Effects of Barometric pressure and relative humidity on cup anemometers

The cup anemometer is essentially a differential drag device and is not sensitive to the effects of barometric pressure and relative humidity. As an example, if the cup anemometer was placed in water, the cups would still respond similar to the air.

It is the drag difference, not the fluid density that matters.
