1. Align the transmitter in such a way that the arrow at the bottom of the transmitter points to north see North Alignment 4 Tighten the fixing screw to fix the adapter firmly to the mast North Alignment To help the alignment there is an arrow and text North on the bottom of the transmitter The transmitter should be aligned in such a way that this arrow points to the north Wind direction can be referred either the true north which uses the earth s geographic meridians or to magnetic north which is read with a magnetic compass The magnetic declination is the difference in degrees between the true north and magnetic north Compass Alignment Orion 420 Weather Station 23 1 Ifthe sensor transmitter is already mounted loosen the fixing screw on the mounting adapter 2 Use a compass to determine that the transducer heads are exactly in line with the compass and that the arrow on the bottom of the transmitter points to north 3 Tighten the fixing screw on the mounting adapter when done Once the sensor transmitter is aligned to north the transmitter can be removed from the mounting adapter without loosing the north orientation Installing the Mast The sensor transmitter measures wind speeds of up to 115 mph 60 m s However unless the mast is properly mounted to withstand such high winds this capability is useless Please read these instructions carefully to insure a safe and reliable installation Mountin2. Using V values of two array paths is enough to compute wind speed and wind direction A signal processing technique is used so that wind speed and wind direction are calculated from the two array paths of best quality The wind speed is represented as a scalar speed in selected units m s kt mph km h The wind direction is expressed in degrees The wind direction reported indicates the direction that the wind comes from North is represented as 0 east as 90 south as 180 and west as 270 The wind direction is not calculated when the wind speed drops below 0 05 m s In this case the last calculated direction output remains until the wind speed increases again to the level of 0 05 m s The average values of wind speed and direction are calculated as a scalar average of all samples over the selected averaging time 1 900 s The sample count is based on a 4 Hz sampling rate The minimum and maximum values of wind speed and direction represent the corresponding extremes during the averaging time Barometric Pressure Temperature and Relative Humidity PTU Module Barometric pressure temperature and humidity measurements are combined in an advanced sensor module PTU utilizing a capacitive measurement method for each parameter The PTU module contains separate sensors for pressure temperature and humidity measurement The measurement principle of the pressure temperature and humidity sensors is based on an advanced

22. he sensor utilizes ultrasound to determine horizontal wind readings The array of three equally spaced ultrasonic transducers on a horizontal plane is an ideal design that ensures accurate wind measurement from all directions without blind angles or corrupted readings The wind sensor has no moving parts which makes it virtually maintenance free Wind speed and wind directions are determined by measuring the time it takes the ultrasound to travel from each transducer to the other two The wind sensor measures the transit time in both directions along the three paths established by the array of transducers This transit time depends on the wind speed along the ultrasonic path For zero wind speed both the forward and reverse transit times are the same With wind along the sound path the up wind direction transit time increases and the down wind transit time decreases The wind speed is calculated from the measured transit times using the following formula Vy 0 5x Lx 1 t 1 tr where Vw Wind speed L Distance between the two transducers ts Transit time in forward direction t Transit time in reverse direction Measuring the six transit times allows Vw to be computed for each of the three ultrasonic paths The computed wind speeds are independent of altitude temperature and humidity which are cancelled out when the transit times are measured in both directions although the individual transit times depend on these parameters
