ABSTRACT:
An anemometer comprises an array (10) of piezoelectric pressure sensors (12), each of the sensors being mounted (e.g., on a circular mast 14) to face into a different wind direction. Electrical means are used to address each of the sensors (via contact wires (26, 28) for determining which of the sensors is generating, within a given time period, the greatest output voltage, thereby indicating the direction of the wind during such time period. In one arrangement, the amplitude of such greatest output voltage is used, via a look-up table, to determine the speed of the wind during such time period. In another arrangement, a separate, additional sensor is used to determine the wind speed.
