超聲風速儀的原理介紹

發布日期:2022-05-29 點擊率:65

    超聲波風速風向儀是利用發送聲波脈沖,測量接收端的時間或頻率(多普勒變換)差別來計算風速和風向的測量傳感器測量儀器


    超聲風速儀的工作原理:


    超聲測風是超聲波檢測技術在氣體介質中的一種應用它是利用超聲波在空氣中傳播速度受空氣流動(風) 的影響來測量風速的。


    與常規的風杯或旋翼式風速儀相比這種測量方法的大特點在于整個測風系統沒有任何機械轉動部件,屬于無慣性測量;


    故能準確測出自然風中陣風脈動的高頻成分,結合現代計算機技術,可在更高層次上揭示自然風的特性對于提高抗風減災能力和風資源的合理利用有重大意義。
