Bronkhorst develops and manufactures thermal and Coriolis instruments for measuring and dosing the flow of gases and liquids. With a wide range of instruments, Bronkhorst offers innovative solutions for many different applications in many different markets. Their instruments are made to customer specifications, in various styles suitable for laboratory, industrial environment, hazardous area, semiconductor or analytical installations.

Previously, conventional mass flow and pressure meters and controllers have needed a footprint of 1.5″, as for instance specified in the NeSSITM system. Bronkhorst has developed the IQ+FLOW mass flow sensor; the smallest mass flow and pressure meter/controller in the world.

Due to the use of micro system technology (MST), Bronkhorst has been able to halve the footprint dimension to 0.75″, thereby realizing ultra-compact flow controllers for flow rates from 0.2 to 5000 sccm (mln/min) and pressure controllers for 0.3 to 150 psi.

Thanks to the modular concept of the IQ+FLOW series, multiple channel arrangements can be realized on one compact manifold, with one multi-channel digital pc-board (per 3 channels) in one housing.

A combination of these modules can be mounted on a compact manifold in line with customer requirement. Options include aluminium or stainless steel manifolds. As there are truly an infinite number of possibilities we recommend you contact your local Area Sales Manager or the Bronkhorst UK Ltd Sales office.

IQ+ Flow Mass Flow Meters and Controllers are sophisticated microprocessor based instruments offering high accuracy and repeatability. Up to 8 calibration curves can be stored on the instrument, eliminating the need to recalibrate the device for different gases. The PiD controller, integrated on the pc-board ensures highly stable control and as an option, allows adjustment of settling time down to 200 msec for processes that require a fast response time.

With their unsurpassed expertise in the field of low flow measurement and control of both gases and liquids, Bronkhorst offers precision equipment that is ideally suited to meet the critical requirements of micro fluidic research and system integration.
