Abstract

Dispositivo indicador de nivel de fluido para indicar el nivel del fluido en un depósito, que incluye un elemento hueco con una extremidad inferior abierta y una extremidad superior cerrada, una pared móvil situada en el interior del elemento hueco y que responde a los cambios de presión en este último, y un dispositivo sensible a la posición de la pared móvil para generar una señal que depende del nivel de fluido en el depósito, estando dicho dispositivo caracterizado porque el elemento hueco (12) está adaptado para ser sometido totalmente a una presión interna mediante la inversión del elemento en el fluido contenido en el deposito (1) y porque la presión que reina en el elemento hueco (12) es proporcional a la altura (h) del fluido entre los niveles de fluido (A, B) dentro y fuera del elemento hueco.
