OPTIMASS 6400 Flowmeter

Description

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.
