Proline Promass A 200
科里奧利質(zhì)量流量計(jì)

真正的兩線制回路供電的流量計(jì)，用于極小流量的高精度測(cè)量。
一體式Promass A是在嚴(yán)苛工況下進(jìn)行連續(xù)過(guò)程控制的理想選擇。單測(cè)量管流量計(jì)帶獨(dú)一無(wú)二的自排空功能，能夠高精度測(cè)量極小流量的液體和氣體，也可以在高壓條件下測(cè)量。采用經(jīng)濟(jì)的兩線制回路供電技術(shù)和本安設(shè)計(jì)（Ex ia），即使在危險(xiǎn)區(qū)中使用Promass A 200也具有最高操作安全性。Heartbeat Technology心跳技術(shù)確保過(guò)程始終安全。
