ABSTRACT:
A gauge for determining the headspace in a liquid-filled container. The gauge is composed of a flat bar of transparent material having a beveled upper horizontal edge, and a series of probes of progressively increasing length extend downwardly from the lower edge of the bar. The gauge is placed on the upper edge of a container with the probes extending downwardly into the interior of the container. Darkened spots will appear on the beveled surface above the probes that are engaged with the liquid in the container, thereby providing a precise indication of the headspace or liquid level in the container.
