The Advantages Summary
|
Patented OMEGA design is the basis for the most advanced coriolis meter available:
|
- 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 very vulnerable in this regard
- Massbar and Torsion Rods (rods work as a spring) form an harmonically swinging system => great stability and little energy needed (therefore intrinsically safe)
- Massbar - Torison 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 affect 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
- Extreme applications
