4.3.7 Multi-parameter flow chamber
Note: Suitable only for gaseous media.
The ORBISPHERE 32002.xxx multi parameter flow chamber can accommodate one or two
sensors and one sample pressure sensor. If only one gas sensor is used, the unused socket is
plugged with the stainless steel plugs provided (model 28123). The flow chamber is connected
to 6 mm or ¼" stainless steel tubing by two Swagelok™ fittings. If necessary, copper or plastic
tubing with a very low permeability can be substituted.
The flow chamber should be mounted in such a way that the sample outlet port is located at the
lowest point to allow condensation to escape with the outgoing gas. Attach the flow chamber to
a vertical support with the screws supplied. The pressure sensor must be on top.
Note: A user manufactured spacer (~15 mm thick) may be used between the flow chamber and support for
improved access for sensor removal.

• gas sensor (right),
• pressure sensor (center),
• optional second sensor (left)
