The hydrometer sinks deeper in low-density liquids such as kerosene, gasoline, and alcohol, and less deep in high-density liquids such as brine, milk, and acids. It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom.

A salinometer. A salinometer is a device designed to measure the salinity, or dissolved salt content, of a solution.. Since the salinity affects both the electrical conductivity and the specific gravity of a solution, a salinometer often consist of an ec meter or hydrometer and some means of converting those readings to a salinity reading.
For 20 years, it served as the only reservoir serving the city of Columbus' drinking water needs. [3] Griggs Dam is a gravity dam with a 500-foot-long (150 m) curved concrete spillway. Its height is only 35 feet (11 m), but it forms a reservoir almost 6 miles (9.7 km) long with a 1,200,000,000-US-gallon (4.5 × 10 9 L) capacity.
