Flowmeters with media-isolated pressure sensors
The IQ+FLOW series of miniature mass flow and pressure meters and controllers is used by equipment manufacturers in the analytical, biotechnology and life science market. The footprint of single channel instruments is only 20 mm by 40 mm, which is advantageous for manufacturers of desktop equipment. The IQ+FLOW product line has now been extended to pressure instruments with media-isolated pressure sensors. The sensor chip is protected by a stainless-steel diaphragm and oil-filled compartment. With this new option, the instruments can handle a much wider variety of media than before, including light gases, such as hydrogen and helium. IQ+FLOW series is available in three configurations: single-channel versions (photo, left) for either inline or top-mount integration and multi-channel versions. Compact two- or three-channel instruments (photo, right) can be configured on user specification to measure or control the mass flow or the upstream or downstream pressure in a system. — Bronkhorst High-Tech B.V., Ruurlo, the Netherlands
