歐洲*德國(guó)SIEMENS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。
SIEMENS超聲流量計(jì)和超聲波流量計(jì)一樣,,因儀表流通通道未設(shè)置任何阻礙件,,均屬*流量計(jì),是適于解決流量測(cè)量困難問(wèn)題的一類流量計(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)展迅速的一類流量計(jì)之一。
SIEMENS超聲波流量計(jì)采用時(shí)差式測(cè)量原理:一個(gè)探頭發(fā)射信號(hào)穿過(guò)管壁,、介質(zhì),、另一側(cè)管壁后,被另一個(gè)探頭接收到,,同時(shí),,第二個(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
