Coriolis Mass
Flow Meters

All Rheonik meters have the unique Omega shaped flow tubes.
No other design offers such versatility and rangeability:

• Measurement of liquids and gas
• Flow rates from 0.001 kg/min. to 25000 kg/min.
• Diameters up to 12 inch / DN 300
• Pressure over 890 bar
• Temperature from -200°C to +400°C
• Available in EEx ia IIC - EEx de IIC (ATEX and CSA)
• Fiscal approval (OIML R117)
• Available in Stainless Steel, Hastelloy, Tantalum and others

The Advantages Summary

• No change of accuracy with changing pressures - active measurement
  section is half round and keeps its form at any pressure
• Active measurement section of Omega is de-coupled from process connections via mass bars - hence vibrations do not influence very
  much as with conventional CMFs
• Tensions from the process side cannot disturb active measurement section of Omega since de-coupled - straight tube is very vulnerable in this regard
• Mass bar and torsion rods (rods work as a spring) form an harmonically swinging system => great stability and little energy needed (therefore intrinsically safe)
• Mass bar - torsion rod system provides very big amplitudes, hence
  great signal to noise ratio. Even smallest rates can be measured reliably. Straight tubes have low signal to noise ratio
• Torsion swinger allows bigger wall thickness, hence higher-pressure ratings, increased safety, and high 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. No long face-to-face length as straight meters
• Separate transmitter for flexibility - easy to integrate into systems
