidage pour guider la matière à mesurer le long d'une voie prédéterminée comportant une extrémité d'entrée et une extrémité de sortie. Un transducteur est raccordé de manière fonctionnelle à une extrémité du système de guidage; il comprend une colonne mécanique raccordée entre une cellule de mesure et l'extrémité de sortie du système de guidage. La cellule de mesure émet un signal électrique de sortie proportionnel au débit de la matière dans le système de guidage. Un système pour faire vibrer le système de guidage sert à maintenir le mouvement du flux; comme le plan des vibrations est perpendiculaire au plan de mesure, cela élimine les erreurs de mesure dues aux forces de vibration.
