Rheonik Coriolis Flow Meter

Rheonik Messgeräte GmbH has more than twenty years of experience in the field of Coriolis Mass Flow meter design and development. Beginning in 1984, Karl Küppers began the design of a mass flow meter based upon the Coriolis effect that later became the patented Omega tube Coriolis Mass Flow meter manufactured by Rheonik today. 

After the exhaustive testing of many different designs, the Omega tube meter with torsion rods and mass bars was granted a patent based upon its unique operation and construction feature. Compared to other meter designs, the Rheonik Omega tube design offers outstanding performance and mechanical reliability. 

Rheonik was founded in 1986 by Mr. Küp
pers to commercially produce the Rheonik Mass Flowmeter range. Based initially in the town of Maisach near Munich, the company grew quickly due to the widespread  success of the Rheonik design in the field. 

To accommodate in creased demand, Rheonik Messgeräte GmbH relocated to a modern facility in Odelzhausen with increased production and office space.Today, Rheonik manufactures the largest range of Coriolis mass flow meters in the world for customers in more than 30 countries. With more than twenty years experience in the field, Rheonik Messgeräte GmbH is one of the world leaders of Coriolis Mass Flowmeter development and manufacture.

All  Rheonik coriolis mass flow meters are based on a patented Omega tube design with increased signal-to-noise ratio, for excellent performance and reliability. The combination of a patented torsion rod swinger with the Omega shape and support bars results in high accuracy measurement independent of pressure, even at very low flow velocities.

RHM coriolis flow sensors offer direct mass flow rate for liquids, sludge, and gases, all with high accuracies. These sensors are extremely resistant to gas bubbles entrained in the process stream, and are unaffected by viscosity, density, extreme temperatures, and pressure changes.
There's a Rheonik RHM coriolis mass flowmeter for nearly any flow application range:

Our Technology 
The typical Omega shaped Rheonik Coriolis mass flowmeter. All Rheonik meters are principally based on the design shown beside. No other design offers this degree of versatility and rangeability:

  • Measurement of liquid and gaseous fluids 
  • Flow rates from 0.002 to 30,000 kg/min (0.004 to 66,000 lbs/min) 
  • Diameters up to 12 inch / DN 300
  •  Pressure over 1,000 bar (14,500 psi) 
  • Temperature from -196°C to +395°C (-320°F to +743°F) 
  • Hazardous area certified versions available (ATEX, CSA etc.) 
  • Available in stainless steel, Alloy C22, Duplex, Tantalum and others

The Advantages Summary

Omega design is the basis for one of the most advanced Coriolis flow meters available:
  • No change of accuracy with changing pressures - active measurement section is half round and maintains its exact shape at any pressure
  • Active measurement section of the Omega is de-coupled from process connections via mass bars. Vibrations have less influence on measurement than with conventional Coriolis meters
  • Tensions from the process side cannot disturb active measurement section of Omega since it is de-coupled (straight tube shaped meters are very vulnerable in this regard)
  • Mass bar and torsion rods (rods work as a spring) form a harmonically oscillating system, resulting in great stability and little energy needed (therefore intrinsically safe)
  • Mass bar - torsion rod system provides very big amplitudes, hence excellent signal to noise ratio. Even smallest rates can be measured reliably.
  • Straight tubes have low signal to noise ratio
  • Torsion oscillator allows bigger wall thickness, hence higher pressure ratings, increased safety, and extreme temperature possible
  • Torsion movement instead of bending creates less stress in tubes - longer life time
  • Torsion movement is less affected by pipe vibrations since the vibrations are horizontal or vertical. Operational movement (torsion) is not in the same plane as the vibration movements - less cross talk
  • Compact form. Shorter face-to-face length than straight tube shaped meters
  • Separate transmitter for flexibility - easy to integrate into systems
  • Extreme applications
  • Sensor models rated over 1,000 bar are available
  • Temperatures from -196°C to +395°C
  • Highest accuracy under real-life conditions
  • Units available for fiscal duties
  • Low energy usage
  • EEx ia IIC sensors available (ATEX and CSA)
  • Flexible configuration
  • Diameters from ½" to 12"
  • Wetted parts materials available: stainless steel, Alloy C22, (Super) Duplex, Tantalum and others
