TM
Precision Mass Flow Meters / Controllers for
Liquids and Gases
Introduction
Bronkhorst Cori-Tech B.V. manufactures precise, compact Mass
Flow Meters and Controllers for gases and liquids, based on the
Coriolis measuring principle. The instruments are made to
customers’ specification, suitable for use in laboratory, for
integration in manufacturing machines and pilot plants and
even for application in industrial or hazardous areas.
CORI-FLOWTM series direct mass flow
meters and controllers
Bronkhorst, specialists in low flow measurement and control,
designed the CORI-FLOWTM series mass flow metering
instruments to provide high accuracy in two classes:
±0,2% or ±0,5% of Reading.
CORI-FLOW TM utilises a patented, advanced Coriolis type mass
flow sensor to achieve unsurpassed performance, even with
changing operating conditions in pressure, temperature, density,
conductivity and viscosity. The instruments are offered as
separate flow meters or with close-coupled control valve or
pump, thus constituting a compact Coriolis-type mass flow
controller. The instruments have analog (0-5 Vdc / 4-20 mA) and
RS232 output as standard and can, as options, be equipped with
interface to Profibus-DP®, DeviceNetTM, Modbus-RTU or FLOW-BUS.
There are 4 models with overlapping nominal flow ranges from
200 g/h up to 600 kg/h (full scale value), each offering “multirange” functionality: factory calibrated ranges can be rescaled by
the user, maintaining the original accuracy specs. Both meters and
controllers are equipped with an IP65 weatherproof housing and
are available with ATEX approval for use in Zone 2 hazardous areas.
Fields of application
CORI-FLOWTM instruments are applied in process fluid measurement
or control systems in food, (petro-) chemical and pharmaceutical
industries, in fermentation installations, in semiconductor
processing and in fuel cell technology. Some typical examples of
applications are described further on in this brochure.
