Rheonik RHE 42 Ex de Field Mount Coriolis Mass Flow Transmitter

ABLE Instruments are Rheonik’s Exclusive Representative for Sales and Service in the UK and Ireland, including the RHE 42 Ex de Field Mount Coriolis Mass Flow Transmitter. The RHE42 multifunction Coriolis mass flow transmitter from Rheonik provides reliable and accurate measurement in a wide variety of applications. Coupled with a Rheonik RHM flow sensor, the fully digital front end of the transmitter is tolerant to flow regimes not usually conducive to Coriolis meter applications (i.e., those with high pulsation/vibration/aeration). The housing is suitable for installation in a great many environments and includes a wide variety of hazardous area certifications and approvals.

The transmitter is available with or without local user display and interface. License free RHECOMPro software is downloadable from the web to allow remote communication with the transmitter for in-depth setup and configuration. Full local setup and operation is available “through glass” on units with a local display and user interface. Firmware features include, amongst others, batch control, partially filled/aerated pipe management, ultra-fast (millisecond) precision filling measurement, and net oil/API corrected volume/density reporting.


  • 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

Meters are equipped with Assurance View and Assurance Factor advanced diagnostics providing a clear insight into the operating condition of the meter and its performance. Assurance Factor can be linked to the large character colour LCD display (when fitted) to provide clear and visible signaling of measurement condition to operators and technicians nearby. The Rheonik RHE42 simultaneously measures mass flow, volumetric flow, density and temperature. Totalisers are included for forward, reverse and net accumulation of both mass and volume.

A wide range RHM flow sensors are available from ¼” to 14” line size for use with the RHE42 Coriolis Mass Flow Transmitter. With capabilities such as 20,000psi pressure ratings, exotic materials, customisable connection types/sizes and temperature ratings up to 400°C, the Rheonik Coriolis meter range covers more applications than any other Coriolis brand available on the market.
