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 direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction
In 1450, Leone Battista Alberti developed a swinging-plate anemometer, and is known as the first anemometer. [1] In 1607, Galileo Galilei constructs a thermoscope. In 1643, Evangelista Torricelli invents the mercury barometer. [1] In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge.
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.
Aerographer's mates: observe, collect, record and analyze meteorological and oceanographic data;; make visual and instrument observations of weather and sea conditions, surface and sub-surface;
An anemoscope c1920s built by the American instrument maker Julien P. Friez & Sons is in the collection of Harvard university was designed to be used as part of an automatic wind recorder alongside a wind speed measuring anemometer. [3] Today anemoscopes are used in meteorological stations, and in transport especially boats.
Anemometer, weather vane, anemoscope A windsock (a wind cone or wind sleeve) is a conical textile tube that resembles a giant sock . It can be used as a basic indicator of wind speed and direction , or as decoration.
Military instruments as a class draw on most of the categories of instrument described throughout this article, such as navigation, astronomy, optics, and imaging, and the kinetics of moving objects. Common abstract themes that unite military instruments are seeing into the distance, seeing in the dark, knowing an object's geographic location ...
The issuance of a drawing from the engineering/design activity to the production activity. In other words, the event when a draft becomes a completed, official document. A stamp on the drawing saying "ISSUED" documents that RTP has occurred. RTV: room-temperature vulcanizing; return to vendor: 1. RTV sealants, a way to seal joints. 2.
