Editing Anemometer (section)

====Pitot tube static anemometers====
Modern tube anemometers use the same principle as in the Dines anemometer, but using a different design. The implementation uses a [[pitot tube|pitot-static tube]], which is a pitot tube with two ports, pitot and static, that is normally used in measuring the airspeed of aircraft. The pitot port measures the dynamic pressure of the open mouth of a tube with pointed head facing the wind, and the static port measures the static pressure from small holes along the side on that tube. The pitot tube is connected to a tail so that it always makes the tube's head face the wind. Additionally, the tube is heated to prevent [[rime ice]] formation on the tube.<ref>{{cite web|title=Instrumentation: Pitot Tube Static Anemometer, Part 1|url=http://www.accuweather.com/en/weather-blogs/clarkb/instrumentation/14828|publisher=Mt.

The measurement devices can be [[manometer]]s, [[pressure transducer]]s, or analog [[chart recorder]]s.<ref>{{cite web|title=Instrumentation: Pitot Tube Static Anemometer, Part 2|url=http://www.accuweather.com/en/weather-blogs/clarkb/instrumentation-1/15065|publisher=Mt.
