Abstract
Un sistema de desagüe inferior de filtro y un metodo para medir el flujo de agua a traves del sistema de filtro de desagüe inferior. El aparato incluye miembros en forma de panel montados para formar una rejilla perforada sobre la estructura de la base del filtro de un bloque de desagüe inferior. Los paneles son generalmente rectangulares y tienen una superficie superior y una inferior. Se proporcionan multiples aberturas en el miembro de panel. El numero y/o tamano de las aberturas estan dimensionadas para prevenir el egreso del medio filtrante y para obtener un flujo a contracorriente sustancialmente uniforme en el desagüe inferior, reduciendo o eliminando por lo tanto la mala distribucion del agua.
