Coriolis & Vortex Flow Meters – mass and volumetric flow for liquids, gases & steam
Coriolis and Vortex flow meters cover a wide spectrum of process applications: Coriolis measures mass flow directly (plus density/temperature) with top accuracy, while Vortex robustly measures volumetric or mass flow of liquids, gases and especially steam with minimal maintenance.
Features (model-dependent): bidirectional measurement, integrated totalizers, I/O & communications (4–20 mA/HART, pulse, relay, Modbus/RS-485, Profibus/Profinet, EtherNet/IP, IO-Link), ATEX/IECEx, SIL, hygienic design, and energy/heat functions.
ICS Schneider Messtechnik supports principle selection, sizing (DN, Re/Strouhal, pressure/temperature), calibration (ISO/DAkkS) and integration into PLC/SCADA/IIoT.
FAQ on Coriolis & Vortex Flow Meters
Answers on working principle, accuracy, media, installation, compensation, energy use, calibration and digitalization.
How do Coriolis and Vortex differ?
| Criterion | Coriolis | Vortex |
|---|---|---|
| Measured variable | Mass flow directly + density/temperature | Volumetric flow (via vortex frequency); with T/p → mass flow |
| Media | Liquids & gases (clean/mixed) | Liquids, gases & steam (strong suit) |
| Accuracy | Very high (to ~±0.1% of rate) | Good (typically ±0.75…1.5% of rate) |
| Pressure loss | Medium (internal tubes) | Low to medium (bluff body) |
| Straight-run | Short | Longer (e.g., 15D/5D) |
| Sensitivities | Gas entrainment, vibration | Reynolds range, pulsation |
How does a Coriolis meter work?
One or two measuring tubes are vibrated. Flowing mass creates a phase shift (Coriolis force) between inlet and outlet proportional to mass flow. The tube’s resonance gives density; temperature is also measured.
How does a Vortex meter work?
Downstream of a bluff body, Kármán vortex streets form. Their frequency is proportional to velocity via the Strouhal number → volumetric flow. With pressure/temperature compensation you get mass flow (e.g., for steam).
What accuracy is realistic?
Coriolis: to ~±0.1% of rate (liquids), higher for gases; density to ~±0.001…0.002 g/cm³. Vortex: ~±0.75…1.5% of rate; with good installation and compensation very stable in practice.
Which media suit which principle?
- Coriolis: dosing/batching, mixtures, viscous or non-conductive media, custody-type tasks, density/concentration measurement.
- Vortex: steam (saturated/superheated), compressed air/process gases, water/broad ranges, energy metering.
How do I choose the nominal size (DN)?
Coriolis: based on acceptable Δp, viscosity and flow range; smaller DN increases resolution/signal. Vortex: ensure Reynolds number within spec and target pipe velocity; too low v → unstable signal.
What straight-run lengths are required?
Coriolis usually need short calming (e.g., 5D/3D). Vortex typically 15D upstream and 5D downstream; after strong disturbances consider a flow conditioner.
How do gas bubbles or two-phase flow affect results?
Coriolis: gas entrainment can dampen vibration → errors; use degassing, back pressure and proper process control. Vortex: two-phase creates noise—filter signals, adjust orientation, remove condensate.
Can Vortex measure steam energy?
Yes. With pressure and temperature compensation Vortex gives mass flow; combined with enthalpy tables you get steam energy (kWh/ton/h) for energy management.
Does Coriolis provide extra quality parameters?
Yes—density (→ concentration/Brix/API), temperature and sometimes viscosity trends. Ideal for mixing/dosing and recipe control.
What pressure/temperature limits apply?
Material/rating dependent: Coriolis commonly PN40…PN100+, temperatures >200 °C; Vortex versions are available for high p/T steam. Always check the datasheet.
What materials and connections are common?
316L/1.4404, 1.4571, and for corrosives Hastelloy® etc. Connections: flange (PN/ANSI), thread (G/NPT), clamp/hygienic. PED/ATEX/SIL options available.
Which signals & protocols are available?
4–20 mA/HART, pulse/frequency, relay, Modbus/RS-485, Profibus/Profinet, EtherNet/IP, IO-Link. Totalizers for forward/reverse; diagnostics such as signal quality, density, warnings.
What are typical accuracy pitfalls?
- Coriolis: missing zeroing, gas bubbles, strong pipe vibration, mechanical stress → decouple, zero correctly, avoid gas.
- Vortex: too low Re, heavy pulsation, too little straight-run → check DN/installation, use dampers/conditioners.
How is calibration performed?
Coriolis: factory/DAkkS mass calibration; density trim with standards. Vortex: volumetric/mass calibration, adjust K-factor/Strouhal constant; document traceability.
How do I integrate into energy management?
Vortex + T/p → steam mass/energy; Coriolis → fuel/media mass with ΔT for heat balances. Connect to SCADA/EMS/cloud via fieldbus/Ethernet with time/cost-center tagging.
What maintenance is required?
Both are low-maintenance (no moving parts). Regularly check process conditions, filtration/degassing, tightness, and plan calibration intervals per QA.
What mounting orientations are recommended?
Horizontal preferred. For Vortex steam: follow flow arrow, drain condensate, avoid “traps”, keep the run flooded. For Coriolis: stress-free mounting, straight runs before/after, vibration isolation.
Is bidirectional measurement possible?
Yes—both principles can measure forward/reverse. Configure electronics/totalizers accordingly and set direction switch thresholds.
How to handle large turndown requirements?
Coriolis supports wide turndown with good resolution; Vortex offers broad ranges but needs a minimum Re. For very low flows consider downsizing DN or a different principle.
Do you support selection, sizing & commissioning?
Yes. We compare Coriolis vs. Vortex for your media/pressure/temperature, size DN/straight runs, provide calibration certificates and integrate into PLC/SCADA/IIoT—including energy reporting.
