SIEMENS流量計現(xiàn)貨低價處理中 SIEMENS超聲流量計和超聲波流量計一樣,因儀表流通通道未設置任何阻礙件,均屬*流量計,是適于解決流量測量困難問題的一類流量計,特別在大口徑流量測量方面有較突出的優(yōu)點,它是發(fā)展迅速的一類流量計之一。
SIEMENS超聲波流量計采用時差式測量原理:一個探頭發(fā)射信號穿過管壁、介質(zhì)、另一側管壁后,被另一個探頭接收到,同時,第二個探頭同樣發(fā)射信號被*個探頭接收到,由于受到介質(zhì)流速的影響,二者存在時間差Δt,根據(jù)推算可以得出流速V和時間差Δt之間的換算關系V=(C2/2L)×Δt,進而可以得到流量值Q
SIEMENS超聲波流量計是一種非接觸式儀表,它既可以測量大管徑的介質(zhì)流量也可以用于不易接觸和觀察的介質(zhì)的測量。它的測量準確度很高,幾乎不受被測介質(zhì)的各種參數(shù)的干擾,尤其可以解決其它儀表不能的強腐蝕性、非導電性、放射性及易燃易爆介質(zhì)的流量測量問題。

SIEMENS超聲波流量計正確選型才能保證超聲波流量計更好的使用。選用什么種類的超聲波流量計應根據(jù)被測流體介質(zhì)的物理性質(zhì)和化學性質(zhì)來決定?使超聲波流量計的通徑、流量范圍、襯里材料、電極材料和輸出電流等?都能適應被測流體的性質(zhì)和流量測量的要求。
