Measurement of the depths in the sea based on hydrostatic pressure.

Measuring the forces exerted by fluids in motion.

1. An instrument for determining the specific gravity of a liquid, commonly consisting of a graduated tube weighted to float upright in the liquid whose specific gravity is being measured.
2. An instrument used to determine specific gravity, especially a sealed, graduated tube, weighted at one end, that sinks in a fluid to a depth used as a measure of the fluid's specific gravity.

1. Made by means of a hydrometer; as, "hydrometric observations".
2. A reference to a hydrometer, or to the determination of the specific gravity of fluids.
3. Of or pertaining to measurement of the velocity, discharge, etc., of running water.

An instrument that measures and records the rate of water discharge from a pipe or an orifice.

1. The science and technology of measuring specific gravities, particularly of liquids.
2. Determination of the specific gravity of a fluid by means of a hydrometer.
