1.8.6 Flow Chamber
The flow chamber inlet and outlet should be free of any obstructions. The model 32013A flow chamber, for dissolved N2 measurements, has a flow adjustment valve on the outlet. The model 32015 flow chamber for H2 measurements has no valve.
Dissolved Gas Measurements
Adjust the sample flow rate using the needle valve on the exit. When analyzing carbonated beverages, sufficient pressure must be provided to avoid degassing of the beverage during its passage through the flow chamber. Check for the absence of bubbles in the inlet tubing.
Gaseous Measurements
Place the outlet tubing in a container of water, ensuring that the flow chamber outlet is unobstructed (on the 32013A flow chamber, open the outlet valve completely). Then, adjust the inlet sample flow valve (main supply) to obtain one bubble per second at the outlet.
