EX-PROOF CORIOLIS MASS FLOW METERS - mini CORI-FLOW™ EX D series

mini CORI-FLOW™ Ex d Coriolis Mass Flow Meters

Fluid independent Mass Flow Measurement solution for Zone 1 applications

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. All electrical instrument connections are available on screw terminals in an electrical housing connected to the Ex d box. 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. The instruments can be used in systems with pipeline pressures up to 137 bar (1987 psi). The Coriolis flow meter can be equipped with a heater to prevent condensation or solidification inside the instrument. Optionally an additional (external) control unit can be provided to monitor and control the heating temperature.

mini CORI-FLOW™ Ex d models XM12 thru XM14 can be offered for flow rates from

  • lowest range 0…5 g/h
  • up to highest range 0…30 kg/h

Mass Flow Meter for applications in hazardous area, Zone 1

Instruments of the mini CORI-FLOW™ Ex d series contain a uniquely shaped, single loop sensor tube, forming part of an oscillating system. When a fluid flows through the tube, Coriolis forces cause a variable phase shift, which is detected by sensors and fed into the integrally mounted pc-board. The resulting output signal is strictly proportional to the real mass flow rate. 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.
