Krohne Inc. has introduced the Optimass 2000, a large-diameter Coriolis mass flowmeter for accurate and repeatable bulk measurement in the oil industry. It uses the twin-straight-tube design of the Optimass 1000, and is available in three sizes: 4in, 6in and 10in. The meter’s wetted parts are constructed of NACE-compliant duplex stainless steel (ANS 31803), and it is available with flange ratings up to 1500lb, in flange sizes from 4in to 12in. The meter is CRN approved and can handle process pressures to 2200psig with a stainless steel outer cylinder that can handle burst pressures over 1500psi. Flowrates from 250 to 4400lb/min can be handled, with a measuring accuracy of 0.1%. The meter features the MFC300 converter, and is available in a compact or remote version. All signal processing is carried out by the MFC300, which converts the meter output to a MODBUS RTU communications signal. All calibration data is secured with redundant memory.
