Coriolis liquid flow meters provide high accuracy measurement of liquid flows up to 300 kg/h. The ability to measure liquids independent of composition and aggressive properties makes these liquid flow meters the ideal choice in critical industries such as fuel cell, food & beverage, and semiconductor.

  • Composition independent. Coriolis liquid flow meters provide high-accuracy readings regardless of liquid composition, giving you an accurate flow measurement even when your fluid composition is changing or unknown.
  • High accuracy. With NIST-traceable accuracy to ±0.2% of reading and repeatability to ±0.05% of reading, Coriolis liquid meters ensure you can carefully monitor and respond to changing process conditions including changes in composition or temperature.
  • Robust material compatibility. Available with metal seals and Hastelloy, Coriolis mass flow instruments are compatible with a wide range of liquids including those with aggressive components.
  • Insensitivity to external vibration. Built with real-world environments in mind, our Coriolis instruments are able to withstand external vibrations (check out the video).
