Abstract
A fill gauge is provided which may be used in connection with a storage container to inform an operator of the relative status of a filling operation. A multiplicity of indicia are progressively displayed to provide an initial warning when the filling operation is nearly completed, and to signal when the filling should be terminated, such as when a desired air-gap has been established. Further indicia may also be provided relating to, for example, an overfilled condition. The fill gauge is reusable and inexpensive, and may be sealed for safe storage. Adjustments for use with fluids of differing density are possible.
