The Optimass 6400 is said to be the first Coriolis mass flowmeter in the world to feature advanced entrained gas management (EGM), with no loss of measurement with gas entrainment up to 100 vol.%. Unlike other mass flowmeters, 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 and correct for the varying amplitudes. EGM continues to present an actual measured reading, together with an indication or configurable alarm that improves processes by identifying transient gas entrainments. The flowmeter is equipped with a new signal converter that features advanced device and process diagnostics, compliant to Namur recommendation NE 107. It is available in a range of sizes from DN 08 to 250, and is offered in stainless steel 316L, Hastelloy C22 and Duplex steel UNS S31803. The Optimass 6400 operates in temperatures from –200 to 400°C, and handles pressures up to 200 bars. — Krohne, Inc., Peabody, Mass.
