style="text-indent:25px">量儀表(流量計(jì))的選型對儀表能否成功使用往往起著很重要的作用，由于被測對象的復(fù)雜狀況以及儀表品種繁多、性能指標(biāo)各使得儀表的選型感到困難，綿陽流量儀表，綿陽流量儀表。沒有一種十全十美的流量計(jì)，各類儀表都有各自的特點(diǎn)，選型的目的就是在眾多的品種中揚(yáng)長避短選擇自己**合適的流量計(jì)儀表。流量計(jì)儀表選型的步驟如下： 1，綿陽流量儀表、依據(jù)流體種類及五個(gè)方面考慮因素初選可用儀表類型(要有幾種類型以便進(jìn)行選擇)； 2、對初選類型進(jìn)行資料及價(jià)格信息的收集，為深入的分析比較準(zhǔn)備條件； 3、采用淘汰法逐步集中到1～2種類型，對五個(gè)方面因素要反復(fù)比較分析**終確定預(yù)選目標(biāo)。綿陽流量儀表</p><div

style="text-indent:25px">帶打印便攜超聲波流量計(jì)具有測量精度高、一致性好、電池供電、操作簡單、攜帶方便等特點(diǎn)，是目前國內(nèi)體積較小、質(zhì)量較輕，真正意義上的便攜超聲波流量計(jì)。利用了低電壓、多脈沖時(shí)差原理，采用高精度和超穩(wěn)定的雙平衡信號(hào)差分發(fā)射、差分接收數(shù)字檢測技術(shù)來測量順流和逆流方向的聲波傳輸時(shí)間，根據(jù)時(shí)差計(jì)算出流速。具有穩(wěn)定性好、零點(diǎn)漂移小、測量精度高，量程比寬抗干擾性強(qiáng)等特點(diǎn)。當(dāng)超聲波波束在液體中傳播時(shí)，液體的流動(dòng)將使傳播時(shí)間產(chǎn)生微小變化，其傳播時(shí)間的變化正比于液體的流速，零流量時(shí)，兩個(gè)傳感器發(fā)射和接受聲波所需的時(shí)間完全相同；介質(zhì)流動(dòng)時(shí)，逆流方向的志波傳輸時(shí)間大于水流方向的聲波傳輸時(shí)間。眉山流量儀表價(jià)格</p><div

style="text-indent:25px">根據(jù)一元流動(dòng)的連續(xù)方程，當(dāng)流通截面恒定時(shí)，截面上的平均流速與體積流量成正比，于是各種與流速有關(guān)的物理現(xiàn)象便可以用來建立流量計(jì)。例如：超聲波流量計(jì)、渦輪流量計(jì)、動(dòng)壓測量管、漩渦流量計(jì)和節(jié)流式流量計(jì)等均屬于此類。目前流量儀表中以這類儀表**多，它們有較寬的使用條件，有用于高溫高壓流體的，也有精度較高的，有的能量損失很小，有的可適應(yīng)臟污介質(zhì)等等。使流體流動(dòng)得到某種加速度的力學(xué)效應(yīng)與質(zhì)量的關(guān)系，是這種方法的物理基礎(chǔ)，按這種原理制成的流量計(jì)有質(zhì)量流量計(jì)和回轉(zhuǎn)管式流量計(jì)等。</p><p style="text-indent:25px">化工生產(chǎn)中所處理的物料大部分是流體，它們通過動(dòng)力設(shè)備，如鼓風(fēng)機(jī)、泵等，在管道中輸送。工業(yè)上用于測量流體流量的儀表叫做流量計(jì)或流量儀表、流量測量的重要目的有如下兩個(gè)方面； 1．流量不但是控制化工生產(chǎn)及監(jiān)督設(shè)備工況的重要參數(shù)，也是物料流動(dòng)工況特征參數(shù)之一，同時(shí)對確保正常生產(chǎn)，亦有很大意義。 2．流量又是車間、工廠實(shí)行企業(yè)經(jīng)濟(jì)核算的基礎(chǔ)依據(jù)，生產(chǎn)廠要準(zhǔn)確地測出水、蒸汽、燃料氣、原料或動(dòng)力消耗的情況，以加強(qiáng)企業(yè)管理。因此，操作人員對流量的測量，必須給予足夠的重視。由于流量測量的目的不同，對流量測量的要求也不同。前一種則要求儀表穩(wěn)定、靈敏，后一種則要求儀表準(zhǔn)確、可靠。</p><div

1、儀表性能方面：準(zhǔn)確度、重復(fù)性、線性度、范圍度、流量范圍、信號(hào)輸出特性、響應(yīng)時(shí)間、壓力損失等； 2、流體特性方面：溫度、壓力、密度、粘度、化學(xué)腐蝕、磨蝕性、結(jié)垢、混相、相變、電導(dǎo)率、聲速、導(dǎo)熱系數(shù)、比熱容，等熵指數(shù)； 3、安裝條件方面：管道布置方向，流動(dòng)方向，檢測件上下游側(cè)直管段長度、管道口徑，維修空間、電源、接地、輔助設(shè)備(過濾器、消氣器)、安裝、等； 4、環(huán)境條件方面：環(huán)境溫度、濕度、電磁干擾、安全性、防爆、管道振動(dòng)等； 5、經(jīng)濟(jì)因素方面：儀表購置費(fèi)、安裝費(fèi)、運(yùn)行費(fèi)、校驗(yàn)費(fèi)、維修費(fèi)、儀表使用壽命、備品備件等。南充流量儀表推薦</p><p style="text-indent:25px">綿陽流量儀表</p><p
