按照要求正確安裝后的橢圓齒輪流量計(jì)，使用時(shí)即可保證足夠的精度，通常累計(jì)值的精度可達(dá)0.5級(jí)，是一種較橢圓齒輪流量計(jì)為準(zhǔn)確的流量計(jì)量?jī)x表。但是，如果使用時(shí)被測(cè)介質(zhì)的流量過(guò)小，儀表的泄漏誤差的影響就會(huì)突出，不能再保證足夠的測(cè)量精度。因此，不同型號(hào)規(guī)格的橢圓齒輪流量計(jì)對(duì)zui小使用流量有一允許值，只有當(dāng)實(shí)際被測(cè)流量大于該下限流量允許值時(shí)，測(cè)量精度才能得到保證。 </p> <p> 其次，使用橢圓齒輪流量計(jì)要注意被測(cè)介質(zhì)的溫度不能過(guò)高，否則不僅會(huì)增加測(cè)量誤差，而且有使齒輪發(fā)生卡死的可能。為此，橢圓齒輪流量計(jì)在儀表所規(guī)定的使用溫度范圍內(nèi)使用。 </p> <p> 長(zhǎng)期使用后的橢圓齒輪流量計(jì)，其內(nèi)部的齒輪會(huì)被腐蝕和磨損，從而影響測(cè)量精度。因此，要經(jīng)常注意觀察，并定期拆下進(jìn)行檢查，若條件允許要定期進(jìn)行標(biāo)定。流量計(jì)價(jià)格查詢分流型浮子流量計(jì)的選用流速可比全流型高，液體流速可達(dá)2.5-3m/s，甚至高達(dá)4-5m/s。</p><div

2、測(cè)量管內(nèi)無(wú)阻礙流動(dòng)部件，無(wú)壓損，直管段要求較低。對(duì)漿液測(cè)量有獨(dú)特的適應(yīng)性； </p> <p> 3、合理選擇傳感器襯里和電極材料，即具有良好的耐腐蝕和耐磨損性； </p> <p> 4、轉(zhuǎn)換器采用新穎勵(lì)磁方式，功耗低、零點(diǎn)穩(wěn)定、精確度高。流量范圍度可達(dá)150：1； </p> <p> 5、轉(zhuǎn)換器可與傳感器組成一體型或分離型； </p> <p> 6、轉(zhuǎn)換器采用16位高性能微處理器，2x16LCD顯示，參數(shù)設(shè)定方便，編程可靠； </p> <p> 7、流量計(jì)為雙向測(cè)量系統(tǒng)，內(nèi)裝三個(gè)積算器：正向總量、反向總量及差值總量；可顯示正、反流量，并具有多種輸出：電流、脈沖、數(shù)字通訊、HART； </p> <p> 8、轉(zhuǎn)換器采用表面安裝技術(shù)(SMT)，具有自檢和自診斷功能； </p> <p> 9、測(cè)量精度不受流體密度、粘度、溫度、壓力和電導(dǎo)率變化的影響，傳感器感應(yīng)電壓信號(hào)與平均流速呈線性關(guān)系，因此測(cè)量精度高。 </p> <p> 10、測(cè)量管道內(nèi)無(wú)阻流件，因此沒(méi)有附加的壓力損失；測(cè)量管道內(nèi)無(wú)可動(dòng)部件，因此傳感器壽命極長(zhǎng)。 </p> <p> 11、由于感應(yīng)電壓信號(hào)是在整個(gè)充滿磁場(chǎng)的空間中形成的，是管道載面上的平均值，因此傳感器所需的直管段較短，長(zhǎng)度為5倍的管道直徑。 </p> <p> <br /> </p><p> 時(shí)差法測(cè)量順逆?zhèn)鞑r(shí)傳播速度不同引起的時(shí)差計(jì)算被測(cè)流體速度。 </p> <p> 它采用兩個(gè)聲波發(fā)送器(SA和SB)和兩個(gè)聲波jieshouqi超聲流量計(jì)(RA和RB)。同一聲源的兩組聲波在SA與RA之間和SB與RB之間分別傳送。它們沿著管道安裝的位置與管道成θ角(一般θ=45°)(圖1)。由于向下游傳送的聲波被流體加速，而向上游傳送的聲波被延遲，它們之間的時(shí)間差與流速成正比。也可以發(fā)送正弦信號(hào)測(cè)量?jī)山M聲波之間的相移或發(fā)送頻率信號(hào)測(cè)量頻率差來(lái)實(shí)現(xiàn)流速的測(cè)量。 </p> <p> 相位差法測(cè)量順逆?zhèn)鞑r(shí)傳播時(shí)由于時(shí)差引起的相位差計(jì)算速度。 </p> <p> 它的發(fā)送器沿垂直于管道的軸線發(fā)送一束聲波，由于流體流動(dòng)的作用，聲波束向下游偏移一段距離。偏移距離與流速成正比。流量計(jì)是測(cè)量液體、氣體流量必不可少的儀表。</p><div

