14. 1 Introduction 11 Principle of Operation 1 1 1 Wind Speed and Direction Sensor The MetPak II uses the WindSonic wind speed and direction sensor The WindSonic measures the times taken for an ultrasonic pulse of sound to travel from the North transducer to the South transducer and compares it with the time for a pulse to travel from S to N transducer Likewise times are compared between West and East and E and W transducer If for example a North wind is blowing then the time taken for the pulse to travel from N to S will be faster than from S to N whereas the W to E and E to W times will be the same The wind speed and direction can then be calculated from the differences in the times of flight on each axis This calculation is independent of factors such as temperature NORTH MARKER ARROWS Figure 2 Compass points Figure 2 shows the compass point and polarity of U and V if the wind components along the U and V axis are blowing in the direction of the respective arrows MetPak II User Manual Gill Instruments Ltd Last Change Page 2 02 June 2011 Introduction 1 1 2 Radiation Shield The Multi Plate Radiation Shield protects temperature and relative humidity sensors from error producing solar radiation and precipitation This shield relies on a combination of plate geometry material and natural ventilation to provide effective shielding 1 1 3 Temperature and Relative Humidity Sensor with Dewpoint Output The
