A vertical marking device is described, capable of being assembled in any area where needed, by means of which a precise indication of the direction and the speed of the prevailing wind is provided for the purpose of knowing the degree of risk its speed implies. The marking device has a vertical support pole to which a rotating bushing is associated with respect to the pole shaft, supporting a vertically positioned indicator element or sign, which in turn supports one or more anemometric arrows, preferably two, one on each side of the body, joined together and capable of simultaneous rotation in the vertical plane by means of pivoting with respect to the pin which joins them on their upper respective end, and which crosses through the body in a position close to its innermost, upper corner. The body of the indicator element or sign incorporates an arrow element on its upper horizontal edge, with the arrowhead towards the inside, and it also has the lateral sides with impressions dividing them into differently colored sectors, also being able to include direct reading numerical values. <IMAGE> |
