![]() The faster the cup rotates the higher the frequency and a calibration of frequency against air velocity is derived. They generally have 3 or 4 cups, which as the wind blows, the cup rotates and outputs a frequency. They are a robust style meter that continues to prove itself in the harshest of environments. ![]() Understanding your application, operating conditions and required measurement uncertainty are fundamental to ensuring your anemometer selection is both cost effective and technically conformant.Ĭup Anemometer, is one of the oldest types of anemometer, commonly used in the Meteorological sector for weather measurement of wind speed and direction and are often seen on masts, cranes, weather station, airports, boats, oil rigs and towers. They are now a fundamental day to day measurement across a variety of industries and just as new sectors arrive so do new instrument, methodologies and measurement techniques.Īpart from the minority, we are all subject to cost constraints for our instrumentation purchases and a compromise often necessitates a suboptimal instrument to keep within our budgets. Evolution and technological advances across the globe have seen the expansion of anemometer use into many varying sectors for measurement such as duct velocity in HVAC systems, fume hood performance in laboratories, aerodynamic development for vehicle transportation, exhaust stack flow for environmental emissions, fluid dynamics and so on. ![]() Anemometers are devices that have traditionally been used for measurement of wind speed and direction for meteorological data requirements.
