Triangle-Shaped Coriolis Flowmeter
Built for low-flow and small-diameter processes where measurement precision cannot be compromised
When your process involves precise ingredient dosing, high-value chemical injection, or small-batch blending, indirect flow measurement introduces unacceptable uncertainty. The triangle-tube Coriolis meter eliminates that uncertainty entirely — measuring mass flow directly from the Coriolis force acting on the fluid itself, independent of fluid properties, viscosity, or temperature shifts. Simultaneous density output makes it equally capable as an inline concentration or quality monitor.

Why Triangle-Tube Coriolis for Low-Flow Precision Measurement
vs. Positive Displacement Meters (Oval Gear, Rotary)
- Direct mass measurement — no density correction needed for custody accuracy
- No rotating elements — zero wear on precision-matched gear surfaces over time
- Handles aggressive, high-purity, and abrasive media without wetted mechanical parts
- Simultaneous density output — PD meters measure volume only
- No viscosity-dependent calibration shift across operating temperature changes
- Higher initial unit cost (offset by elimination of maintenance and recalibration intervals)
vs. Turbine / Micro-Turbine Flowmeters
- Immune to viscosity variation — turbine K-factor drifts with fluid viscosity changes
- No minimum Reynolds number requirement — accurate at any flow velocity
- No bearing wear or blade damage in abrasive or particle-laden service
- Direct mass output — turbine measures velocity and requires fluid density assumption
- Accurate from the very first pulse — no spin-up lag at low flow onset
vs. Magnetic Flowmeters (Small-Bore)
- Measures non-conductive fluids — Coriolis imposes no minimum conductivity requirement
- Valid for oils, hydrocarbons, solvents, and pure water where mag meters cannot operate
- Simultaneous mass, density, and temperature — mag meters output volumetric flow only
- Unaffected by empty-pipe conditions — no false readings on startup or drain-down
- No external grounding rings or cathodic protection required
