anemometer's Usage Examples:

Robinson published a number of papers in scientific journals, and the Armagh catalogue of stars (Places of 5345 Stars observed from 1828 to 1854 at the Armagh Observatory, Dublin, 1859), but he is best known as the inventor (1846) of the cup-anemometer for registering the velocity of the wind.

Anemometers may be divided into two classes, (1) those that measure the velocity, (2) those that measure the pressure of the wind, but inasmuch as there is a close connexion between the pressure and the velocity, a suitable anemometer of either class will give information about both these quantities.

anemometer cups dawdled on a simpering breeze which was satisfied to box the compass and presently expire.

The other forms of velocity anemometer may be described as belonging to the windmill type.

Lind's anemometer, which consists simply of a U tube containing liquid with one end bent into a horizontal direction to face the wind, is perhaps the original form from which the tube class of instrument has sprung.

Approximately II% should be added to the velocity recorded by a tube anemometer for each 1000 ft.

Velocity anemometers may again be subdivided into two classes, (1) those which do not require a wind vane or weathercock, (2) those which do.

There are 6 models in this range of hand held anemometers.

Probably a sphere would prove most useful for a pressure anemometer, since owing to its symmetrical shape it would not require a weathercock.

Using highly sensitive digital hot-wire anemometers and digital data-logging barometers this was also ruled out for many of the anomalous door events.

In cases where the direction of the air motion is always the same, as in the ventilating shafts of mines and buildings for instance, these anemometers, known, however, as air meters, are employed, and give most satisfactory results.

Unfortunately, when Dr Robinson first designed his anemometer, he stated that no matter what the size:of the cups or the length of the arms, the cups always moved with one-third of the velocity of the wind.

The great advantage of the tube anemometer lies in the fact that the exposed part can be mounted on a high pole, and requires no oiling or attention for years; and the registering part can be placed in any convenient position, no matter how far from the external part.
