Innovative construction for better results
KROHNE has 3 decades of experience in bent self-draining tube designs. Furthermore the OPTIMASS 6400 uses proven, patented flow splitter technology that provides minimum pressure loss. The OPTIMASS 6400 is available in DN 08 to 100 (DN 150 to 250 pending) and in 3 different materials: 316L stainless steel, Hastelloy® C-22 and Duplex UNS31803.
Due to its superior design and latest, most advanced modern components, the OPTIMASS 6400 provides accurate measurements even in cryogenic and high temperature applications ranging from -200 to +400 °C / -328 to +752 °F and has high pressure capability up to 200 bar / 2900 psig.
So, whatever your requirements, you can be rest assured that your OPTIMASS 6400 meter has been made to the highest standards and that no compromises have been made on quality.
Superior performance for simple task completion
The MFC 400 mass flow signal converter is an electronics unit which is perfectly suited to all measuring tasks at the highest level of technology. The MFC 400 offers high performance with air entrainment, excellent zero stability and advanced density measurement. It is approved according to ATEX, IECEx, GOST and cFMus and has achieved other local approvals as well. It comes with a remote converter that reaches up to 20 m / 65.6 ft. The meter is approved for CT applications according to MID MI 005 and OIML R 117-1 for liquids different from water including LPG and according to MID Mi 002 for gases. A DNV GL marine approval is also available.

EGM™ (Entrained Gas Management)
The OPTIMASS 6400 synthetic drive control ensures continuous measurement even with high entrained gas conditions. The drive system can be optimised to the application to correct for less than ideal operating conditions.
On-site replacement
In the unlikely event that a fault occurs with the electronic system, the complete electronics cartridge can be conveniently replaced on-site. And thanks to redundant storage, the data is simply transferred from the housing backplane memory to the new signal converter. This way the process is only interrupted for a short period of time.
MFC 400 C
Compact installation on the sensor
MFC 400 F
Separate installation up to a max. of 20 m / 65.6 ft from the sensor
Seven measuring functions in one device –
And all of them perfectly under control
Up to seven measuring functions in a single device? The OPTIMASS 6400 makes it possible: mass flow rate, mass counter, density, temperature, volume flow rate, volume counter and concentration of fluids and gases. This “7 in 1” solution means low investment costs and minimal maintenance costs.
And so as not to lose the big picture amongst so many functions, the OPTIMASS 6400 is factory-fitted with an extensive diagnostics package: not only does the software monitor the flowmeter itself but also the process and the process conditions.
Learn more about the diagnostics package
Within the system, the software records the temperature of the medium, the density, concentration, speed and state of the respective medium. In this way, gas as well as solid inclusions can be identified.
When it comes to the process conditions the OPTIMASS 6400 diagnostic software does not miss a thing, every fraction of a second it sees changes; including temperature, an installation error, or changes in driver amplitude.
Plain sailing installation, commissioning and operating
User friendliness has many aspects when it comes to the OPTIMASS 6400: whether installation, commissioning, operation or communication – everything was designed to make things easy for the user in the truest sense of the word.
Learn more about:
Installation
The installation for example. Whether it’s horizontal, vertical or diagonal, the OPTIMASS 6400 can be integrated into virtually any system, regardless of the type of installation or external influences such as pipeline vibrations. Since there are no inlet and outlet runs, the compact design and minimal weight of the sensor are a huge plus during installation. Should pipe supports prove necessary in some cases, they can be attached on the pipeline wherever desired.
Commissioning
Or commissioning for instance. Once the OPTIMASS 6400 has been installed, the electronics automatically run a self-test. This covers 90 % of the parameters. Once installed, the OPTIMASS 6400 is ready for service immediately.
Operating
Operation is simple and convenient thanks to a user-friendly interface with 4 integrated optical/push buttons. This design is extremely practical. For example, the glass cover protecting the display from dirt and dust does not have to be removed during operation and configuration. The display and user interface are available in multiple languages, and the rotating, high contrast display always makes for optimal legibility.
The OPTIMASS 6400 uses the tried and tested HART®, FOUNDATION fieldbus™, Modbus and PROFIBUS® interfaces for communication. And configuration uses PACTware™ including the necessary DTM free of charge.
Intelligent modularity to suit needs and fulfil requirements
When it comes to selecting a flowmeter for your application, the OPTIMASS range covers all bases of all relevant industries around the globe. KROHNE offers superior straight and bent tube design mass flowmeters. From small to large. For 0.00015 to 2300 t/h flows. For custody transfer applications or problematic applications such as highly viscous media, non-homogeneous mixtures, media with solid content or gas inclusions.
