style="font-size:12px;">二次裝置為各種機械、電子、機電一體式差壓計,差壓變送器及流量顯示儀表。它已發(fā)展為三化(系列化、通用化及標準化)程度很高的、種類規(guī)格龐雜的一大類儀表,它既可測量流量參數(shù),也可測量其它參數(shù)(如壓力、物位、密度等)。</span><span

水平管道基本安裝方式對于水平管道，測量氣體時推薦安裝在管道上方160度范圍內(nèi)，尤其對于有大量水粉的氣體時，我們只推薦這樣安裝;測量液體時推薦安裝在管道下方160度范圍內(nèi)，尤其對于含有大量氣體的液體時，我們只推薦這樣安裝;但有一點要注意，對于那些極易氣化的液體，如液態(tài)的烯烴類介質(zhì)，安裝時插入方向同氣體，在管道上方。測量蒸汽時只推薦傳感器安裝在管道下方160度內(nèi)，并且要使傳感器處于整個測量裝置的比較高點。垂直管道基本安裝方式對于垂直管道，理論上可以在360度內(nèi)安裝。對于含有大量水分的濕氣體，推薦傳感器安裝時向上傾斜5度，如左圖所示。對于含有大量氣體的液體，推薦傳感器安裝時向下傾斜5度，如右圖所示。對于蒸汽，推薦傳感器安裝時下傾斜5度，如右圖，且傳感器應該處于整個測量系統(tǒng)中的比較高點。威力巴安裝所需直管段小直管段要求—彎管后2D安裝如圖所示。當管道上、下游的直管段不夠長時，我們推薦在彎管后2倍管道內(nèi)徑處安裝威力巴，因在彎管后的流體剖面較復雜，需將流體系數(shù)K做適當?shù)恼{(diào)整。調(diào)整K系數(shù)后，測量精度為±3%。 </p><p> 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。流量計傳感器上游也應該有一定的直管段，一般在5D~10D。</p><div

style="text-indent:25px">智能電磁流量計傳感器接地很重要，尤其在管道存在雜散電流干擾時，只有良好的接地保護，才能使智能電磁流量計準確地測量。也許在沒有這種干擾的環(huán)境里，不接地并不影響流量計準確測量，但是一旦環(huán)境改變，即造成流量計不能準確穩(wěn)定地工作，所以我們在安裝時比較好做好傳感器接地保護，給智能電磁流量計創(chuàng)造一個良好的工作環(huán)境。接地環(huán)分為普通型和保護型，一般是使用普通型，若被測介質(zhì)是磨損性的，宜使用帶頸的保護接地環(huán)。以保護進口端的襯里，延長使用壽命。若口徑在200mm以下的智能電磁流量計，選用聚四氟乙烯襯里時，應選用接地環(huán)，以保證在管道連接安裝時保護襯里不受損壞，接地環(huán)通常是不銹鋼或Hc合金的。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。常州插入式巴類流量計批發(fā)價格</p><p

質(zhì)量流量計安裝要求1、安裝位置的選擇應避免電磁干擾。傳感器、變送器的安裝位置以及電纜鋪設應盡量遠離易產(chǎn)生強電磁場的設備，如大功率馬達、變壓器設施、變頻設備等。2、質(zhì)量流量傳感器安裝應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相互平行，應使兩個法蘭的中心位于同一軸線避免產(chǎn)生附加應力。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)。常州插入式巴類流量計批發(fā)價格</p><p
