ABSTRACT:
A gauge for determining the relative proportions of materials to be added to a container to achieve a desired, predetermined mixture. More precisely, the gauge of the invention measures the level of the mixture remaining in the container and indicates the amount of at least one element of the mixture to be added to the tank before filling the tank with the other element of the mixture to achieve the desired ratio of elements when the tank is full. The gauge is comprised of a cap, gasket, and calibrated stick having a hinge member and retaining feet.
