     0至100m/s的流速測量範圍可以分為三個區段：低速：0至5m/s；中速：5至40m/s；高速：40至100m/s
，但是風向風速監測儀之能夠進行測定低速以及中速的風向風速。風向風速記錄儀的熱敏式探頭用於0至5m/s的精確測量；風向風速監測儀的轉輪式探頭測量5至40m/s的流速效果最理想；而(er)利(li)用(yong)皮(pi)托(tuo)管(guan)則(ze)可(ke)在(zai)高(gao)速(su)範(fan)圍(wei)內(nei)得(de)到(dao)最(zui)佳(jia)結(jie)果(guo)。正(zheng)確(que)選(xuan)擇(ze)風(feng)向(xiang)風(feng)速(su)儀(yi)的(de)流(liu)速(su)探(tan)頭(tou)的(de)一(yi)個(ge)附(fu)加(jia)標(biao)準(zhun)是(shi)溫(wen)度(du)
