IQ+FLOW®
Micro Fluidic Manifold Solutions for Mass Flow and Pressure Measurement / Control

General

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. Now, and in close co-operation with TNO-TPD (leading Dutch institute for applied physics) Bronkhorst has developed the IQ+FLOW® Mass Flow sensor. 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.

Customer specific design

The IQ+FLOW® concept offers the following functional modules:

  • Flow meter; typical flow ranges from 10 mln/min up to 5 ln/min (Full Scale values)
  • Pressure meter; typical pressure ranges of the order of 100 psi
  • Control valve
  • Three-way valve
  • Shut-off valve
  • Filter
  • Mixing chamber

A combination of these modules can be mounted on a compact manifold, in line with a customers requirement, and following open design discussions. Further possibilities might include either an aluminium or a stainless steel manifold with perhaps female inlet/outlet ports that could be suitable for either gas or liquid. As there are truly an infinite number of possible solutions we highly recommend you to contact Bronkhorst to discuss your application.
