style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山西孔板流量計廠家,流量計" src="https://tyunfile.71360.com/UploadFile/jszhck/637436289042998618/4460086.png"></div><p style="text-indent:25px"> 質量流量計安裝要求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部組態(tài)的流量方向一致。(注：質量流量計可以雙向使用。如果安裝方向與實際流向相反，修改變送器內的流向組態(tài)即可。)3、質量流量計是根據(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)。上海電磁流量計哪家比較便宜為了智能電磁流量計能夠很好地正常使用，智能電磁流量計傳感器接地一定要安裝好。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山西孔板流量計廠家,流量計" src="https://tyunfile.71360.com/UploadFile/jszhck/637436289060000603/4529138.png"></div><p> 測量流體流量的儀表統(tǒng)稱為流量計或流量表．流量計是工業(yè)測量中重要的儀表之一．隨著工業(yè)生產的發(fā)展，對流量測量的準確度和范圍的要求越來越高，流量測量技術日新月異．為了適應各種用途，各種類型的流量計相繼問世。目前已投入使用的流量計已超過100種。每種產品都有它特定的適用性,也都有它的局限性。按測量原理分有力學原理、熱學原理、聲學原理、電學原理、光學原理、原子物理學原理等。檢測件又可按其標準化程度分為二大類:標準的和非標準的。所謂標準檢測件是只要按照標準文件設計、制造、安裝和使用,無須經(jīng)實流標定即可確定其流量值和估算測量誤差。非標準檢測件是成熟程度較差的,尚未列入國際標準中的檢測件。 </p> <p> <br /> </p> <p> <br /> </p><p> 環(huán)形孔板適用于各種流體（氣體、蒸汽、液體）介質，它除了具有標準孔板的結構簡單、牢固、安裝使用方便等特點以外，還具有以下優(yōu)點： </p> <p> 1、更適合測量飽和蒸汽、過熱蒸汽以及煤氣、冷卻水等臟污流體。 </p> <p> 2、更容易適應高溫、高壓流體的流量測量。 </p> <p> 3、比圓缺孔板、偏心孔板工作更可靠，測量更精確。 </p> <p> 4、以較低的成本制成耐腐蝕型，測量腐蝕性流體的流量。 </p> <p> 5、由于本產品外部形狀簡單，容易制成夾套保濕型在夾套內通蒸汽，可以防止被測流體在測量管段內凝結或粘附；通以冷卻液，可防止易汽化的液體在流經(jīng)測流板時形成汽液兩相流。 </p> <p> 6、采用均壓環(huán)結構，減少了測量誤差來源引至差壓變送器的是在測流板上、下游處取壓管橫截面的靜壓平均值，減弱了上游局部阻力形成的速度分布畸變對精度的影響，實際精度更接近基本精度。 </p> <p> 7、要求較低的前后直管段 </p> <p> 8、采用一體型結構形式，減少管線敷設。 </p> <p> 9、采用帶遠傳膜盒的差壓變送器，可以測量諸如煤粉、渣油等臟污液體的流量。 </p> <p> 工作原理：環(huán)形孔板節(jié)流裝置和普通的標準孔板一樣，依據(jù)的基本原理是流體連續(xù)性方程和伯努利方程。把環(huán)形孔板安裝在圓管中，當液體流經(jīng)節(jié)流裝置時，其上、下游側之間就會產生壓力差。 </p> <p> 連接方式：法蘭連接和焊接連接。電磁流量計測量通道是段光滑直管,不會阻塞,適用于測量含固體顆粒的液固二相流體,如紙漿、泥漿、污水等;</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山西孔板流量計廠家,流量計"

style="text-indent:25px">測量液體流量時引壓管水平段應在同一水平面內；山西孔板流量計廠家</p><p> 電磁流量計的安裝與調試比其它流量計復雜，且要求更嚴格。變送器和轉換器必須配套使用，兩者之間不能用兩種不同型號的儀表配用。在安裝變送器時，從安裝地點的選擇到具體的安裝調試，必須嚴格按照產品說明書要求進行。安裝地點不能有振動，不能有強磁場。在安裝時必須使變送器和管道有良好的接觸及良好的接地。變送器的電位與被測流體等電位。在使用時，必須排盡測量管中存留的氣體，否則會造成較大的測量誤差。電磁流量計用來測量帶有污垢的粘性液體時，粘性物或沉淀物附著在測量管內壁或電極上，使變送器輸出電勢變化，帶來測量誤差，電極上污垢物達到一定厚度，可能導致儀表無法測量。
