Equipment manufacturers are always looking for compact solutions to monitor or control the gas pressure in their system. Previously, conventional pressure meters and controllers have needed a footprint of 1.5″, as for instance specified in the NeSSI system.
Bronkhorst has developed the IQ+FLOW compact pressure meters and controllers in cooperation with TNO-TPD (leading Institute for Applied Physics). Due to the use of micro solid state technology (MEMS), the footprint of this pressure meter / controller is 0.75″. This is half the size of standard pressure meters, thereby realizing an ultra compact pressure meter and controller. Additionally available is the IQ+FLOW flow meter and controller.
The IQ+FLOW Series Compact Pressure Meter and Forward or Backward Pressure Controllers are innovative microprocessor instruments that offer high accuracy and repeatability. The PID controller on the pc-board ensures highly stable control. As an option, this allows for the adjustment of the settling time down to 300 msec. This is especially useful for processes that require fast response times.
These miniature devices are ideal for use in small environments or in systems requiring minimum internal volume. The ultra compact IQ+FLOW Series pressure instruments are ideal for integration in analytical and medical equipment. Communication with the devices can be either in analog mode or digital over RS232 or RS485.
Previously, conventional pressure meters and controllers require a footprint of 1.5 inches. For example, as specified in the NeSSITM system. In close cooperation with the Netherlands organization for scientific research TNO, Bronkhorst now offers the IQ+FLOW compact pressure meter and controller. Due to the use of microsystem technology (MST), this pressure meter and controller series comes with a footprint of only 0.75 inches. Moreover, this creates an ultra compact pressure controller for 0.025 to 10 bar.
The use of micro fluidic devices for research and analytical purposes has some important advantages. Firstly, because the internal volumes within the instruments are very small, the analysis will be faster. In addition, it allows for the reduction in the amount of reagents and analytes necessary. The latter is especially significant for expensive reagents.
Furthermore, the physical dimensions are much smaller than those of conventional devices. This enables Life Sciences system integrators to downscale the size, inherently reducing the costs of ownership of their equipment. Also, the availability of compact and lightweight instruments could lead to the development of portable systems.
A core philosophy of Bronkhorst is to form close working links and collaborations with Original Equipment Manufacturers (OEM). As a result, we’re able to ensure optimal integration of pressure instrumentation within their own equipment. Most often, we develop a custom design that combines multiple channels and/or various functions into one micro fluidic system.

This forward pressure controller has a chip (MEMS) sensor and is ideal for pressure ranges between 0.025-0.5 bar and 0.5-10 bar absolute or gauge.
For example, analytical applications that use the ultra compact modules with a footprint of 0.75” are:
Gas chromatography involves vaporizing a sample that then injects into a chromatographic column. The sample transports through the column by an inert carrier gas flow. Then it flows into a detector. The detector responds to various chemical compounds of the sample. Programming the pressure at the inlet of the column can optimize GC separations, thus making use of a pressure controller.
To improve gas chromatograph calibrations, we offer a Vapor Generation System. This Vapor Generation System is an all-in-one setup that incorporates a gas flow meter, liquid flow meter, a Controlled Evaporative Mixing (CEM) device, and a user-friendly, color touchscreen interface. As a result, operators have ultimate control over their process. Rack-mount and table top styles are both available, depending on the requirements of the application and operator.
