RHE 42

Ex de Field Mount

With its advanced digital signal processing capability and in conjunction with our sensors, the RHE 42 can achieve an ultimate mass flow measurement uncertainty of 0.05 %, making it ideal for both filling and bottling or any kind of high accuracy/reliability plant flow or density measurement. Connectivity includes a full suite of communications buses including Foundation Fieldbus and Modbus TCP/IP. The RHE 42 is a well specified transmitter relevant for large scale plant and project opportunities.

  • Measures Mass Flow, Volumetric Flow, Density and Temperature
  • Outputs 2 x Analog, 2 x Frequency/Pulse, 2 x Digital Status
  • Inputs 2 x Digital
  • PC USB / RHECom, RS 485 / Modbus RTU, Modbus TCP, Foundation Fieldbus and Profibus PA
  • Optional Backlit Color LCD
  • Installation in Hazardous Area
  • Rheonik Assurance Factor®
