Alicat Scientific CODA KM-Series Coriolis Mass Flow Meters is used for high accuracy measurement under extreme operating conditions.

Alicat Scientific CODA KM General Description

CODA meters are compatible with a wide range of liquids and gases (including many corrosives), and maintain high accuracy for pressures up to 4000 PSIA and flow rates down to 40 g/h.

  • Versatile measurement. Measure mass flow even when the fluid composition is changing or unknown, with NIST-traceable accuracy to ±0.2% of reading and repeatability to ±0.05% of reading.
  • Robust material compatibility. Available with wetted materials that are compatible with a wide range of aggressive gases and liquids.
  • Insensitivity to external vibration. Inherent resistance to external vibrations mitigates environmental process disturbances.
