Product Overview
Coriolis mass flow meters deliver the most accurate and direct measurement of mass flow available, making them essential in custody transfer, chemical dosing, and high‑value production processes. By measuring the Coriolis force in vibrating tubes, they simultaneously calculate mass flow, density, temperature, and derived variables such as concentration or standard volume. High‑performance designs—such as Micro Motion ELITE or KROHNE OPTIMASS—reach ±0.05% accuracy and operate from cryogenic to 400°C, with ratings up to ASME Class 1500. With advanced diagnostics like Smart Meter Verification, entrained‑gas management, and multi‑protocol digital communication, Coriolis meters ensure reliable, maintenance‑free measurement for complex fluids, gases, and slurries.
