Overview
The OPTIMASS 7400 is a high-end Coriolis mass flowmeter for demanding process and custody transfer (CT) applications. It is the ideal solution when it comes to high accuracy measurement of gases and shear-sensitive or viscous liquids, slurries, very aggressive media or media with a low flow velocity. The meter features Entrained Gas Management (EGMTM) for liquid applications, providing reliable readings even in the event of gas entrainment of up to 100%. In this way, the Coriolis meter enables continuous and uninterrupted measurement of volume flow and mass, density and temperature – even at difficult process conditions with 2-phase flow.
The OPTIMASS 7400 is the only single straight tube mass flowmeter for use when custody transfer is required in the highest OIML accuracy class of 0.3. Together with the OPTIMASS 7010, it is also the only Coriolis meter with a single straight tube to be available in four sensor materials (titanium, stainless steel, Hastelloy® C, tantalum). Due to its sensor design, there is virtually no pressure loss and the flowmeter is self-draining and easy to clean, which makes it also the perfect choice for hygienic applications. The Coriolis device can also be used in hazardous areas. Like with all other KROHNE mass flowmeters there are no installation restrictions as the flowmeter is immune to crosstalk/line vibrations and can thus be installed in series or in parallel. The Coriolis mass flowmeter also provides enhanced diagnostics (NE 107) and comes with various digital communication options.
