The wind blowing into the cups causes the spindle to rotate. In standard instruments the design of the cups is such that the rate of rotation is proportional to the speed of the wind to a sufficiently close approximation. At intervals of no longer than five years, anemometers are calibrated in a wind tunnel to identify any departures in the relationship between spindle rotation and wind speed specified by the manufacturer. Calibration corrections are applied to the measured wind speed.\u003c\/p\u003e","brand":"RW Munro","offers":[{"title":"Default Title","offer_id":56995695591799,"sku":null,"price":159.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0303\/5122\/8972\/files\/Vintage_Munro_MkII_Counter_Three_Cup_Anemometer_Met_Reference_Number_2765.jpg?v=1775829148"},{"product_id":"vintage-white-bakelite-smiths-bimetallic-thermometer","title":"Vintage White Bakelite Smiths Bimetallic Thermometer","description":"\u003ch1\u003eVintage White Bakelite Smiths Bimetallic Thermometer\u003c\/h1\u003e\n\u003cp\u003eThis is a very unusual 1940s Vintage White Bakelite Smiths Bimetallic Thermometer.
