西門子SIEMENS超聲波流量計(jì)7ML5034-2AA01

西門子管段式超聲波流量儀表是以“速度差法"為原理積極，測(cè)量圓管內(nèi)液體流量的儀表。它采用了的多脈沖技術(shù)綠色化發展、信號(hào)數(shù)字化技術(shù)及糾錯(cuò)技術(shù)供給，使流量儀表能適應(yīng)工業(yè)現(xiàn)場(chǎng)的環(huán)境，計(jì)量方便使用、經(jīng)濟(jì)分析、準(zhǔn)確。達(dá)到外不難發現，可廣泛應(yīng)用于石油合規意識、化工、冶金推動、電力協調機製、給排水等領(lǐng)域。
    西門子超聲波流量計(jì)是通過檢測(cè)流體流動(dòng)對(duì)超聲束(或超聲脈沖)的作用以測(cè)量流量的儀表有效性。
    原理
    根據(jù)對(duì)信號(hào)檢測(cè)的原理超聲流量計(jì)可分為傳播速度差法(直接時(shí)差法高質量發展、時(shí)差法、相位差法和頻差法)、波束偏移法攻堅克難、多普勒法機遇與挑戰、互相關(guān)法、空間濾法及噪聲法等相關。
    西門子超聲流量計(jì)和超聲波流量計(jì)樣取得明顯成效，因儀表流通通道未設(shè)置任何阻礙件，均屬*流量計(jì)影響力範圍，是適于流量測(cè)量困難問題的類流量計(jì)大力發展，特別在大口徑流量測(cè)量方面有較突出的優(yōu)點(diǎn)，它是發(fā)展迅速的類流量計(jì)之雙向互動。
    西門子超聲波流量計(jì)采用時(shí)差式測(cè)量原理：個(gè)探頭發(fā)射信號(hào)穿過管壁集成技術、介質(zhì)、另側(cè)管壁后綠色化，被另個(gè)探頭接收到設計，同時(shí)，二個(gè)探頭同樣發(fā)射信號(hào)被*個(gè)探頭接收到至關重要，由于受到介質(zhì)流速的影響，二者存在時(shí)間差Δt發展，根據(jù)推算可以得出流速V和時(shí)間差Δt之間的換算關(guān)系V=(C2/2L)×Δt改進措施，進(jìn)而可以得到流量值Q。
