5. ng a measurement of the wind velocity it may occur that the measuring beam sonic wave between LS and MIC is interrupted due to an object which unexpectedly came between the transducers or due to a bad connection at installation of WindSpeed In case of an interruption of the sonic wave the measuring box of WindSpeed will render a short beep tone via a built in loudspeaker However the WindSpeed program is developed in such a way that this temporary interruption will be ignored in the final result provided that the interruption does not disturb the measuring period 4 8 Lifetime of battery With a new 12Vdc battery version 2010 the WindSpeed configuration can be operated for 100 hours TimeTronics 5 2012v1 Manual WindSpeed Copyright 2012 TimeTronics All rights reserved TimeTronics Lammerdries 23b B 2250 Olen Belgium Tel 32 0 14 23 19 11 Fax 32 0 14 23 20 24 ICE 7
6. tem which uses a propeller or rotating paddle wheel 1 2 Disadvantages of a paddle wheel To measure minor wind velocities a paddle wheel with a large surface and a very small friction is required which at the same time causes certain inertia A short and powerful blast of wind suddenly brings the wheel to a number of revolutions After the blast of wind has suddenly come to a standstill the paddle wheel keeps on turning for only the friction of the surrounding air will slow it down Due to the fact that these rotations are calculated within the result the average wind velocity will be automatically increased Moreover rotating parts are generally subject to wear Therefore a good alternative for this paddle wheel is the TimeTronics sonic anemometer or WindSpeed 2 PRINCIPLE A sonic wave is sent via from a minuscule loudspeaker to a tiny microphone As oe sound MIC MIC is generally known the speed of sound approximately measures 341 m s Je LS which is directly related to the medium of surrounding air p wind Sa mn sound In case this medium would start moving the sound which drifts with the wind will arrive at the MIC a little sooner than the sound which has to travel against the wind By measuring and registering the difference in speed between the sonic waves which are travelling along with the wind and the ones which are travelling against it we can very accurately determine the wind
