Features

  • Bi-directional flow measurement of liquids and gases.
  • Cost-effective: no pipe work, no process shut down, maintenance-free.
  • Zero-point stable and drift-free - carefully matched and temperature compensated transducers (fully ANSI / ASME compliant).
  • Retrofittable - no pipe modification required, no process shutdowns.
  • Maintenance-free - free of wear and tear and abrasion, not prone to clogging or corrosion, no fugitive emissions.
  • High tolerance to entrained solids and gas wetness.
  • Independent of pipe size, material, operating pressure, and gas composition.
  • Flexible configurable outputs.
  • Advanced Meter Verification.
