CODA KM–Series: Coriolis Mass Flow Meters

Alicat CODA KM-Series Coriolis mass flow meters are used for high-accuracy, precision measurement of a variety of fluids in applications including fuel cell testing & regulation, liquid dosing, and semiconductor.

  • Composition independence. Coriolis technology provides high-accuracy readings even when fluid composition is changing or unknown.
  • High accuracy. NIST-traceable accuracy to ±0.2% of reading and repeatability to ±0.05% of reading for tight, reliable process measurements.
  • Robust material compatibility. Available with wetted materials that are compatible with a wide range of aggressive fluids.
  • Insensitivity to external vibration. Inherent resistance to external vibrations mitigates environmental process disturbances.
