KROHNE Messtechnik GmbH
Coriolis Mass Flowmeter
FOUNDATION Field Device
The OPTIMASS Family of Coriolis mass flowmeters
OPTIMASS 1000 the dual straight tube meter for process control and
OPTIMASS 2000 the dual straight tube meter for bulk flow measurements and
OPTIMASS 3000 the low flow bent tube meter with a high safety factor
OPTIMASS 7000 the single straight tube meter for high end and CT
No limits with tube materials
Titanium, Hastelloy, Stainless Steel, Duplex, Super Duplex, or Tantalum
allow straight tube metering for almost any process.
No limits with flow
From 0.3 to 2,300,000 kg/h with a full range of meters for low, normal
and bulk flow applications.
No limits with measured product
High viscosity, particulate matter, inhomogeneous mixtures, normal
entrained air, have little effect on the accuracy of the measurement.
No limits with installation
Support on the process pipe or the meter body, without the need for
accurate positioning. A complete range of process connectors for all
existing and future installations is available.
No limit with electronics
OPTIMASS has been designed with all new electronics, which incorporates
Front End signal processing that is permanently mounted to the meter.
This provides high speed and low noise measurement, as well as remote
connection to the signal converter up to 300 m. Dual redundancy of
configured data, calibration constants etc ease maintenance.
No limits with applications
KROHNE can provide metering solutions whatever your requirement
including: Flow, Density, Concentration and Temperature.

Adaptive Sensor Technology AST
KROHNE has re-designed the Coriolis flowmeter from the inside out to
produce an instrument that is inherently balanced under all operating
The result is a meter that can cope with the most demanding process
conditions and still deliver accurate and reliable measurement time after
time. KROHNEs patented AST design is extremely stable and will
adaptively tune each meter independent of external forces and fluid
Tried and tested technology
To ensure the highest standards of quality and accuracy, all meters in
the OPTIMASS family have been rigorously tested. Series 1000, 2000,
3000, 7000 and 8000 have been comprehensively trialed at major chemical,
pharmaceutical and food and beverage sites in Europe to actively measure
the mass flow of substances such as margarine, coffee extract or
pesticides, oils and acids and are delivering previously unattainable
levels of performance.

DD/CFF Tester Version:
FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
