High performance off the shelf: The SFC5500 mass flow controller is now available via distributors worldwide
24 May 2021
Sensirion, the flow and environmental sensors expert, presents its new SFC5500 mass flow controller series. The SFC5500 is the world’s first mass flow controller available via catalogue distribution. The high-performance mass flow controller is calibrated for multiple gasses and comes with push-in fittings, which can be changed easily by the user.
Thanks to the SFC5500’s ultra-wide control range, each device can cover multiple flow ranges found in conventional devices. As a result, only three different versions with different flow ranges are enough to cover most flow rates of interest. This makes the SFC5500 ideally suited for applications in the medical, analytical and industrial sectors. The SFC5500 is now available worldwide through Sensirion’s distribution network.
The SFC5500 mass flow controller series represents the culmination of Sensirion’s excellent 20-year track record in precision control of gas flow. The sensor is based on the microthermal measurement principle and makes use of Sensirion’s proven CMOSens® MEMS Technology. This allowed us to build an innovative mass flow controller with best-in-class performance and excellent reliability, which – unlike most other devices on the market – does not drift and does not require in-service re-calibration.
Thanks to the exceptionally high control range enabled by the CMOSens® MEMS flow sensor, the SFC5500 series can cover multiple flow ranges found in traditional mass flow controllers in a single device. Coupled with multi-gas calibration and exchangeable fittings, the SFC5500 series offers the first mass flow controllers on the market that are available as standard off-the-shelf products and are suitable for a wide range of applications. Thanks to this versatility, the SFC5500 series are also the first mass flow controllers available via catalog distributors.
The SFC5500 series complements the SFC5xxx family of Sensirion’s best-in-class mass flow controllers. It offers the same top performance as the SFC5400 and is therefore suitable for a broad range of applications in medical, analytical and industrial environments. However, unlike the highly configurable SFC5400 series, the SFC5500 series mass flow controllers are available in several standard pre-configured variants. For other gasses, flow ranges, fittings and interfaces, please check the SFC5400, or Sensirion’s most cost-efficient OEM solution – the SFC5300.

Mass Flow Meter SFM5400
SensirionThe SFM5400 mass flow meter measures mass flows with outstanding accuracy (errors < 1%), long-term stability and repeatability and covers an impressively wide dynamic measurement range. The SFM5400 is made of metal and highly configurable. It is available with a variety of fluidic connections and various interfaces and measures maximum flow rates between 50 sccm and 100 slm. The sensor signal is directly converted into a digital, completely calibrated and temperature-compensated signal on the chip. Multiple gas calibrations can be stored on a single device. Additionally, the flow meter can check whether the activated gas calibration matches the actual gas present. The SFM5400's versatility makes it the ideal solution for industrial and medical applications. The outstanding performance of the SFM5400 mass flow meter is based on the innovative CMOSens® Technology, which integrates the high-precision sensor element and the analog and digital processing electronics on a single CMOS silicon chip. Combined with high-quality materials, the result is a durably stable, extremely fast and highly precise mass flow meter. The SFM5400 mass flow meter is the valve-free version of the SFC5400 mass flow controller. The SFC5400 mass flow controller has the same performance characteristics as the mass flow meter and is used in similar applications, and the two products can be ideally combined. You can find further information and detailed specifications about the mass flow controller on the SFC5400 website. Features High accuracy at low flow rates (< 1 sccm) Excellent accuracy / repeatability (0.8% / 0.1% of measured value respectively) Wide dynamic range (turndown ratio 1000:1) Multiple gases and gas recognition Digital and analog interfaces Flexible mechanical connection options: down mount, VCR and VCO, Swagelok, C-/W-Seal, etc. Highly configurable MTBF 169 years - no recalibration required
