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 ...

Radiometric or gamma level/density instruments are most often used in applications where other measuring techniques fail due to extreme temperatures or pressures, toxic media, complex geometries of ...

Gas density is frequently estimated indirectly by gas pressure sensors. Because the pressure in a tightly sealed compartment fluctuates greatly with temperature, such systems require temperature ...

Measuring the density of a cell can reveal a great deal about the cell’s state. As cells proliferate, differentiate, or undergo cell death, they may gain or lose water and other molecules, which is ...

Based on the gas displacement method, this article describes a method for determining the optimal gas type and pressure for measuring cement density, providing a reliable method to characterize porous ...
