KROHNE OPTIMASS 6400 Coriolis mass flowmeter, DN10–300, ±0.05%, −200…+400 °C

The KROHNE OPTIMASS 6400 is a Coriolis mass flowmeter with a dual bent tube for demanding process applications and custody transfer. One device provides mass flow, density, volume flow, temperature and concentration of liquids and gases.

The Entrained Gas Management (EGM) function maintains measurement with gas entrainment and difficult flow conditions. Mass flow accuracy down to ±0.05% (option), medium temperature −200…+400 °C, pressure up to 200 bar, flanges DN10…300 up to PN 160 / ASME Class 1500. In-situ verification with OPTICHECK, diagnostics per NAMUR NE 107.
