High-performance meter for process industry.

Product Announcement from KROHNE Group

 High-performance meter for process industry.-Image

he NEW standard, high-performance meter for the process industry.

  • Advanced Entrained Gas Management (EGM): no loss of measurement with up to 100% gas entrainment
  • Cryogenic and high temperature applications from -200°C to +400°C / -328°F to 752°F
  • Highest accuracy for mass flow and density (pressure independent)

The OPTIMASS 6400 is a combination of KROHNE’s OPTIMASS 6000 twin bent tube Coriolis mass flow sensor and the latest state-of-the art MFC 400 digital electronics. It has been designed to meet standard liquid and gas applications in a wide range of industries and is available in sizes from DN08 to DN250 and in 3 materials: 316L stainless steel, Hastelloy® and Duplex UNS31803.

Due to its superior design, the OPTIMASS 6400 provides accurate measurements even in cryogenic and high temperature applications and has high pressure capability up to 200 bar/2900 psi. It also features advanced Entrained Gas Management (EGM) which allows the meter to identify and correct for varying amplitudes from 0 – 100% gas entrainments, whilst ensuring continuous measurement and of course indicating to the user that entrainments have been detected.
