Rheonik RHM 30 Medium Coriolis Flow Meter

  • Robust torsion oscillator design.
  • Has a measuring range of between 7.5kg/min to 750kg/min.
  • Highly accurate with mass flow uncertainty being 0.15%.

Temperature and pressure ranges

The RHM30 from Rheonik is a precise Coriolis flow meter that can be used in a variety of mass flow applications. The high pressure ratings of up to 798 bar and vast fluid temperature range of -196°C to 350°C mean it can be used in extreme or routine applications.

Typical applications

Common applications for the RHM30 include Plant balance, high temperature liquids and viscous fluids.


With a large measuring range of between 7.5kg/min and 750 kg/min, consistent measurements are delivered within the working range. Mass flow uncertainty is low at 0.15% with repeatability even lower at less than 0.05% of reading.


The RHM30 has been approved for use in hazardous zones and has been given ATEX/IECEx approval for use in Zone 0, 1, 2. North American approvals have also given the RHM30 approval for Class I, Div.1 and Groups ABCD.


Sensor enclosures as standard are produced using stainless steel. 316 stainless steel is an optional material for the enclosure. The enclosures are protection class IP65 however they can be the upgraded option of IP66/NEMA 4X.


  • High pressure rating of 798 bar with a high fluid temperature rating of -196°C and 350°C.
