產(chǎn)品描述
使用基于數(shù)字的SITRANS FX330渦街流量計，將蒸汽，氣體和液體的測量水平提高到一個全新的水平。 該設(shè)備主要為輔助，供應(yīng)和能源系統(tǒng)中的應(yīng)用而設(shè)計，在過程工業(yè)中用途廣泛。 SITRANS FX330具有集成式熱量表，符合NAMUR NE107的狀態(tài)報警器以及廣泛的Ex認證等新功能，非常適合各種化工，電力以及石油和天然氣安裝。 渦街流量計產(chǎn)品程序包括兩種類型的流量計：法蘭式和三明治式。
•無磨損-具有抗腐蝕，耐壓和耐高溫的不銹鋼結(jié)構(gòu)
•可用于危險區(qū)域-符合IEC 61508第2版的SIL2認證
•節(jié)省空間的安裝-整體減小公稱直徑，實現(xiàn)經(jīng)濟安裝
•冗余數(shù)據(jù)管理-交換電子產(chǎn)品而不會丟失校準和配置數(shù)據(jù)
•高級能源管理-計算總熱量和凈熱量
