The Krohne OPTIMASS 6400 Series represents a premium line of Coriolis mass flow meters designed for precise measurement of liquids, gases, and slurries in demanding industrial environments. Leveraging dual-tube Coriolis technology, these flow meters deliver unmatched accuracy (±0.1% of mass flow) and stability, even under fluctuating process conditions. The series includes models 1400, 3400, 6400, and 7400, each tailored for specific applications—from hygienic processes in food production to high-pressure custody transfer in oil & gas. As original equipment, these flow meters ensure reliability and compliance with global standards.
