Abstract

Perfeccionamientos en ecómetros, caracterizados por comprender un generador de impulsos eléctricos de ondas de corriente alterna para la transmisión; medios para transmitir y recibir ondas de presión, dotados de superficies de transmisión-recepción de ondas de presión, separadas una de otra, en una dirección paralela a la dirección principal de propagación de las ondas de presión, por una distancia apreciablemente distinta de una longitud de onda de frecuencia a la presión de accionamiento; medios de actuación para accionar simultáneamente dichas superficies para la transmisión de ondas de presión por impulsos de dicho generador; y un receptor que tiene un circuito de entrada acoplado a los medios de accionamiento citados, y también al generador mencionado; el acoplamiento a dicho generador es tal que los impulsos del mismo producen un voltaje prácticamente nulo en dicho circuito de entrada.
