  2. Density meter - Wikipedia

    en.wikipedia.org/wiki/Density_meter

    The measuring instrument can now calculate the density, as it is dependent on the sound velocity. [3] Another method that is utilized in ultrasonic meters is the envelope energy average method. This method is based on not only the amplitude of the signal but also the shape of the signal. These packets of information are called envelopes.

  3. Gas pycnometer - Wikipedia

    en.wikipedia.org/wiki/Gas_pycnometer

    A gas pycnometer is a laboratory device used for measuring the density—or, more accurately, the volume—of solids, be they regularly shaped, porous or non-porous, monolithic, powdered, granular or in some way comminuted, employing some method of gas displacement and the volume:pressure relationship known as Boyle's law. A gas pycnometer is ...

  4. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    However, each individual method or technique measures different types of density (e.g. bulk density, skeletal density, etc.), and therefore it is necessary to have an understanding of the type of density being measured as well as the type of material in question.

  5. Nuclear densitometry - Wikipedia

    en.wikipedia.org/wiki/Nuclear_densitometry

    In geotechnical engineering, a nuclear densometer or soil density gauge is a field instrument used to determine the density of a compacted material. The device uses the interaction of gamma radiation with matter to measure density, either through direct transmission or the "backscatter" method. The device determines the density of material by ...

  6. Population density - Wikipedia

    en.wikipedia.org/wiki/Population_density

    Living population density by country. Although the arithmetic density is the most common way of measuring population density, several other methods have been developed to provide alternative measures of population density over a specific area. Arithmetic density: The total number of people / area of land

  7. Oscillating U-tube - Wikipedia

    en.wikipedia.org/wiki/Oscillating_U-tube

    U-tube with piezo-electric actuator Digital density measuring principle. The oscillating U-tube is a technique to determine the density of liquids and gases based on an electronic measurement of the frequency of oscillation, from which the density value is calculated. This measuring principle is based on the Mass-Spring Model.

  8. Relative density - Wikipedia

    en.wikipedia.org/wiki/Relative_density

    Relative density is often used by geologists and mineralogists to help determine the mineral content of a rock or other sample. Gemologists use it as an aid in the identification of gemstones. Water is preferred as the reference because measurements are then easy to carry out in the field (see below for examples of measurement methods).

  9. Density logging - Wikipedia

    en.wikipedia.org/wiki/Density_logging

    This method is the most reliable porosity indicator for sandstones and limestones because their density is well known. [1] On the other hand, the density of clay minerals such as mudstone is highly variable, depending on depositional environment, overburden pressure, type of clay mineral and many other factors. It can vary from 2.1 ...
