Hi,

Note that the Fine Offset Anemometer generates TWO clicks (pulses) per revolution! So you need to be very careful whether pulses or revolutions are being specified, Also, the FO transmitter counts over a period of two seconds, so the minimum resolution is 0.75 mph, or one revolution/second corresponds to 3 mph (approximately 1.3 m/s or just under 5 km/hr). Many users seem to believe that their FO anemometer under-reads, but measurements suggest that actually they over-read !

Cheers, Alan.
