超聲波流量計(jì)缺點(diǎn):（1）超聲波流量計(jì)的溫度測(cè)量范圍不高，一般只能測(cè)量溫度低于200℃的流體。（2）抗干擾能力差。易受氣泡、結(jié)垢、泵及其它聲源混入的超聲雜音干擾、影響測(cè)量精度。（3）直管段要求嚴(yán)格，為前**,后5D。否則離散性差，測(cè)量精度低。（4）安裝的不確定性，湖南插入式巴類流量計(jì)批發(fā)價(jià)格，會(huì)給流量測(cè)量帶來較大誤差。（5）測(cè)量管道因結(jié)垢，湖南插入式巴類流量計(jì)批發(fā)價(jià)格，會(huì)嚴(yán)重影響測(cè)量準(zhǔn)確度，帶來明顯的測(cè)量誤差，湖南插入式巴類流量計(jì)批發(fā)價(jià)格，甚至在嚴(yán)重時(shí)儀表無流量顯示（6）可靠性、精度等級(jí)不高（一般為1.5～2.5級(jí)左右），重復(fù)性差。（7）使用壽命短（一般精度只能保證一年）。

質(zhì)量流量計(jì)安裝要求1、安裝位置的選擇應(yīng)避免電磁干擾。傳感器、變送器的安裝位置以及電纜鋪設(shè)應(yīng)盡量遠(yuǎn)離易產(chǎn)生強(qiáng)電磁場(chǎng)的設(shè)備，如大功率馬達(dá)、變壓器設(shè)施、變頻設(shè)備等。2、質(zhì)量流量傳感器安裝應(yīng)使傳感器流向標(biāo)識(shí)與流體流向一致。并使箭頭指向與變送器內(nèi)部組態(tài)的流量方向一致。(注：質(zhì)量流量計(jì)可以雙向使用。如果安裝方向與實(shí)際流向相反，修改變送器內(nèi)的流向組態(tài)即可。)3、質(zhì)量流量計(jì)是根據(jù)測(cè)量管振動(dòng)原理測(cè)量的流量?jī)x表，因此傳感器安裝時(shí)應(yīng)考慮在兩側(cè)的工藝管道近法蘭處(約2～10倍管徑處)做堅(jiān)固的支撐，避免儀表及相關(guān)管路產(chǎn)生震動(dòng)。若強(qiáng)烈的管道振動(dòng)不可避免時(shí)，建議用柔性管將管道系統(tǒng)與儀表傳感器隔離。4、因質(zhì)量流量計(jì)是依據(jù)科氏力原理工作的，為避免重力對(duì)計(jì)量精度的影響。質(zhì)量流量計(jì)的測(cè)量管無論是向上還是向下安裝，都要盡量使測(cè)量管與地平面保持垂直或水平。5、安裝時(shí)連接法蘭面應(yīng)相互平行，應(yīng)使兩個(gè)法蘭的中心位于同一軸線避免產(chǎn)生附加應(yīng)力。嚴(yán)禁用傳感器硬行拉直上、下游工藝管道，否則將影響測(cè)量甚至損壞傳感器。6、在傳感器的上、下游管道上，建議安裝截止閥及旁路以方便調(diào)零、日常維護(hù)及確保傳感器在不工作時(shí)亦可處于滿管狀態(tài)。</p><p style="text-indent:25px">電磁流量計(jì)是根據(jù)法拉弟電磁感應(yīng)定律制成的一種測(cè)量導(dǎo)電性液體的儀表。電磁流量計(jì)有一系列優(yōu)良特性,可以解決其它流量計(jì)不易應(yīng)用的問題,如臟污流、腐蝕流的測(cè)量。變送器的測(cè)量信號(hào)為很小的毫伏級(jí)電勢(shì)信號(hào)，除流量信號(hào)外，還夾雜一些與流量無關(guān)的信號(hào)，如同相電壓、正交電壓及共模電壓等。為了準(zhǔn)確測(cè)量流量，必須消除各種干擾信號(hào)，有效放大流量信號(hào)。應(yīng)該提高流量轉(zhuǎn)換器的性能，比較好采用微處理機(jī)型的轉(zhuǎn)換器，用它來控制勵(lì)磁電壓，按被測(cè)流體性質(zhì)選擇勵(lì)磁方式和頻率，可以排除同相干擾和正交干擾。但改進(jìn)的儀表結(jié)構(gòu)復(fù)雜，成本較高。電磁流量計(jì)的常規(guī)直管段要求是**D后5D，在有彎管、閥門的情況分別有不同的要求。</p><div

style="text-indent:25px">長(zhǎng)期以來,孔板流量計(jì)由于其技術(shù)成熟、標(biāo)準(zhǔn)化程度高、結(jié)構(gòu)簡(jiǎn)單、維護(hù)方便等特點(diǎn)而被地應(yīng)用。在海洋石油工程中也常常會(huì)用到孔板流量計(jì)。以采油平臺(tái)的測(cè)試分離器氣體出口測(cè)量為例,由于該介質(zhì)為氣體,一般壓力較高,介質(zhì)成分較復(fù)雜,流量范圍隨著年份變化較大等特點(diǎn),決定了該場(chǎng)合應(yīng)用孔板流量計(jì)為合適。尤其近年出現(xiàn)的可更換孔板更是解決了原有孔板流量計(jì)的低量程比的缺點(diǎn)而被地應(yīng)用。但是可更換的孔板價(jià)格昂貴,一般至少為同管徑孔板流量計(jì)價(jià)格的5倍以上。那么有沒有更好的產(chǎn)品來代替它,我們認(rèn)為V錐流量計(jì)就是代替它的優(yōu)先產(chǎn)品。湖南插入式巴類流量計(jì)批發(fā)價(jià)格</p></p><br
