Gas flow monitoring with SFS Flow Module by IST AG

The SFS Flow Module is primarily used in gas supply, gas dosing systems, analysers and manifolds, but is also suitable for process control, e.g. in modified atmosphere conditions for the measurement of low flow rates. This makes this flow module ideally suited for integration in medical devices. In environmental technology, the SFS module can be used in measuring instruments for gas analysis and for continuous emission monitoring.

Thanks to its bi-directional calorimetric measurement, the SFS Flow Module provides fast, continuous gas flow monitoring with a response time ≤20 ms. It comes factory-linearised with a repeatability of 0.2% and an accuracy of up to 2% f.s. and is available in three versions for different flow rates +/-50sccm, +/-200sccm and +/-1000sccm. The flow module has both, an analogue and a digital I2C output and is equipped with two address pins. Another advantage of the new SFS Flow Module is its compact design. With an installation space of only 50 x 40 x 20 mm, it is sufficiently small for integration into a measuring unit.
