Abstract

Disposicion de medicion de nivel para la medicion de la altura de nivel de un líquido contenido en un tanque empleando un dispositivo emisor/receptorde microondas y un guía-ondas que se extiende hasta dentro del tanque se propone para la medicion precisa y con escala ajustable de la altura del nivelmaterializar al guía-ondas de manera que el mismo presente para una onda con la frecuencia operativa del dispositivo de microondas características depropagacion de onda univocas y constantes. Lo antedicho se logra en particular por medio de un dimensionado adecuado de la seccion transversal de unguía-ondas tubular de manera que su frecuencia operativa se encuentra en el rango monomodo del guía-ondas tubular.
