由于流體的容積受溫度、壓力等參數(shù)的影響，用容積流量表示流量大小時需給出介質(zhì)的參數(shù)。在介質(zhì)參數(shù)不斷變化的情況下，往往難以達到這一要求，而造成儀表顯示值失真。因此，質(zhì)量流量計就得到的應(yīng)用和重視。質(zhì)量流量計分直接式和間接式兩種。直接式質(zhì)量流量計利用與質(zhì)量流量直接有關(guān)的原理進行測量，目前常用的有量熱式、角動量式、振動陀螺式、馬格努斯效應(yīng)式和科里奧利力式等質(zhì)量流量計。間接式質(zhì)量流量計是用密度計與容積流量直接相乘求得質(zhì)量流量的。淮安長頸噴嘴流量計批發(fā)價格質(zhì)量流量計額安裝時建議在流量計進口處加過濾器。</p><div

如果在測量區(qū)內(nèi)有穩(wěn)態(tài)的渦流則會影響測量的穩(wěn)定性和測量的精度，這時可以增加前后直管段的長度、采用一個流量穩(wěn)定器或減少測量點的截面以穩(wěn)定流速分布。流量計可以水平和垂直安裝，但是應(yīng)該確保避免沉積物和氣泡對測量電極的影響，電極軸向保持水平為好。垂直安裝時，流體應(yīng)自下而上流動。傳感器不能安裝在管道的比較高位置，這個位置容易積聚氣泡。 </p> <p> 確保流量傳感器在測量時，管道中充滿被測流體，不能出現(xiàn)非滿管狀態(tài)。如管道存在非滿管或是出口有放空狀態(tài)，傳感器應(yīng)安裝在一根虹吸管上。 </p> <p> 電磁流量計的常規(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><p> 質(zhì)量流量計安裝要求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)盡量遠離易產(chǎn)生強電磁場的設(shè)備，如大功率馬達、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)使傳感器流向標識與流體流向一致。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)量流量計可以雙向使用。如果安裝方向與實際流向相反，修改變送器內(nèi)的流向組態(tài)即可。)3、質(zhì)量流量計是根據(jù)測量管振動原理測量的流量儀表，因此傳感器安裝時應(yīng)考慮在兩側(cè)的工藝管道近法蘭處(約2～10倍管徑處)做堅固的支撐，避免儀表及相關(guān)管路產(chǎn)生震動。若強烈的管道振動不可避免時，建議用柔性管將管道系統(tǒng)與儀表傳感器隔離。4、因質(zhì)量流量計是依據(jù)科氏力原理工作的，為避免重力對計量精度的影響。質(zhì)量流量計的測量管無論是向上還是向下安裝，都要盡量使測量管與地平面保持垂直或水平。5、安裝時連接法蘭面應(yīng)相互平行，應(yīng)使兩個法蘭的中心位于同一軸線避免產(chǎn)生附加應(yīng)力。嚴禁用傳感器硬行拉直上、下游工藝管道，否則將影響測量甚至損壞傳感器。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、日常維護及確保傳感器在不工作時亦可處于滿管狀態(tài)。孔板流量計安裝時應(yīng)配有一段測量管,至少保持**DN、后5DN的等徑直管段，以提高測量精度。</p><div

工作原理：根據(jù)流體振蕩原理來測量流量的，流體在管道中經(jīng)過渦街流量變送器時，在三角柱的旋渦發(fā)生體后上下交替產(chǎn)生正比于流速的兩列旋渦，旋渦的釋放頻率與流過旋渦發(fā)生體的流體平均速度及旋渦發(fā)生體特征寬度有關(guān)，根據(jù)這種關(guān)系，旋渦頻率就可以計算出流過旋渦發(fā)生體的流體平均速度，再乘以橫截面積得到流量。 </p> <p> 工作特點：①結(jié)構(gòu)簡單而牢固，無可動部件，可靠性高，長期運行十分可靠;②安裝簡單，維護十分方便;③檢測傳感器不直接接觸被測介質(zhì)，性能穩(wěn)定，壽命長;④輸出是與流量成正比的脈沖信號，無零點漂移，精度高;⑤測量范圍寬，量程比可達1：10;⑥壓力損失較小，運行費用低，更具節(jié)能意義。直接式質(zhì)量流量計利用與質(zhì)量流量直接有關(guān)的原理進行測量；淮安長頸噴嘴流量計批發(fā)價格</p><p

差壓式流量計是一類應(yīng)用的流量計,在各類流量儀表中其使用量占居**。近年來,由于各種新型流量計的問世,它的使用量百分數(shù)逐漸下降,但目前仍是重要的一類流量計。 </p> <p> 優(yōu)點: </p> <p> (1)應(yīng)用多的孔板式流量計結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長; </p> <p> (2)應(yīng)用范圍,至今尚無任何一類流量計可與之相比擬; </p> <p> (3)檢測件與變送器、顯示儀表分別由不同廠家生產(chǎn),便于規(guī)模經(jīng)濟生產(chǎn)。 </p> <p> 缺點: </p> <p> (1)測量精度普遍偏低;<span style="display:none;"></span> </p> <p> (2)范圍度窄,一般* 3:1~4:1;
