A hemispherical-cup anemometer of the type invented in 1846 by John Thomas Romney Robinson. In meteorology, an anemometer (from Ancient Greek άνεμος (ánemos) 'wind' and μέτρον (métron) 'measure') is a device that measures wind speed and direction. It is a common instrument used in weather stations.
Anemometer; Ultrasonic flow meter; Mass flow meter (Coriolis force). Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.
A measuring cup, a common instrument used to measure volume. Buoyant weight (solids) Eudiometer, pneumatic trough (gases) Flow measurement devices (liquids) Graduated cylinder (liquids) Measuring cup (grained solids, liquids) Overflow trough (solids) Pipette (liquids) If the mass density of a solid is known, weighing allows to calculate the volume.
Wind speed is measured by anemometers, most commonly using rotating cups or propellers. When a high measurement frequency is needed (such as in research applications), wind can be measured by the propagation speed of ultrasound signals or by the effect of ventilation on the resistance of a heated wire.

An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [ 1 ] In meteorology , wind speed , or wind flow speed , is a fundamental atmospheric quantity caused by air moving from high to low pressure , usually due to changes ...
Asthma is one of the most common lung diseases in the world, affecting some 262 million people worldwide and causing more than 450,000 deaths annually, per the World Health Organization.While ...
Anemometer: An instrument to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.
Fold in 1 cup cheddar and 3 tablespoons blue cheese. Fold in chicken; season with remaining 1/4 teaspoon salt, if needed. Spread chicken mixture in a 11" x 7" ceramic baking dish.
