ABSTRACT:
A gauge tape device detects electronically conductive water level mixtures in various fluids through the use of electricity. The gauge tape device includes a gauge circuit and gauge line, having a weight attached thereto, which is lowered into a containment vessel holding water and other fluids. Once the weight contacts the water, the gauge circuitry activates an alert, which informs the user of the presence of water.
