1.5 Flow manifold

Flow manifold in AE33 allows for different operation modes (see table below). During
measurement inlet air passes Filter spots 1 & 2 with different flow rate, defined by the orifice
2. Air flow through spot1 (S1) is measured by flowmeter 1, flow through a second spot is
calculated as a difference between flow through flowmeters C and 1.
Valve status contains a series of binary values: Valve 4-moving (1=YES/0=NO), Valve 4
(1=ON/0=OFF), Valve 3 (1=ON/0=OFF), Valve 2 (1=ON/0=OFF), Valve 1 (1=ON/0=OFF).
