IECEx and ATEX approved design
The compact mass flow meters of mini
CORI-FLOW™ series M12-M14 can be built in an explosion proof housing
for use in IECEx and ATEX Zone 1 hazardous areas, ATEX approval II 2 G
Ex d e IIB T6 Gb. The mini CORI-FLOW™Ex
d series are designed for small flow rates, from 100 mg/h up to
30 kg/h, both for liquids and gases.
Superior Coriolis flow sensor
Instruments of the mini CORI-FLOW™
Ex d series contain a uniquely shaped, single loop sensor tube,
forming part of an oscillating system. Coriolis mass flow
measurement is fast, accurate and inherently bi-directional. The mini
CORI-FLOW™ Ex d features density and temperature of the fluid
as secondary outputs.
Mass Flow Control
mini CORI-FLOW™ Ex d mass
flow meters offer integrated PID control for direct control of valves or
pumps, thus constituting compact Coriolis mass flow control loops. Valves
or pumps to be used in Zone 1 can also be provided with the meter, but
have to be installed outside the Ex d box, to be electrically connected
to the screw terminal of the unit.
Fields of application
mini CORI-FLOW™ instruments
can be applied in process control systems as for example in chemical, petrochemical
and pharmaceutical plants, such as dosing systems for gas odorization and
additive control for scale/corrosion inhibitor for oil pumps.
