Abstract

Perfeccionamientos en la construcción de sensores térmicos, constituida por un elemento sensible al calor sobre el que influye un medio que fluye pasando, caracterizados porque el elemento sensible al calor es mantenido a una temperatura predeterminada como mínimo aproximadamente constante, siendo la energía adicional necesaria para mantener la temperatura constante una medida para la velocidad del medio que fluye pasando.
