The measurement of rapidly fluctuating air flows.

Describes the development of an anemometer for the measurement of rapidly fluctuating air flows. Describes the B.R.E. shielded hot wire anemometer. Discusses modifications made to this anemometer to improve its response by using different shields and moving sensor wires closer together. Outlines system for processing signals from the anemometer using a micro-computer. Gives results of performance tests. Gives simple applications of theinstrument.
