Abstract: In one embodiment, an apparatus may meter a level of a liquid. The apparatus includes a float component, wherein the float component includes a sensor and a controller. The sensor senses a parameter usable to determine an inclination of the float component. The controller is operable to receive the sensed parameter, and communicate information based on the sensed parameter to an external controller. When operating to determine a level of a liquid within a container, the apparatus physically contacts the container. Further, at least one of the controller or the external controller is operative to estimate the inclination of the float component based on the sensed parameter, and determine the level of the liquid within the container based on the estimated inclination.

Abstract: A hydrometer embodied as self-contained buoyant structure that reacts to the buoyant force of a fluid by equilibrating at a tilt. The tilt of the structure can then be used to calculate the specific gravity of the fluid. In one embodiment, an accelerometer for measuring the inclination of the buoyant structure, a radio for transmitting the data wirelessly and a battery is contained within the buoyant structure, which allows for a convenient, and efficient automated process for monitoring the specific gravity of a liquid.
