style="text-indent:25px">在歐洲和美國渦輪流量計是繼孔板流量計之后的第二個法定天然氣流量計，已經(jīng)發(fā)展為多品種、全系列，多規(guī)格，批量生產(chǎn)規(guī)模的天然氣流量計。標準規(guī)范亦十分完備，但亦有不足之處：對測量介質(zhì)潔凈度要求較高，使用期限受到限制。不過據(jù)國外使用部門稱：曾對240臺使用8~15年的流量計進行周期檢定，發(fā)現(xiàn)儀表準確度的偏移仍在規(guī)定范圍內(nèi)。另外，采用一種***整流作用的整流器與渦輪流量傳感器耦合成結(jié)構(gòu)一體化的氣體渦輪流量計，達州渦輪流量計批發(fā)，達州渦輪流量計批發(fā)，達州渦輪流量計批發(fā)，在上游側(cè)阻流件為彎頭或有半開截止閥條件下，只需要2D直管段長度，對于城市用安裝空間窄小的，它是很突出的特點。達州渦輪流量計批發(fā)</p><div

智能液體渦輪流量計是采用先進的**功耗單片微機技術(shù)研制的渦輪流量傳感器與顯示積算一體化的新型智能儀表，具有機構(gòu)緊湊、讀數(shù)直觀清晰、可靠性高、不受外界電源干擾、抗雷擊、成本低等明顯優(yōu)點。 </p> <p> 采用渦輪進行測量的流量計。它先將流速轉(zhuǎn)換為渦輪的轉(zhuǎn)速，再將轉(zhuǎn)速轉(zhuǎn)換成與流量成正比的電信號。這種流量計用于檢測瞬時流量和總的積算流量，其輸出信號為頻率，易于數(shù)字化。圖中感應線圈和長久磁鐵一起固定在殼體上。當鐵磁性渦輪葉片經(jīng)過磁鐵時，磁路的磁阻發(fā)生變化，從而產(chǎn)生感應信號。信號經(jīng)放大器放大和整形，送到計數(shù)器或頻率計，顯示總的積算流量。同時將脈沖頻率經(jīng)過頻率－電壓轉(zhuǎn)換以指示瞬時流量。葉輪的轉(zhuǎn)速正比于流量，葉輪的轉(zhuǎn)數(shù)正比于流過的總量。渦輪流量計的輸出是頻率調(diào)制式信號，不僅提高了檢測電路的抗干擾性，而且簡化了流量檢測系統(tǒng)。它的量程比可達10:1，精度在±0.2%以內(nèi)。慣性小而且尺寸小的渦輪流量計的時間常數(shù)可達0.01秒。綿陽渦輪流量計哪家好</p><div

旋渦流量計是速度式流量計中的主要種類,當被測流體流過渦輪流量計傳感器時，在流體的作用下，葉輪受力旋轉(zhuǎn)，其轉(zhuǎn)速與管道平均流速成正比，同時，葉片周期性地切割電磁鐵產(chǎn)生的磁力線，改變線圈的磁通量，根據(jù)電磁感應原理，在線圈內(nèi)將感應出脈動的電勢信號，即電脈沖信號，此電脈動信號的頻率與被測流體的流量成正比。 </p> <p> 各種流量計中渦輪流量計、容積式流量計和科氏質(zhì)量流量計是三類重復性、精確度比較好的產(chǎn)品，而渦輪流量計又具有自己的特點，如結(jié)構(gòu)簡單、加工零部件少、重量輕、維修方便、流通能力大（同樣口徑可通過的流量大）和可適應高參數(shù)（高溫、高壓和低溫）等。至今，這類流量計產(chǎn)品可達技術(shù)參數(shù)：口徑4-750mm，壓力達250MPa，溫度為-240-700℃，像這樣的技術(shù)參數(shù)其他兩類流量計則是難以達到的。 </p><p> 應用： </p> <p> 在工業(yè)鍋爐進行的實際情況下，限于各種條件的制約，工業(yè)鍋爐的給水一般為隨時間負荷變化的間歇式的給水方式，這種方式?jīng)Q定了在鍋爐上水的主管道管路內(nèi)的流動體，即上水的流動通常表現(xiàn)為紊流的流動過程，即工業(yè)鍋爐的管道內(nèi)的水流為不規(guī)則的一邊相互混合一邊流動的狀態(tài)，而準確的計量工業(yè)鍋爐的給水流量和溫度，對于正確地分析熱平衡測試結(jié)果是十分關(guān)鍵的。渦輪流量計正是由于有數(shù)字信號輸出，相應度靈敏才可準確的準時的響應水流的紊流變化。在一個時間周期內(nèi)，工業(yè)鍋爐上水管道的流量為管道截面積F的積分，即Q=∫FVDF，而其他原理的流量計是很難達到渦輪流量計的高精度的。
