OPTIMASS 6400 C Coriolis mass flowmeter – Compact version with flange

The OPTIMASS 6400 is the standard high performance Coriolis mass flowmeter for the process industry. The twin bent tube meter offers superior performance and high accuracy in virtually any application: From process control in (petro)chemical applications to concentration measurements in the food and beverage industry to custody transfer filling and transport measurements in the oil and gas industry. Its high-end options also make the OPTIMASS 6400 the optimum device for cryogenic media like Liquefied Natural Gas (LNG) with temperatures down to -200°C / -328°F as well as applications involving high operating temperatures (up to 400°C / 752°F) or pressures (up to 200 barg / 2900 psig).

The OPTIMASS 6400 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 device enables continuous and uninterrupted measurement of mass and volume flow, density and temperature – even at difficult process conditions with 2-phase flow. The meter has various approvals for hazardous areas and is also suitable for use in Safety Instrumented Systems (SIL2/3). It comes with extensive diagnostic functions (NE 107) and various digital communication options.
