The Turbometer

The Turbometer is based on the principle that a freely turning turbine will rotate at a speed directly proprtional to the wind speed.
This rotation is sensed by an infrared light beam, and the electronic signal is processed by an integrated circuit.

The instrument is robust enough for student use provided it is not

  • dropped or
  • allowed to get wet.
If you should have an accident, please report it to the staff. Accidents happen, and we will only be cross if we find out later, especially if you got the meter wet and it is too late to rinse and dry it.

The meter records in knots. 0.55 knots = 1 km/hr
