Why Choose Coriolis Mass Flow Meters?
Coriolis mass flow meters measure mass flow directly rather than inferring it from volumetric flow, pressure or temperature. This provides highly accurate, repeatable measurement across a wide range of process conditions, making them well suited to critical applications where precision is essential.
- Direct mass flow measurement: No need for external compensation for temperature or pressure changes
- High accuracy and repeatability: Suitable for batching, dosing and fiscal measurement
- Density and temperature output: Enables additional process monitoring and control
- No straight-run requirements: Performance is not significantly affected by upstream flow disturbances
- Wide turndown capability: Reliable measurement across varying flow rates
When Coriolis is a Strong Fit
Coriolis technology is typically selected where process accuracy, fluid variability or measurement reliability cannot be compromised. It is widely used where mass flow and density provide a more meaningful measurement than volumetric flow alone.
- Custody transfer and fiscal measurement: Certified measurement for commercial transactions
- Chemical and process industries: Handling of corrosive, viscous or variable-property fluids
- Food and pharmaceutical production: Hygienic batching, dosing and process control
- Oil & gas and energy: High-value fluids and demanding process environments
- Density-based process control: Concentration, blending and quality monitoring
Key Considerations Before Specifying
While Coriolis mass flow meters offer significant advantages, correct specification depends on understanding process conditions and application requirements.
- Process conditions: Pressure, temperature and fluid properties must be reviewed for suitability
- Entrained gas: High levels of gas within liquids can affect measurement stability
- Line size and installation: Larger pipe sizes may influence technology selection and cost
- Application objectives: Accuracy, control requirements and compliance considerations should guide selection
Featured Strength: High-Pressure and Hydrogen Measurement
In high-pressure and hydrogen applications, Coriolis mass flow meters must deliver both measurement accuracy and mechanical integrity under extreme process conditions. These environments place significant demands on sensor design, material strength and long-term stability.
Able supports these applications through its partnership with Rheonik, whose Coriolis meters are engineered specifically for high-pressure service. Their patented Omega tube design allows increased tube wall thickness while maintaining measurement performance, enabling operation at pressures exceeding 1,000 bar.
In addition to pressure capability, this design provides strong resistance to vibration and mechanical stress, helping maintain measurement stability and accuracy in demanding installation environments. This makes Rheonik Coriolis meters particularly well suited to hydrogen refuelling, industrial gas processes and other high-pressure applications where conventional designs may be more susceptible to instability.
