Coriolis Mass Flowmeters

Coriolis Mass Flowmeters

Coriolis mass flowmeters determine flow by exciting one or more measuring tubes into vibration and evaluating the Coriolis forces that arise when fluid moves through the oscillating sensor. Because the measured effect is proportional to the mass moving in the tube, the primary output is direct mass flow. Modern implementations can simultaneously provide additional variables such as density and temperature, enabling richer process insight from a single installation.

The key advantage is measurement that supports tight control of material balance and composition without relying on separate compensations to convert volumetric flow into mass. Multi-variable data can improve batching, blending, and changeover verification, while also reducing the need for dedicated density instrumentation in many services. This measurement principle is applied broadly across industries, including custody transfer where traceable performance is often required.

Coriolis technology is used on an exceptionally wide range of fluids - from cleaning agents, solvents, fuels, crude oil, and vegetable oils to viscous food products such as sauces and condiments - along with gases and liquefied gases. Typical applications include high-accuracy dosing, additive injection, skid-based blending, loadout, and receipt metering where both flow and density trends are operationally valuable.

Selection and installation revolve around process compatibility and measurement stability: pressure class, temperature range, corrosion resistance, and (where applicable) hygienic or drainable construction. While straight-run requirements are generally modest compared with some volumetric meters, mechanical influences matter - mounting rigidity, external vibration, and severe pulsation or intermittent two-phase flow can all degrade signal quality if not addressed in the design.

Within Endress+Hauser’s portfolio, Coriolis solutions are represented by the Proline Promass family, including models such as Promass F 300 for general-purpose service and Promass U 500 for single-use measurement approaches in biotech contexts. Applied appropriately, Coriolis meters consolidate critical measurements at the point of flow and support consistent product quality and accountability across transfer and process operations.
