KROHNE are pleased to announce their latest twin bent tube meter; the OPTIMASS 6000 series complete with MFC400 signal converter. It is ideal for liquid and gas applications in the chemical, petrochemical, oil & gas, pharmaceutical, food, beverage and power industries.  This powerful combination keeps KROHNE at the cutting edge of measurement technology and the OPTIMASS 6400 further strengthens the globally renowned OPTIMASS range of straight and bent tube Coriolis mass flowmeters that can offer a solution to virtually any application.

Compliant to NAMUR standard installation lengths the OPTIMASS 6400 is available in sizes DN 08 to DN 250 providing accurate measurement, even in cryogenic and high temperature applications ranging from -200 to +400°C /-328 to 752°F.  Furthermore, the OPTIMASS 6400 will operate in high pressure environments up to 200 bar (2900 psi)

The OPTIMASS 6400 is the world’s first Coriolis mass flowmeter to feature advanced Entrained Gas Management (EGMTM). 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. This indication can be very helpful to improve processes by identifying transient gas entrainments.

The unique feature of EGM and custody transfer approvals for both liquids (OIML R-117-1 / MI005) and gases (OIML – R137 / MI002), make the OPTIMASS 6400 suitable for process industries and specialist applications such as LNG, CNG or supercritical gases in terminal or storage/bunkering, along with custody transfer applications. The OPTIMASS 6400 is available in stainless steel 316L, Hastelloy® C22 and Duplex UNS31803.

In addition to the high technical specification, the OPTIMASS 6400 has the flexibility to achieve seven measuring functions: mass flow rate, mass counter, density, temperature, volume flow rate, volume counter and concentration of fluids including alcohol concentration.

Set up and operation of the OPTIMASS 6400 is simple and convenient thanks to a user-friendly interface, multi-lingual high contrast rotating display and 4 integrated optical/push buttons.  The tried and tested HART®, FOUNDATION fieldbus™ and PROFIBUS® interfaces are used for communication. Configuration uses PACTware™, including the necessary DTM free of charge.

Approved according to ATEX, IECEx, GOST and cFMus, the New MFC 400 mass flow signal converter is perfectly suited to all measuring tasks at the highest level of technology offering excellent zero stability and advanced density measurement.
