Flow Controllers & Meters


High Accuracy CODA Coriolis Mass Flow Controllers

High Accuracy CODA Controllers control true mass flow at ±0.2% of reading. These controllers provide additional benefit for systems with corrosives or those under extreme pressure.
  • Versatile control. Control mass flow even when 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.
