Measuring-gas filter

Several filters are integrated into the gas path of the SSM 6000 in order to protect the sensors and other components of the system.
The filters clean the biogas and the ambient air drawn in, thereby increasing both the service life of the sensors and the measuring
precision of the system.
Filter type Function
Aerosol filter Eliminates aerosols and larger dirt particles from the gas sample. Replacement is only necessary if filter
contamination is visible. (Material: glass and steel wool)
Air filter
Filters the ambient air for zero-point determination
at least once a year. (Material: activated carbon)
Chemical filter The chemical filter is also used to filter the zero gas.The filter is slowly used up which can be easily seen by
gray discoloration of the filter material. The filter must be replaced by a new one at the latest when the pink
color of the filter material has vanished.
Fine-dust filters are additionally located at the downstream end of the filter cartridges. These fine dust filters must also be replaced
when strong contamination of the filter is found.

Flow rate display and control

"Flow 2" adjustment is only possible during an H
"stand-by" mode.
800C-07.07.EN
The measuring precision depends, amongst other things, on the measuring-gas volume flows. The
measuring-gas volume flows are measured by the two flowmeters on the front panel of the SSM 6000
and can be adjusted by means of the needle valves located below the flowmeters.
Adjust the flow rates in such a manner that the floating indicators are located between the upper and
lower marks during measurement.
