  是差压、浮子和浮筒式物位计的可靠替代品。
  采用两线制技术，有效的降低布线成本，且易于实现与现有系统的集成
• 非接触式测量
  测量几乎不受介质特性影响
• 通过数文引导式菜单轻松进行现场操作.
• 通过Endress+Hauser的操作软件便于进行仪表调试、文件编制和故障诊断
• 频率范围采用K波段
• 支持HART 或PROFIBUS PA以及FF基金会现场总线协议
• 用于物位监测(MIN, MAX) ，符合 IEC 61508/IEC 61511-1标准的要求，通过了SIL 2 认证

应用领域

Micropilot M可用于对液体、浆料、淤泥和固料进行连续的非接触式物位测量。测量不受介质改变，温度变化，气压或蒸汽的影响。

 

FMR244不仅具有喇叭天线的优势，而且还具有极强的抗化学腐蚀性。80mm(3")喇叭天线还可以用于固体测量.
