Extract

1. A simple inexpensive anemometer is described; the instrument is intended for general husbandry use.

2. The essential part of the apparatus is a 1 in. diameter electrically heated duralumin sphere capping a mercury-in-glass thermometer.

3. Charts are given relating wind-speed to sphere temperature, ambient temperature and heat input to the sphere. No further calibration is required.
