Bronkhorst® EX-FLOW Mass Flow Meters (MFMs) are suited for precise gas flow measurement in ATEX Zone 1 hazardous areas. The MFM should be connected to a power supply with galvanic isolation / preamplifier / readout system (located in the safe zone). See Bronkhorst® E-8000 Series.
EX-FLOW model F-110CX covers flow ranges from 0,15...7,5 mln/min up to 0,2...10 mln/min (N2-equivalent) at operating pressures up to 100 bar.
The intrinsically safe measuring head of the flow meter is tested according to ATEX 114 Directive 2014/34/EU and approved under EC-Type Examination Number: KEMA 01ATEX1172, protection II 2 G Ex ib IIC T4 Gb.
ATEX approval Cat.2, Zone 1
Also IECEx and TIIS certified
Lowest gas flow ranges
Compact design, small internal volume
High accuracy
Virtually pressure and temperature independent
