流量計英文名稱是flowmeter，全國科學(xué)技術(shù)名詞審定委yuan會把它定義為：指示被測流量和（或）在選定的時間間隔內(nèi)流體總量的儀表。簡單來說就是用于測量管道或明渠中流體流量的一種儀表。流量計的特點(diǎn)：1、特有時間顯示及實時數(shù)據(jù)存儲之功能，無論什么情況，上海流量計哪里有現(xiàn)貨，都能保證內(nèi)部數(shù)據(jù)不會丟失，可長久性保存。2，上海流量計哪里有現(xiàn)貨、整機(jī)功耗極低，能憑內(nèi)部電池長期供電運(yùn)行，是理想的無需外電源就地顯示儀表。3、防盜功能可靠，具有密碼保護(hù)，防止參數(shù)改動，上海流量計哪里有現(xiàn)貨。4、具備兩線制和三線制4～20mA標(biāo)準(zhǔn)電流信號輸出，脈沖輸出和RS485接口。

質(zhì)量流量計分直接式和間接式兩種。直接式質(zhì)量流量計利用與質(zhì)量流量直接有關(guān)的原理進(jìn)行測量;間接式質(zhì)量流量計是用密度計與體積流量間接相乘求得質(zhì)量流量的。應(yīng)用：在現(xiàn)代工業(yè)生產(chǎn)中在高溫高壓的情況下，由于材質(zhì)和結(jié)構(gòu)等方面的原因，直接式質(zhì)量流量計的應(yīng)用遇到困難;而間接式質(zhì)量流量計由于密度受濕度和壓力適用范圍的限制，也不好實際應(yīng)用。典型應(yīng)用有工廠排放液、怪液、液化天然氣等;氣體應(yīng)用方面在高壓天然氣領(lǐng)域已有使用良好的經(jīng)驗;多普勒法適用于異相含量不太高的雙相流體，如未處理污水、工廠排放液、臟流程液，通常不適用于非常清潔的液體。
