Details of the Flow regulation part ( Figure 1–8 )
The main components are:

one motor-driven valve (1),

a block with a 2.8 mm diameter flat orifice (3).
The hydrostatic pressure drop observed on passage at the throttle in the fluid circuit is used to
deduce the velocity of flow and the flow rate.

three pressure sensors upstream and downstream of the flat orifice : P1 (4), P2 (2) and
atmospheric P not linked to the fluid circuit (5).
(1) motor-driven valve, (2) P2 downstream pressure sensor, (3) flat orifice, (4) P1 upstream pressure
sensor, (5) atmospheric pressure sensor (P. atm.).
