SIEMENS西門子超聲波流量計(jì)7ML1034-1AA112

西門子管段式超聲波流量?jī)x表是以“速度差法"為原理，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)、信號(hào)數(shù)字化技術(shù)及糾錯(cuò)技術(shù)，使流量?jī)x表能適應(yīng)工業(yè)現(xiàn)場(chǎng)的環(huán)境，計(jì)量方便、經(jīng)濟(jì)、準(zhǔn)確。達(dá)到外，可廣泛應(yīng)用于石油、化工、冶金、電力、給排水等領(lǐng)域。
西門子超聲波流量計(jì)是通過(guò)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。
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、時(shí)差法、相位差法和頻差法)、波束偏移法、多普勒法、互相關(guān)法、空間濾法及噪聲法等。
西門子超聲流量計(jì)和超聲波流量計(jì)樣，因儀表流通通道未設(shè)置任何阻礙件，均屬*流量計(jì)，是適于流量測(cè)量困難問(wèn)題的類流量計(jì)，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。
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(guò)管壁、介質(zhì)、另側(cè)管壁后，被另個(gè)探頭接收到，同時(shí)，二個(gè)探頭同樣發(fā)射信號(hào)被*個(gè)探頭接收到，由于受到介質(zhì)流速的影響，二者存在時(shí)間差Δt，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，進(jìn)而可以得到流量值Q。
