Wind speed is typically measured using an anemometer, with common types including the cup anemometer, vane anemometer, hot-wire anemometer, ultrasonic anemometer, and Pitot tube. These instruments work by detecting the movement of air, either through mechanical rotation, changes in electrical resistance, sound wave travel times, or pressure differences. Wind speed is usually expressed in meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), or knots. #windspeed #wind #scienc

The FieldPiece SDMN6 dual-port manometer measures both positive and negative pressure on vacuum control lines. The device will take differential pressure readings and display the difference between P1 and P2 at all times in the lower right corner of the LCD. Watch Bryan explain the different measurements on a manometer and how to prevent common mistakes in this video.
