Bronkhorst IQ+FLOW miniature pressure controllers

The Bronkhorst IQ+FLOW series of miniature mass flow and pressure meters and controllers is suitable for equipment manufacturers in the analytical, biotechnology and life science market. Due to the application of chip sensors and mini-valves, the footprint of single-channel instruments is only 20 x 40 mm. This is advantageous for manufacturers of desktop equipment, who are looking to optimise space efficiency.

The product line for miniature pressure controllers has been extended with pressure instruments with media-isolated pressure sensors. The sensor chip is protected by a stainless steel diaphragm and oil-filled compartment. With this option, the instruments can handle a wide variety of media, including thin gases such as hydrogen and helium. According to the requirements of the aforementioned markets, the instruments have low-outgassing and clean wetted parts.

The IQ+ FLOW series is available in three configurations: single-channel versions for either inline or topmount integration and multi-channel versions. Compact 2- or 3-channel instruments can be configured on customer specification to measure or control the mass flow and/or the upstream or downstream pressure in a system.
