SIEMENS流量計(jì)現(xiàn)貨低價(jià)處理中 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(lèi)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(lèi)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
SIEMENS超聲波流量計(jì)是一種非接觸式儀表,它既可以測(cè)量大管徑的介質(zhì)流量也可以用于不易接觸和觀察的介質(zhì)的測(cè)量。它的測(cè)量準(zhǔn)確度很高,幾乎不受被測(cè)介質(zhì)的各種參數(shù)的干擾,尤其可以解決其它儀表不能的強(qiáng)腐蝕性、非導(dǎo)電性、放射性及易燃易爆介質(zhì)的流量測(cè)量問(wèn)題。
