    Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind ...

  3. Air flow meter - Wikipedia

    en.wikipedia.org/wiki/Air_flow_meter

    An air flow meter is a device similar to an anemometer that measures air flow, i.e. how much air is flowing through a tube. It does not measure the volume of the air passing through the tube, it measures the mass of air flowing through the device per unit time, though Thus air flow meters are simply an application of mass flow meters for the ...

    en.wikipedia.org/wiki/Meteorological_instrumentation

    The 20th century developed new remote sensing tools, such as weather radars, weather satellites and wind profilers, which provide better sampling both regionally and globally. Remote sensing instruments collect data from weather events some distance from the instrument and typically stores the data where the instrument is located and often ...

  5. Airflow - Wikipedia

    en.wikipedia.org/wiki/Airflow

    The speed at which a fluid flows past an object varies with distance from the object's surface. The region surrounding an object where the air speed approaches zero is known as the boundary layer. [3] It is here that surface friction most affects flow; irregularities in surfaces may affect boundary layer thickness, and hence act to disrupt flow ...

    A pair of scales: An instrument for measuring mass in a force field by balancing forces. Balance; Check weigher measures precise weight of items in a conveyor line, rejecting underweight or overweight objects. Inertial balance; Katharometer; Mass spectrometers measure the mass-to-charge ratio, not the mass, of ionised particles. Weighing scale

  7. Sodar - Wikipedia

    en.wikipedia.org/wiki/SODAR

    Sodar systems are in fact nothing more than sonar systems used in the air rather than in water. More specifically, since they operate using the Doppler effect with a multi-beam configuration to determine wind speed, they are the exact in-air equivalent to a subclass of sonar systems known as acoustic Doppler current profilers (ADCP). Other ...

    en.wikipedia.org/wiki/Sound_Velocity_Probe

    Secondly, the surveyor can use a sound velocity probe that can be lowered into the water in the area to be surveyed to measure the actual speed of sound. This has the advantage of being quicker than a bar check and it can be performed when there is boat motion due to swell and sea, although any draft offset of the vessel is not identified using ...

  9. Quartz crystal microbalance - Wikipedia

    en.wikipedia.org/wiki/Quartz_crystal_microbalance

    Quartz is one member of a family of crystals that experience the piezoelectric effect.The piezoelectric effect has found applications in high power sources, sensors, actuators, frequency standards, motors, etc., and the relationship between applied voltage and mechanical deformation is well known; this allows probing an acoustic resonance by electrical means.
