Wind Vane
What’s the difference between a wind vane and a weathervane? The term ‘wind vane’ is just another name for the weather instrument that we all love and have come to call ‘weathervane’. They both do the same thing, that is, they both determine the source direction of a blowing wind so that weathervane users can accurately name any wind. How does the wind vane pointer work? The pointer is a carefully calibrated instrument that is correctly balanced in design and weight before manufacture. When there is a change in wind direction, the pointer will carefully rotate on its axis to rest in the source direction of that new blowing wind. This enables users to line up the pointer with the compass points below it in order to name the wind. What kind of weathervane pointers are available? Traditionally all weathervane pointers were either roosters or arrows, but nowadays you can get just about any design to suit your personality. You can get sophisticated herons and eagles, or fun witches, wizards and even a dancing pig with a martini glass!
