綜合吸收發(fā)達國家先進技術(shù)和總結(jié)多年研究生產(chǎn)經(jīng)驗的基礎(chǔ)上進行精心設(shè)計的產(chǎn)品，實現(xiàn)了產(chǎn)品智能化、標準化、系列化、通用化、生產(chǎn)模具化、確保產(chǎn)品質(zhì)量的美觀性。該產(chǎn)品具有電路先進、功耗微低、量程比寬、結(jié)構(gòu)簡單、阻力損失小、堅固耐用、用途廣、使用壽命長、工作穩(wěn)定，廣元渦街流量計、便于安裝調(diào)試等特點，廣元渦街流量計。 </p> <p> <p> 原理 </p> <p> 在流體中設(shè)置三角柱型旋渦發(fā)生體，則從旋渦發(fā)生體兩側(cè)交替地產(chǎn)生有規(guī)則的旋渦，廣元渦街流量計，這種旋渦稱為卡門旋渦，旋渦列在旋渦發(fā)生體下游非對稱地排列。 </p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />

src="http://tyunfile.71360.com/UploadFile/cdwckj/637107349011669922/7256332.jpg"></div><p> 特點 </p> <p> 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。 </p> <p> 2、安裝簡單，維護十分方便。 </p> <p> 3、檢測傳感器不直接接觸被測介質(zhì)，性能穩(wěn)定，壽命長。 </p> <p> 4、輸出是與流量成正比的脈沖信號，無零點漂移，精度高。 </p> <p> 5、測量范圍寬，量程比可達1：10。壓力損失較小，運行費用低，更具節(jié)能意義。 </p> <p> 6、在一定的雷諾數(shù)范圍內(nèi),輸出信號頻率不受流體物理性質(zhì)和組份變化的影響，儀表系數(shù)*與旋渦發(fā)生體的形狀和尺寸有關(guān)，測量流體體積流量時無需補償，調(diào)換配件后一般無需重新標定儀表系數(shù)。應用范圍廣，蒸汽、氣體、液體的流量均可測量。廣元渦街流量計</p><div style="width:100%;text-align:

渦街流量計正確選型才能保證渦街流量計更好的使用。選用什么種類的渦街流量計應根據(jù)被測流體介質(zhì)的物理性質(zhì)和化學性質(zhì)來決定?使渦街流量計的通徑、流量范圍、襯里材料、電極材料和輸出電流等都能適應被測流體的性質(zhì)和流量測量的要求。 </p> <p> 1、精密功能檢查 </p> <p> 精度等級和功能根據(jù)測量要求和使用場合選擇儀表精度等級，做到經(jīng)濟合算。比如用于貿(mào)易結(jié)算、產(chǎn)品交接和能源計量的場合，應該選擇精度等級高些，如1.0級、0.5級，或者更高等級; </p> <p> 用于過程控制的場合，根據(jù)控制要求選擇不 </p> <p> 同精度等級;有些**是檢測一下過程流量，無需做精確控制和計量的場合，可以選擇精度等級稍低的，如1.5級、2.5級，甚至 </p> <p> 4.0級，這時可以選用價格低廉的插入式渦街流量計。 </p> <p> 2、可測量的介質(zhì) </p> <p> 測量介質(zhì)流速、儀表量程與口徑 </p> <p> 測量一般的介質(zhì)時，渦街流量計的滿度流量可以在測量介質(zhì)流速0.5—12m/s范圍內(nèi) 選用，范圍比較寬。選擇儀表規(guī)格(口徑)不一 </p> <p> 定與工藝管道相同，應視測量流量范圍是否在流速范圍內(nèi)確定，即當管道流速偏低，不能滿足流量儀表要求時或者在此流速下測量準 </p> <p> 確度不能保證時，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測量結(jié)果。 </p><p> 檢定周期為二年。 </p> <p> 渦街流量傳感器應用內(nèi)徑范圍為25-300mm（滿管式） </p> <p> 插入式渦街流量傳感器應用內(nèi)徑范圍為350-1200mm(插入式)。 </p> <p> 滿管式測量液體精度為1% </p> <p> 測量蒸汽和氣體精度為1.5% </p> <p> 插入式測量液體精度為2% </p> <p> 測量蒸汽和氣體精度為2.5% </p> <p> 被測介質(zhì)溫度為-20~150℃、-40~250℃、+100~350℃（*管式） </p> <p> 輸出信號為三線制電壓脈沖，三線制4-20mA、二線制4-20mA。 </p> <p> <br /> </p> <p> 功能 </p> <p> 表體中同時集成溫壓補償補償功能，可測量流體的標準體積流量或標準質(zhì)量流量。 </p> <p> 全智能化、數(shù)字化電路設(shè)計，可自動補償被測流體密度或標況體積計算。 </p> <p> 全新的數(shù)字濾波和修正功能使流量測量更加精細可靠。 </p> <p> 電池供電型無需外接電源既可連續(xù)工作兩年以上。 </p> <p> 全新點陣漢字液晶顯示，使用操作更方便。
