产品描述
使用基于数字的SITRANS FX330涡街流量计，将蒸汽，气体和液体的测量水平提高到一个全新的水平。 该设备主要为辅助，供应和能源系统中的应用而设计，在过程工业中用途广泛。 SITRANS FX330具有集成式热量表，符合NAMUR NE107的状态报警器以及广泛的Ex认证等新功能，非常适合各种化工，电力以及石油和天然气安装。 涡街流量计产品程序包括两种类型的流量计：法兰式和三明治式。
•无磨损-具有抗腐蚀，耐压和耐高温的不锈钢结构
•可用于危险区域-符合IEC 61508第2版的SIL2认证
•节省空间的安装-整体减小公称直径，实现经济安装
•冗余数据管理-交换电子产品而不会丢失校准和配置数据
•高级能源管理-计算总热量和净热量
应用示例：化学，电力以及油气设
