CGS Inline Aeration Meter

The CGS (Concentration Gas System) is an inline measuring system for the continuous determination of the gas content in fluids. The system works regardless of the size and shape of the entrained gas portions in the
fluid. Therefore both finely dispersed microbubbles as well as large air pockets can be detected correctly in the passing medium, with their percentage by volume displayed in real time.

The following parameters are determined by the CGS:
• temperature (−30 °C to 150 °C)
• pressure (max. 10 bar)
• gas content CGp at measured pressure
• gas content CG0 at atmospheric pressure (recalculation according to the ideal gas law)
