Standard measuring system for Biogas - Set BGA


Set BGA (Bio-Gas-Analysis) is one of a series of standardized complete systems for gas analysis which Siemens Process Analytics has developed for certain fields of application. The sets contain all the required components for the relevant application, from gas sampling to operator control and display units in a compact design. Sets are easy to configure and provide considerable user benefits thanks to reduced requirements for planning, engineering, installation, training, and maintenance.

The Set BGA measuring system consists of the four component ULTRAMAT 23 gas analyzer with selectable equipment and I/O components (basic equipment) as well as additive modules.

Efficient sample preparation for fast, reliable and reproducible analytical results is an essential prerequisite for analyzing raw biogas. Up to four sample streams can be chosen for continuous analysis. The sample preparation device is fitted in a rugged enclosure in which a cabinet heater can be accommodated (to avoid condensation moisture when installed outdoors) in addition to a suction pump.

With the Set BGA Siemens offers another standard solution, which is not only extremely economical, but also helps to optimize the processes.


Measuring components

CO2, CH4, O2, H2S

Basic equipment

Wall or rack mounting including flame arrestor

Sample preparation

Up to four streams


Reduced operating and maintenance costs:

  • Monitoring of several fermenters using one device via measuring point switchover function

  • Can be ordered from catalog, supplied ready-to-run, minimum installation efforts

Particularly high operational reliability, long-term stability and availability:

  • Industry-compatible, extremely rugged mechanical and electrical design

  • High service life of the H2S- sensor; no dilution or back-flushing required

Particularly high measuring accuracy and safety:

  • No dilution of sample gas required

  • Suitable for connection of flammable gases at high concentration (as is the case with biogas) in accordance with TÜV (German Technical Inspection Association) report

Simple integration into process systems by using open interface architecture including fieldbus (optional)
