EX-FLOW

EX-FLOW EX-PROTECTED MASS FLOW METERS / CONTROLLERS FOR GASES

ATEX Zone-1 Certified (Intrinsically Safe)

EX-FLOW instruments are thermal Mass Flow Meters (MFM) / Controllers (MFC) of rugged design and suitable for gas flow application in hazardous areas (MFM only). The intrinsically safe measuring head 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.

Other certifications (MFM only):

• IECEx = IECEx DEK14.0060
  
• TIIS = 検・第TC21584号 (Japanese certification)
  
• KCs = Ex ib IIC T4 (Korean certification)
  
  

The housing of the electronics compartment is to IP65 classification. Control valves can either be integrally or separately mounted, to measure and control gas flows (air-equivalent).

• Lowest range  0,16...8 mln/min
• Highest range  220...11.000 m3n/h (Mass Flow Meter), 7,5...375 m3n/h (Mass Flow Controller)
