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(diǎn)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)儀表由懸浮粒或氣泡造成的堵塞、磨損、附著而不能運(yùn)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(shí)踐中摸索經(jīng)驗(yàn)，積累經(jīng)驗(yàn)。單電機(jī)傳動時，液力偶合器的充液量為9升，雙電機(jī)傳動時為了保證兩電機(jī)的實(shí)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(jī)的實(shí)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(shí)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(shí)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(shí)現(xiàn)了負(fù)載的四象限運(yùn)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(diǎn)已成為應(yīng)用熱點(diǎn)。
不但自帶數(shù)據(jù)庫可實(shí)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(yùn)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(shí)現(xiàn)了在無電力供給環(huán)境下，或是獨(dú)立自成計(jì)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(jī)連貫，履行數(shù)字旌旗燈號傳輸上傳表示，也或是在工控機(jī)上履行二次數(shù)據(jù)處理，組成的計(jì)量零碎更加靈動、牢靠。采納這種法子，實(shí)現(xiàn)了計(jì)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(hù)衛(wèi);不但或是單校也或是聯(lián)校。
