a device that has both floatability and buoyancy when immersed.
Floats may be of the support type (pontoons of seaplanes and floating bridges, the floats of fishing nets, and hook floats of fishing rods); the hydrometric type, for measurement of flow velocity or variations in level (such as tide gauges); or the actuating type, which operate shutoff valves and other devices depending on the level of a liquid (as in the float chamber of a carburetor and in water-supply systems and the like).