src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637332519957626953/9160428.png"></div><p> 各種超聲流量計(jì)已廣用于工業(yè)生產(chǎn)、商業(yè)計(jì)量和水利檢測(cè)等方面，如:在市政行業(yè)的原水、自來(lái)水、中水、污水的計(jì)量中，超聲流量計(jì)具有大量程比、無(wú)壓損的特點(diǎn)，在保證測(cè)量準(zhǔn)確度的同時(shí)提高了管網(wǎng)的輸水效率;在水利水電行業(yè)的輸水管道、渠道、泵站、電站的流量計(jì)量中，超聲流量計(jì)具有大口徑、現(xiàn)場(chǎng)安裝、在線標(biāo)定的特點(diǎn)，使準(zhǔn)確測(cè)量成為可能。同時(shí)通過(guò)對(duì)水泵、水輪機(jī)單泵、單機(jī)的計(jì)量來(lái)實(shí)現(xiàn)設(shè)備優(yōu)化、經(jīng)濟(jì)運(yùn)行的目的;在工業(yè)冷卻循環(huán)水的計(jì)量中，超聲流量計(jì)實(shí)現(xiàn)了在線不斷流帶壓安裝和在線標(biāo)定;在商業(yè)計(jì)量方面多聲道超聲流量計(jì)已達(dá)到優(yōu)于(示值誤差)。(1)傳播時(shí)間法應(yīng)用于清潔、單相液體和氣體。典型應(yīng)用有工廠排放液、:怪液、液化天然氣等;(2)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(yàn);(3)多普勒法適用于異相含量不太高的雙相流體,例如: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。電磁流量計(jì)、超聲波流量計(jì)、渦街流量計(jì)利用電氣原理工作，從而避免了機(jī)械流量計(jì)工作中需要更換的運(yùn)動(dòng)機(jī)件。熱式質(zhì)量流量計(jì)聯(lián)系方式</p><p

流量計(jì)的選用主要參考流量范圍（L/h）、溫度（℃）、壓力（MPa）、口徑（mm）、黏度（mPa·s）、計(jì)量精度、腐蝕性、周圍工作環(huán)境、計(jì)算器形式等。 </p> <p> 2、流量計(jì)的安裝: </p> <p> 任何類型的流量計(jì)都有一定的安裝要求，只有正確安裝才能使流量計(jì)正常、準(zhǔn)確地運(yùn)行。流量計(jì)的安裝應(yīng)按產(chǎn)品使用說(shuō)明書(shū)的要求，結(jié)合安裝現(xiàn)場(chǎng)的實(shí)際情況，以zui合適的方式進(jìn)行。 </p> <p> 3、流量計(jì)的使用與維護(hù): </p> <p> 只有當(dāng)流量計(jì)正確使用并及時(shí)的維護(hù)時(shí)，流量計(jì)才能以規(guī)定的精度運(yùn)行。 </p> <p> （1）使用流量計(jì)時(shí)應(yīng)按照規(guī)定的流量范圍、工作壓力和工作溫度，不得隨意超出范圍以確保測(cè)量精度及使用壽命。 </p> <p> （2）對(duì)于運(yùn)行中的流量計(jì)，應(yīng)按時(shí)巡檢，并記錄有關(guān)運(yùn)行參數(shù)，如溫度、濕度、壓力、噪聲及有無(wú)滲漏等。 </p> <p> （3）長(zhǎng)時(shí)間不用的流量計(jì)應(yīng)將殼內(nèi)殘留的流體泄放掉，根據(jù)需要涂防腐劑。 </p> <p> （4）對(duì)于一些國(guó)家特定的流量計(jì)量?jī)x表，按規(guī)定按期強(qiáng)制標(biāo)定。熱式質(zhì)量流量計(jì)聯(lián)系方式</p><p
