Abstract
New level indicator for liquids that is essentially characterized in being constituted by a closed box with a central slot arranged along one face thereof; a sheet of dark color that slides inwardly in the same direction as the groove, and in whose descent it discovers the interior background of the box, painted in light color, except for the last stretch that is red in color; a graduated plate that is fixed on the corresponding face of the groove, whose plate is transparent throughout the area corresponding to this groove, in order to leave visible the aforementioned sheet and background, while the sides of said transparent area carry arranged a numerical scale of capacities, and printed in usual units of the liquid to be measured; and a closed lampholder that together with the box and plate assembly, emits, through a hole or slit, a light that illuminates the graduated scale.
