質zhi量liang流liu量liang計ji是shi一yi種zhong常chang用yong的de流liu量liang測ce量liang儀yi器qi，直zhi接jie測ce量liang通tong過guo流liu量liang計ji的de介jie質zhi的de質zhi量liang流liu量liang
，還hai可ke測ce量liang介jie質zhi的de密mi度du及ji間jian接jie測ce量liang介jie質zhi的de溫wen度du。它ta的de應ying用yong廣guang泛fan，在zai很hen多duo領ling域yu中zhong都dou有you廣guang泛fan的de應ying用yong，那na麼me你ni知zhi道dao質zhi量liang流liu量liang計ji是shi怎zen樣yang測ce量liang液ye氨an的de麼me?

一yi般ban來lai說shuo，測ce量liang液ye氨an的de方fang式shi是shi利li用yong科ke裏li奧ao利li力li原yuan理li。當dang沒mei有you液ye體ti流liu過guo兩liang段duan平ping行xing安an裝zhuang並bing以yi一yi定ding頻pin率lv振zhen動dong著zhe的de流liu量liang管guan時shi，流liu量liang管guan不bu產chan生sheng扭niu振zhen，管guan兩liang邊bian信xin號hao檢jian測ce器qi輸shu出chu的de兩liang個ge檢jian測ce信xin號hao是shi同tong相xiang位wei的de;當dang有you流liu體ti流liu過guo流liu量liang管guan時shi
，流liu量liang管guan在zai科ke裏li奧ao利li力li的de作zuo用yong下xia產chan生sheng扭niu振zhen，從cong而er導dao致zhi管guan兩liang邊bian信xin號hao檢jian測ce器qi輸shu出chu的de兩liang個ge檢jian測ce信xin號hao存cun在zai相xiang位wei差cha，這zhe個ge相xiang位wei差cha直zhi接jie正zheng比bi於yu流liu過guoT型流量管的質量流量。

由於流量計安裝位置正處於循環機、大型壓縮機的包圍圈中，大電機啟動時，會引起電網電壓的波動
，為保證流量計T型管的諧振頻率穩定在80Hz，振幅小於1mm，需要保證驅動線圈的電壓頻率穩定，為此，在儀表電源安裝中，增加了1台交流穩壓器。

由you於yu使shi用yong質zhi量liang流liu量liang計ji來lai測ce量liang液ye氨an的de方fang式shi結jie束shu了le幾ji十shi年nian來lai，生sheng產chan液ye氨an產chan量liang計ji量liang靠kao液ye氨an儲chu罐guan玻bo璃li液ye位wei計ji來lai計ji算suan的de曆li史shi
，同tong時shi，因yin流liu量liang計ji的de準zhun確que計ji量liang，化hua解jie了le各ge分fen廠chang之zhi間jian因yin液ye氨an計ji量liang靠kao分fen攤tan而er引yin起qi的de矛mao盾dun糾jiu紛fen，也ye減jian少shao了le儀yi表biao的de工gong作zuo量liang和he維wei護hu量liang。
