Coriolis Mass Flowmeters

Coriolis flow measurement: Simultaneous measurement of mass flow, density, temperature and viscosity.

Coriolis Mass Flowmeters

Endress+Hauser’s Coriolis mass flowmeters measure mass flow directly and simultaneously deliver density, temperature, and, in select versions, viscosity. The Coriolis principle is independent of fluid properties and flow profile, needs no inlet/outlet runs, and achieves typical ±0.1% o.r. accuracy with optional ±0.05% (PremiumCal). These multivariable meters provide a single source of truth for flow, density, and concentration, improving control and product quality.

The portfolio spans universal and specialist duties under the Proline Promass banner. Promass F is the all‑rounder; Promass Q is optimized for liquids with entrained gas and is favored for custody transfer; and four‑tube Promass X delivers the highest capacity at 0.05% accuracy. Single‑tube Promass A addresses ultra‑low flows. Complementary lines include Cubemass for the smallest flows on skids/test rigs, Dosimass with integrated batching, and CNGmass/LPGmass/LNGmass tailored for refueling and distribution (incl. LNG at −196 °C).

Transmitters scale with need: Proline 100/200/300/500 cover ultra‑compact, genuine loop‑powered two‑wire, compact four‑wire, and remote‑mount use. Heartbeat Technology enables online diagnostics and proof‑testable verification. A built‑in web server/WLAN and a broad protocol set, HART, FOUNDATION Fieldbus, PROFIBUS, Modbus RS‑485, EtherNet/IP, PROFINET, plus Ethernet‑APL options, simplify commissioning and integration.

Typical applications include precision batching/blending, skid dosing, concentration control (by density), and loading/unloading or custody transfer in chemical and hydrocarbon logistics. In mobility and energy, CNGmass/LPGmass/LNGmass serve high‑pressure and cryogenic dispensers; for sticky or multiphase liquids, Promass Q maintains accuracy with entrained gas. Coriolis meters are used across life sciences, food & beverage, oil & gas/marine, power, and MMM, delivering flow with minimal installation constraints.
