Krohne has unveiled the OPTIMASS 5400, a new Coriolis mass flowmeter for standard process applications with gases and liquids. The new device offers an optimised balance of performance, reliability, and cost efficiency
Applicable to a wide range of industries, including chemical processing, oil and gas, marine, food and beverage, and pharmaceuticals, the OPTIMASS 5400 addresses a variety of flow measurement tasks.
Typical applications include chemical and hydrocarbon flow control, utility measurement and fuel consumption monitoring. Its compact design makes the flowmeter well suited to mobile and skid-mounted systems, trucks, rail tankers, and portable process installations.
The OPTIMASS 5400 bridges the gap between entry-level and premium Coriolis meters, enabling direct measurement of mass flow, density and temperature, and providing valuable information on volume, concentration, and flow velocity.
The twin semi-bent tube flowmeter delivers high measurement performance across a wide operating range and can handle process temperatures up to +180°C and pressures up to 100 barg. The sensor housing provides typical burst-case pressure resistance up to 200 barg, adding an extra layer of protection and enhancing plant safety. The instrument also provides excellent mass flow and density measurement accuracy, with an optional mass flow accuracy of ±0.1% for flow rates above 10% of nominal flow.
The OPTIMASS 5400 is based on a modular production and supply system, enabling optimised processes across all production stages, reducing delivery time for the measuring device. Krohne aims to consistently deliver the standard configuration within two weeks. OPTIMASS 5400 also comes as a lightweight eco-design that requires fewer materials and components than previous generations of Coriolis flowmeters.
OPTIMASS 5400 includes Entrained Gas Management (EGM) technology, enabling stable measurement across a range of gas fractions and complex flow conditions. The technology also provides two-phase flow indication and supports monitoring gas volume fraction in liquids.
Featuring modular electronics, the flowmeter supports a range of communication protocols, including HART 7, Modbus, FOUNDATION Fieldbus, PROFIBUS-PA/DP, PROFINET, PROFINET over Ethernet-APL and EtherNet/IP. Three configurable 4…20mA outputs are available, complemented by integrated Bluetooth connectivity for wireless access.
Additionally, built-in OPTICHECK diagnostics continuously monitor instrument health and application conditions, providing detailed insights into the instrument and the process and supporting condition-based maintenance and process optimisation. The flowmeter also facilitates on-site verification without process interruption, reducing maintenance effort and increasing plant availability.
When used with the OPTICHECK Flow mobile app, the OPTIMASS 5400 enables commissioning, monitoring, and field verification to be conducted conveniently and securely via Bluetooth. OPTICHECK DTM is also available for remote access from the control room.
Available in both compact and remote versions, the OPTIMASS 5400 can serve as a flange-to-flange replacement for existing OPTIMASS 1000 series installations.
