4 Criteria to choose your mass flow meter

Measurement accuracy and repeatability

Essential for custody transfer and precise chemical dosing where even minor deviations result in significant financial or quality losses.

Fluid properties and compatibility

Corrosive, viscous, or abrasive media require specific wetted materials like Hastelloy to ensure long-term sensor integrity and safety.

Turn-down ratio requirements

Defines the range over which the meter maintains accuracy, critical for processes with highly variable flow rate fluctuations.

Process temperature and pressure

Extreme operating conditions necessitate robust construction and thermal compensation to prevent measurement drift or catastrophic mechanical component failure.

Available technologies and advantages

Coriolis Mass Flow Technology
Utilizing inertia for direct mass measurement, these devices provide high accuracy across varying density and viscosity without requiring additional pressure or temperature compensation. High accuracy and multi-variable data outputs provide excellent process control, yet high capital expenditure and vibration sensitivity necessitate careful site evaluation.
Thermal Mass Flow Technology
Measuring heat dissipation from a heated sensor probe, these meters are optimized for gas applications and offer exceptional sensitivity at very low flow rates. No moving parts ensure reliability and low pressure drop saves energy, but clean gas requirements limit use in dirty or wet environments.

6 expert tips

Prioritize Coriolis technology for high-value custody transfer applications to ensure maximum financial precision and minimize billing disputes globally.
Verify the technical certification to ensure compliance with local building safety standards and long-term durability.
Evaluate total cost of ownership including maintenance intervals and calibration frequency rather than focusing solely on initial acquisition.
Select digital communication protocols like HART or EtherNetIP to enable seamless integration with existing industrial automation and control.
Inspect installation requirements regarding straight pipe runs to avoid measurement inaccuracies caused by turbulent flow or mounting constraints.
Ensure material traceability for all wetted parts to comply with strict industrial safety and quality management system standards.
