AwiLAB Gas analysis

9 AwiLAB Gas analysis

The product family AwiLAB was developed especially for laboratory applications in the biogas
sector. In combination with the AwiFLEX gas analysis system, gas production and gas composition
can be automatically controlled and checked during the substrate fermentation. The 

Fig. 24

 shows

the exemplary system setup including the gas analysis device AwiFLEX. The gas samples reach the
AwiLAB extension via the maximum of 7 process connections. The gas quantities can be recorded with
a maximum of 3 milligas counters or drum gas meters per measuring point. AwiLAB organizes the
automatic release for the measurement and the automatic emptying of the bags after the measurement.
The current status can be displayed via a maximum of 7 LED indicator lights.
