The Optimass 6400 has been approved for custody transfers of both liquids and gases

Krohne, Inc has begun manufacturing the Optimass 6400 twin bent tube Coriolis mass flow meter at its newly opened flow and level instrument manufacturing and calibration facility located in Beverly, Massachusetts, USA. The Optimass 6400 is suited to standard liquid and gas applications in the chemical and petrochemical, oil and gas, pharmaceutical, food and beverage, and energy and power industries. It is equipped with a new signal converter that features advanced device and process diagnostics, compliant to NAMUR NE 107. The flow meter has been approved for custody transfers of both liquids and gases, making it suitable for process industries and specialist applications such as LNG, CNG or supercritical gases in terminal or storage/bunkering. The Optimass 6400 is claimed to be the first Coriolis mass flow meter to feature advanced entrained gas management (EGM), with no loss of measurement with gas entrainment up to 100 per cent of volume. Unlike other mass flow meters, where relative movement between gas and fluid dampens the amplitude of the measuring tube and interferes with the electronics’ capability to determine the actual resonant frequency, the Optimass 6400 with EGM can follow the varying fluid conditions and adapt the tube driver oscillations accordingly. EGM continues to present an actual measured reading, together with an indication or configurable alarm that improves processes by identifying transient gas entrainments. Sizes range from ½" to 1", and the Optimass 6400 is offered in stainless steel 316L, Hastelloy ® C22 and duplex steel UNS S31803. Compliant to NAMUR standard installation lengths, the Optimass 6400 operates in high temperatures up to 400°C (752°F), as well as cryogenic applications down to -200°C (-328°F). It also handles pressures up to 2,900 psi (200 bars).
