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),是適于解決流量測量困難問題的一類流量計(jì),特別在大口徑流量測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)差式測量原理:一個(gè)探頭發(fā)射信號穿過管壁、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.
西門子超聲波流量計(jì)由超聲波換能器、電子線路及流量顯示和累積系統(tǒng)三部分組成。超聲波發(fā)射換能器將電能轉(zhuǎn)換為超聲波能量,并將其發(fā)射到被測流體中,接收器接收到的超聲波信號,經(jīng)電子線路放大并轉(zhuǎn)換為代表流量的電信號供給顯示和積算儀表進(jìn)行顯示和積算。這樣就實(shí)現(xiàn)了流量的檢測和顯示。
西門子超聲波流量計(jì)常用壓電換能器。它利用壓電材料的壓電效應(yīng),采用適出的發(fā)射電路把電能加到發(fā)射換能器的壓電元件上,使其產(chǎn)生超聲波振勸。超聲波以某一角度射入流體中傳播,然后由接收換能器接收,并經(jīng)壓電元件變?yōu)殡娔埽员銠z測。發(fā)射換能器利用壓電元件的逆壓電效應(yīng),而接收換能器則是利用壓電效應(yīng)。
