RHE 46


Compact, cost effective and highly accurate. The RHE 46 offers the full range of features of the Rheonik 40 series, while being easy to install in a DIN rail. 
With its advanced digital signal processing, the RHE 46 can achieve an ultimate measurement uncertainty of 0.05% for mass flow, making it ideal for bottling or any type of highly accurate/reliable flow or density measurement in plants.

  • Cost effective DIN Rail mount
  • Multiparameter - measures Mass Flow, Volumetric Flow, Density and Temperature
  • Outputs: 1 x Analog, 2 x Frequency/Pulse/Status
  • Inputs: 1 x Digital
  • Interfaces: PC USB/RHECom, ProfiNet, EtherNet/IP, RS485/Modbus RTU, Modbus TCP
  • Rheonik Assurance Factor®
