EX-FLOW Series, Explosion Proof Mass Flow Meters and Controllers

EX-FLOW Series, Explosion Proof Mass Flow Meters and Controllers

Product Overview

EX-FLOW instruments are thermal mass flow meters (MFM) and mass flow controllers (MFC) of rugged design that are suitable for gas flow applications 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 protection II 2 G Ex ib IIC T4 Gb. 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).

EX-FLOW Mass Flow Controller

  • Lowest range 0.16…8 mln/min
  • 7.5…375 m3n/h

Description

  • ATEX approval Cat.2, Zone 1
  • Pressure ratings up to 400 bar
  • Rugged, weatherproof housing (IP65, dust, and waterproof)
  • High flow versions available (up to 11000 m3n/h)

Applications

  • Process gas measurement or control in (petro)chemical industries
  • Fuel cell technology
  • Gas distribution systems
  • Hydrogenation processes
  • Gas consumption measurement for internal accounting
  • Heating or biogas production
  • Explosive mixture composition

Gas Flow Control for Hazardous Areas

The EX-FLOW Mass Flow Controller has a control valve with fast and smooth control characteristics. The flow meter and valve should be connected (via separate cables) to a power supply with galvanic isolation / preamplifier / readout system (located in the safe zone) which contains a controller board to complete the control loop. The control valve receives its input from the controller board and immediately responds to any deviation between the output signal from the flow sensor and the setpoint signal.

Bronkhorst Offers Two Types of Coils:

Style “XB” = intrinsic safe coil; needs safety barrier.
protection II 1 G Ex ia IIC T6
protection II 1 D Ex ta IIIC T80°C

Style “XC” = moulded coil; no safety barrier required.
protection II 2 G Ex eb IIC T4
protection II 2 D Ex tb IIIC T130°C
