Abstract

Aparato, para controlar el caudal del flujo del vidrio fundido a través de un antecrisol (16) que incluye una canaleta (28) dispuesta en el antecrisol pararestringir el ancho del antecrisol disponible para el flujo del vidrio, de manera tal que exist e una diferencia de niveles del vidrio fundido en el antecrisolcorriente arriba y corriente abajo de la canaleta. Unos sensores (44, 46) miden el nivel del vidrio fundido corriente arriba y corriente abajo de la canaleta,y un controlador (54) reaccio na a los sensores de manera de determinar el caudal del flujo del vidrio fundido a través del antecrisol en forma de una funcionde una diferencia del nivel del vidrio fundido entre los sensores. El caudal del flujo del vidrio fundido a través del ant ecrisol es controlado en forma de unafuncion de la diferencia de niveles del vidrio a través de la canaleta en comparacion con un valor deseado para el caudal del flujo, establecido por eloperario.
