Wind speed
Wind speed is measured using an instrument called a wind meter. An anemometer or wind meter is a device that is used to measure windspeed. The wind meter used during this field trip is called an optoelectrionic anemometer which is a small hand held device. This device contains an exposed turbine wheel which is encased in an aluminium shell. When the wind turns the turbine, each time it breaks a light beam and generates an electronic current. An electronic circuit within the anemometer times the pulses and uses them to calculate the wind speed.
Materials:
- Optoelectronic anemometer
Method:
1. Turn the anemometer ON.
2. Hold the wind meter in the air until a reading is shown on the screen.
3. Read and record the indicated wind speed.
The wind speed recorded during this field study was 0.8m/s which fell
between the average of 0-2.0m/s.
