Abstract
Perfeccionamientos en indicadores de nivel de un líquido contenido en un depósito, caracterizados porque comprenden una sonda destinada a ser sumergida en el líquido hasta una profundidad que define el nivel mínimo de líquido en el depósito, una fuente de presión gaseosa que comprende una caja que define una cámara llena de gas que comunica con la sonda, un dispositivo de enclavamiento sensible a las variaciones de presión en el interior de la citada cámara para ocupar al menos dos posiciones distintas, y un sistema de advertencia sensible a la posición ocupada por el dispositivo de enclavamiento, un aumento de presión en la citada cámara resultando en una puesta en marcha de la fuente de presión gaseosa que tiene como consecuencia solicitar el dispositivo de enclavamiento en una posición de enclavamiento para la cual el sistema de advertencia no es puesto en marcha cuando el nivel del líquido en el depósito es superior al nivel mínimo, mientras que una puesta en marcha de la fuente de presión gaseosa cuando el nivel del líquido es inferior o igual al nivel mínimo tiene como única consecuencia el escape del gas por la citada sonda, de forma que el dispositivo de enclavamiento permanece en una posición de reposo para la cual el sistema de advertencia es puesto en marcha.
