OPTIMASS 7400 Krohne

Coriolis mass flowmeter for advanced process applications

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 (EGM) 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.

• High accuracy (±0.1%), for viscous, aggressive or shear-sensitive media; maintains operation over a wide range of gas fractions and complex flow conditions
• CT: OIML R117, MI-005; API; hygienic certifications
• Flange: DN10…100 / ½…4", max. PN100 / ASME Cl 600; others
• 3 x 4…20 mA, HART^®7, Modbus, FF, Profibus-PA/DP, PROFINET
