IQ+FLOW® Chip-sensor based
Pressure Meters / Controllers


Equipment manufacturers are looking for compact solutions to monitor or control the gas flow or pressure in their system. Previously, conventional Mass Flow and Pressure Meters and Controllers have needed a footprint of 1.5", as for instance specified in the NeSSITM system. Due to the use of micro solid state technology (MEMS), Bronkhorst has been able to halve the footprint dimension to 0.75", thereby realizing the ultra compact flow and pressure controllers.

High intrinsic quality, featuring...

  • Pressure ranges of min. 0,016...8 psi / max. 3...150 psi (other ranges on request)
  • Very stable Zero
  • Compact assembly ensures space efficiency
  • Economical solution, low cost of ownership
  • Fast response
  • Analog and digital (RS232 / RS485) communication

Customer specific designs

Based on the micro system technology of IQ+FLOW® series, Bronkhorst also offers the possibility to combine functional modules on a compact manifold. See IQ+FLOW manifold solutions

Analytical applications

Examples of analytical applications based on the ultra compact modules with a footprint of 0.75" are:

  • Flow - Pressure control at the injector side of a GC
  • Flow control at the detector side of a GC or HPLC
  • Flow control in an FID detector
