optimass 6400

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).

Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.
