Krohne Introduces Optimass 6400 Coriolis Mass Flow Meter

Oct. 16, 2015
Krohne flow meter features entrained gas management and signal converter with advanced device and process diagnostics.

Krohne, Inc. introduces the Optimass 6400, a twin bent tube Coriolis mass flow meter suitable for standard liquid and gas applications in the chemical and petrochemical, oil and gas, pharmaceutical, food and beverage, and energy and power industries. The Optimass 6400 is equipped with a new signal converter that features advanced device and process diagnostics, compliant to NAMUR NE 107. The Optimass 6400 is approved for custody transfers of liquids and gases, making it appropriate for process industries and specialist applications like LNG, CNG or supercritical gases in terminal or storage/bunkering, along with custody transfer applications.

The Optimass 6400 Coriolis mass flow meter features advanced entrained gas management (EGM), with no loss of measurement with gas entrainment up to 100% of volume, according to the company. The Optimass 6400 with EGM can reportedly follow and correct for varying amplitudes. EGM continues to present an actual measured reading, together with an indication or configurable alarm that improves processes by identifying transient gas entrainments.

Available in a range of sizes from DN 08 to 250, the Optimass 6400 is offered in stainless steel 316L, Hastelloy C22 and Duplex steel UNS S31803. Compliant to NAMUR standard installation lengths, the Optimass 6400 operates in high temperatures up to 752°F (400°C), as well as cryogenic applications down to -328°F (-200°C). It also handles pressures up to 200 bar (2900 psi).

The Optimass 6400 is the first Krohne mass flow meter to feature the MFC 400 signal converter. The MFC 400’s fast digital signal processing enables the EGM feature and dynamic density measurement, as well as enhanced diagnostic and status indications, according to Krohne.
