  • Easy installation
    • No straight both for upstream and downstream is required for process installation. No utility supply is needed.
  • Cost effectiveness
    • The pure mechanical construction offers most cost effective flowmeasurement.
  • Direct observation of measuring fluid
    • In addition to flow rate measurement, the measurement fluids are directly observed for better process fluid quality control.
  • Wide material selection
    • Besides the standard metallic material, resins and/or lining materials are available for corrosive fluids.
