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 and thus maintains operation even with entrained gas of up to 100%. The meter has various approvals for hazardous areas and is also suitable for use in Safety Instrumented Systems (SIL 2/3). It comes with extensive diagnostic functions (NE 107) and various digital communication options. Via the OPTICHECK Flow Mobile app all device settings can be managed on-site via a secure Bluetooth® connection. In this way, a variety of commissioning tasks, e.g. zero calibration or configuration of diagnostics, can be done wirelessly.
