The Gill UVW Anemometer Model 27005 measures the three orthogonal vectors of the wind: along wind component "U", across wind component "V", and vertical wind component "W".
The three Propeller Anemometer sensors are mounted at right angles on a common mast. Each sensor measures the wind component parallel with its axis of rotation. Propeller response as a function of wind angle approximates the cosine law, allowing true wind velocity and direction to be calculated. The UVW Anemometer is designed for maximum sensitivity at lower wind speeds. Optional carbon fiber thermoplastic (CFT) propellers are available for applications requiring greater range and durability. Rain and dust are excluded from the precision bearings by a continuous duty air blower that keeps the instrument under a slight positive pressure. For single axis applications, individual propeller anemometers are available separately (see Model 27106)

The Gill Propeller Anemometer Model 27106 is a precision, single axis wind measuring instrument.
The Gill Propeller Anemometer utilizes a fast response helicoid propeller and high quality tach-generator transducer to produce a DC voltage that is linearly proportional to air velocity. Airflow from any direction may be measured, however, the propeller responds only to the component of the air flow which is parallel to its axis of rotation. Off-axis response closely approximates a cosine curve with appropriate polarity; with perpendicular air flow, the propeller does not rotate. The output signal is suitable for a wide range of signal translators and data logging devices. The standard expanded polystyrene (EPS) propeller offers maximum sensitivity at low wind speeds. An optional carbon fiber thermoplastic (CFT) propeller is available for greater range and durability.
