A system including a float ball, a pole, a sleeve, an indicator disk, and a dynamo circuit provides information regarding the water level in a tank, and whether fluid is flowing into the tank. The pole slides within the sleeve, through a slab above the tank. A first end of the pole is supported by the float ball, which floats within the tank, while the second end of the pole is located above the slab and supports the indicator disk. A user can detect the water level in the tank based on the height of the indicator disk. A user can also detect whether water is flowing into the tank. The dynamo circuit activates an LED located on the indicator disk when water is flowing into the tank. |
