• Cup anemometer (3cups)
Velocity anemometer“John Patterson ”
Advantages:- Error of less than 3% up to 60 mph- Produced maximum torque when it was at
45° to the wind flow.- Had a more constant torque - Responded more quickly

• Ultrasonic wind sensors (Advantages)
1. not affected by inertia
2. Measure sudden change
3. More accurate
4. Less parts
5. More resisting on ice and weather conditions
