For the description of ocean currents accurate measurements of the density of sea water are of great importance. For this purpose, measuring instruments are needed which reach a small uncertainty. To ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic centimetre (g/cm³) or kilograms per cubic metre (kg/m³). These balloons are the same ...

A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout is the product of the liquid column height times the density of the liquid. As ...

The variety of industrial applications for different slurries necessitates a reliable method for evaluating the density of these unique mixtures. Accurate and repeatable density measurements can be ...

This release is also available in German. For oceanography – and there in particular for the description of ocean currents – accurate measurements of the density of sea water are of great importance.
