Figure 5.
Flow schematics for the LI-8150 configured for normal operation (top) and configured for flask measurements
(bottom right). The flow path used during measurements is shown with blue arrows and the flow path used to flush flasks
between measurements is shown with red arrows. In both diagrams the solenoids at port 3 are activated and the chamber
connected there is being sampled. The box in the lower left hand corner shows how the flow path changes inside the
solenoid manifold when a solenoid is activated.
