U-Shaped Coriolis Flowmeters
Custody-transfer accuracy for high-capacity liquid and slurry pipelines — no external compensation required.
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 U-Shaped Coriolis for High-Capacity Liquid Measurement
When mass flow accuracy and fluid versatility are non-negotiable, the U-shaped Coriolis outperforms every indirect measurement technology across the same pipeline diameter range.
vs. Electromagnetic (Mag) Flowmeters:
- Measures mass flow directly — mag meters deliver volumetric flow only, requiring separate density input for mass conversion
- Works on hydrocarbons, oils, and non-conductive fluids — mag meters require a minimum fluid conductivity of ~5 µS/cm and cannot handle petroleum products
- Provides simultaneous density measurement — mag meters have no density output capability
- Unaffected by fluid conductivity variations — mag meter accuracy degrades when conductivity fluctuates or approaches the minimum threshold
- Full custody-transfer capability on non-aqueous media — mag meters are limited to conductive liquids only
vs. Turbine Flowmeters:
- No moving parts — turbine bearings wear progressively, causing measurement drift that is not self-evident without regular calibration pulls
- Handles viscous and abrasive fluids — high viscosity and entrained solids degrade turbine rotor performance and accelerate bearing wear
- Direct mass measurement — turbine meters are inherently volumetric; mass flow requires external density compensation
- Maintains accuracy at low flow — turbine meters suffer poor linearity at the low end of their range due to bearing friction effects
- No strainer required upstream — turbine meters require protection from particulates that Coriolis handles without additional filtration
vs. Differential Pressure Meters (Orifice, Venturi):
- No energy penalty — DP primary elements impose a permanent pressure loss; at high flow rates and large pipe sizes, this translates directly into pump and compressor operating cost
- Wide turndown without reconfiguration — a single orifice plate is designed for a fixed flow range; Coriolis handles the full operating envelope from startup to peak load
- Fewer installed components — eliminating DP transmitters, impulse lines, manifolds, and isolation valves reduces installed cost, leak risk, and maintenance points
- Accurate during density excursions — DP meters require re-calculation when fluid density shifts; Coriolis self-compensates continuously
- No straight-run requirements — DP elements need significant upstream and downstream straight pipe; Coriolis imposes no such constraint
