CODA Coriolis Mass Flow Pump Controller

CODA Coriolis Mass Flow Pump Controllers easily integrate with your existing liquid or gas pump process and enable full automation without needing a separate PID controller. The controller can also be configured to command a valve for use with pressurized gas.

This precision controller reads mass flow in <40 ms and sends a digital signal to control the pump in <140 ms. Controllers are compatible with gasses and liquids up to 200 cP and flow rates up to 300 kg/h.

Specs, features, and customization options


Highest possible accuracy and responsiveness with custom ranging — included with every system.

CODA KF-Series performance
  • Full scale ranges: 40 g/h to 300 kg/h
  • Measures and controls mass or volumetric flow
  • Steady state control range: 5%–100% of full scale
  • Accuracy calibration, NIST-traceable (liquid): ±0.6% of reading or ±0.2 of full scale, whichever is greater
  • Repeatability: ±0.1% of full scale
  • Response time:
    40–10,000 g/h: <140 ms (T63), pump-dependent, user-adjustable
    30–300 kg/h: <200 ms (T63), pump-dependent, user-adjustable
  • Density accuracy ±5 kg/m3
CODA KF-Series operating conditions
  • Operating temperature: -35 to 70°C
  • Proof pressure: 1500 PSIA (103.4 barA); optional 4,000 PSIA (275.8 barA) for ≥100 g/h instruments
Device features and accessories
  • Adding your pump produces liquid flow in situations where you don’t have a pressurized source.
  • Measure and control true mass flow, even when fluid composition is changing or unknown.
  • Batching and dosing built-in: deliver a precise preset amount of fluid, then stop flowing.
  • Works with your pump (check with us for suitability).
  • Measures densities from 100 to 2,000 kg/m3
  • Insensitive to external vibrations to mitigate process disturbances.
  • With high accuracy option, you can mix at ultra-low flows.
  • FlowVision software (download)
