KROHNE launches the OPTIMASS 6400: new twin bent tube Coriolis mass flowmeter for liquid and gas applications

The following are excerpts from a KROHNE press release.


·        New twin bent tube Coriolis mass flowmeter for liquid and gas applications

·        Advanced Entrained Gas Management (EGM): no loss of measurement with gas entrainment up to 100%

·        For high temperatures +400°C / 752°F down to cryogenic applications -200°C / -328°F

·        New signal converter with advanced device and process diagnostics, compliant to NAMUR NE 107

·        Liquid and gas custody transfer approval

Duisburg , June 14, 2012:  At Achema 2012, KROHNE introduces the new OPTIMASS 6400. Enhancing KROHNE’s OPTIMASS portfolio of Coriolis mass flowmeters, the OPTIMASS 6400 is an all-new twin bent tube Coriolis mass flowmeter to meet standard liquid and gas applications in the chemical and petrochemical, oil & gas, pharmaceutical, food & beverage, energy & power industries.

The OPTIMASS 6400 is the world’s first Coriolis mass flowmeter to feature advanced Entrained Gas Management (EGM). In the past, gas entrainments in liquid media presented a huge challenge for mass flowmeters because the relative movement between gas and fluid dampens the amplitude of the measuring tube. This dampening leads to inconsistent sensor amplitudes, which interfere with the electronics’ capability to determine the actual resonant frequency. While other mass flowmeters simply "freeze" their last stable reading to cover this "loss of measurement", the OPTIMASS 6400 with EGM is able to follow and correct for the varying amplitudes. This is achieved for entrained gas up to 100% of volume and continues to present an actual measured reading, together with an indication or configurable alarm for the user.

The entire press release will also appear in our upcoming Market Barometer.
