Abstract

PURPOSE:To seek an instantaneous wind velocity with high precision by performing a prearranged arithmetic operation using a period and a wave number against an input having more than a fixed period. CONSTITUTION:A control circuit 8 starts a counter for wave number measurement 2 and a counter for a period 4 following the rising of a signal waveform for an alternating current dynamo 1. If the value of the counter 4 reached a higher level of a fixed value, the circuit 8 transfers the content of the counter 2 to a latch circuit 3 and the content of the counter 4 to a latch circuit 6. After this process, the circuit 8 resets the counters 2 and 4 and repeats the same control. The outputs of the latch circuits 3, 6 and a proportional constant K are supplied to an arithmetic circuit 7, so that wind veclocity V is arithmetically operated on the formula V=KN/T (N means wave number, T a period).
