一般說來由于工業(yè)生產(chǎn)中工質(zhì)的溫度常不能保持恒定，故多采用頻差法及時差法。只有在管徑很大時才采用直接時差法。對換能器安裝方法的選擇原則一般是：當(dāng)流體沿管軸平行流動時，選用Z法；當(dāng)流動方向與管鈾不平行或管路安裝地點使換能器安裝間隔受到限制時，采用V法或X法。當(dāng)流場分布不均勻而表前直管段又較短時，也可采用多聲道(雙聲道或四聲道)來克服流速擾動帶來的流量測量誤差。多普勒法適于測量兩相流，可避免常規(guī)儀表由懸浮?；驓馀菰斐傻亩氯?、磨損、附著而不能運行的弊病，因而得以迅速發(fā)展。
直線振動篩總之，膠帶調(diào)偏是一件比較麻煩的事情，影響膠帶跑偏的因素很多，需要仔細(xì)觀察，分析原因，然后對癥下藥。調(diào)偏工作也需要在實踐中摸索經(jīng)驗，積累經(jīng)驗。單電機傳動時，液力偶合器的充液量為9升，雙電機傳動時為了保證兩電機的實際功率分配相接近，必須通過調(diào)正來確定合理的充液量使兩電機的實際功率(或電流)之比接近于4/4的比值。
一般的交-直-交電壓型變頻器的主電路輸入側(cè)是經(jīng)三相橋式不可控整流器向中間直流環(huán)節(jié)的濾波電容充電，然后通過PWM控制下的逆變器輸入到負(fù)載上。雖然這樣的電路成本低、結(jié)構(gòu)簡單、可靠性高，但是由于采用三相橋式不可控整流器，使得功率因數(shù)低、網(wǎng)側(cè)諧波污染以及無法實現(xiàn)能量的再生利用等。PWM+PWM（四象限矢量控制結(jié)構(gòu)）控制技術(shù)打破了過去變頻器的統(tǒng)一結(jié)構(gòu)，PWM整流器和PWM逆變器通過軟硬件的調(diào)整和電抗器等附件就可實現(xiàn)系統(tǒng)的功率因數(shù)趨于1，大幅消除了網(wǎng)側(cè)諧波污染，綠色環(huán)保，并且實現(xiàn)了負(fù)載的四象限運行，使能量雙向流動，能量轉(zhuǎn)換效率高，能滿足低壓大功率及高壓大功率的要求等特點已成為應(yīng)用熱點。
不但自帶數(shù)據(jù)庫可實現(xiàn)瞬時參數(shù)及流量的表示，以及積累流量和歷史數(shù)據(jù)的再現(xiàn);并且在儀表的運行方面，采取了多種電源保障法子:內(nèi)電池組、太陽能和外接電源等，實現(xiàn)了在無電力供給環(huán)境下，或是獨立自成計量零碎，就地表示人造氣瞬時流量、積累流量和數(shù)據(jù)的存儲、再現(xiàn)等;正常環(huán)境下可顛末現(xiàn)場總線和上位機連貫，履行數(shù)字旌旗燈號傳輸上傳表示，也或是在工控機上履行二次數(shù)據(jù)處理，組成的計量零碎更加靈動、牢靠。采納這種法子，實現(xiàn)了計量數(shù)據(jù)的無憂化，使得零碎組織簡單、操縱更簡單、更牢靠、更容易護衛(wèi);不但或是單校也或是聯(lián)校。
