Product Description:

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.
