Estimating the term…
A digital hydrometer and methods of digitally displaying a specific gravity measured by a hydrometer are provided. The digital hydrometer can comprise a base, a displacement vessel, an inductive distance sensor, an output circuit, and a hydrometer float. The displacement vessel and inductive distance sensor can be mounted in or on the base. The displacement vessel can hold a displacement fluid. The hydrometer float can float in the displacement fluid. The output circuit can be in electrical communication with the inductive distance sensor and comprise a digital display device configured to display a digital value that is commensurate with a change in impedance attributable to the proximity of a metallic object, in the hydrometer float, to the sensor or its inductor. The digital value can be a specific gravity of the displacement fluid.
