Morphology

hydrometer = hydro + meter

The meaning is directly compositional: 'hydro' signals water or liquid and 'meter' signals a measuring instrument, so the whole word means a device for measuring liquids' density.

Etymology

Hydrometer comes from Greek parts hydro- 'water' and -meter 'measure', like in hydrogen and thermometer. So a hydrometer is a tool that 'measures' how heavy or dense a liquid is compared with water.
