2. Challenges in Chemical & Petrochemical Flow Measurement
The chemical industry presents some of the toughest measurement conditions:
- Corrosive and aggressive liquids
Acids, alkalis, bleach, solvents, and brine attack meter interiors.
- Highly viscous fluids
Resins, polymers, latex, aromatics require stable measurement solutions.
- Abrasive slurries
Chemical slurries cause wear and erosion.
- Hazardous/explosive environments
Petrochemical plants require flameproof or intrinsically safe meters.
- High temperature & pressure
Reactor feeding lines and distillation columns operate under extreme conditions.
- Changing conductivity
Electromagnetic meters require liquid conductivity above threshold.
- Clean-in-place (CIP) chemicals
Flow meters must tolerate strong cleaning agents.
To address these challenges, Saitechflow designs flow meters with specialized materials and safety certifications.
